For countless extraordinary species, it\u2019s home. When the sun sets, things start to get interesting among wild animals. Wherever we live, whether in the city suburbs, or country, darkness conjures a hidden world of wildlife that most of us rarely glimpse. Foxes, wolves, and bears prowl while skunks, opossums, and porcupines lurk; fireflies send flashing signals to potential mates; raccoons rummage for food; owls and bats fly overhead. Night is not just a time, but a diverse habitat we know little about.<\/p>\n<p>This roundtable wants to shine a light on the habitat night from different perspectives and different parts of the globe. It aims to take readers on a journey to discover the secret city nightlife around the world.

As \u00e1guas, elemento onipresente em Afu\u00e1, ora tocam as bases das sepulturas, ora recuam, revelando a fragilidade da mat\u00e9ria diante da for\u00e7a da natureza. Desse movimento emerge um ar de simplicidade, uma originalidade que brota da adapta\u00e7\u00e3o ao meio, uma beleza melanc\u00f3lica que reside na uni\u00e3o entre a cria\u00e7\u00e3o humana e o dom\u00ednio natural. N\u00e3o h\u00e1 a solidez da pedra ou o isolamento da terra firme, mas uma entrega ao fluxo da \u00e1gua, uma aceita\u00e7\u00e3o da imperman\u00eancia como parte do ciclo da vida e da morte.<\/p>\n<p>A noite, em sua ess\u00eancia, transcende a mera aus\u00eancia de luz; ela \u00e9 um universo \u00e0 parte, um palco onde a vida urbana adquire contornos distintos.

Logo, a densa escurid\u00e3o e os sons da natureza produzem fantasmagorias em uma popula\u00e7\u00e3o j\u00e1 afeita a superestimar as tradi\u00e7\u00f5es locais, sejam elas ligadas \u00e0s hist\u00f3rias de mitos ancestrais ou \u00e0 epifanias que a tradi\u00e7\u00e3o amaz\u00f4nica, atrav\u00e9s dos tempos, construiu. Nesse cen\u00e1rio o cemit\u00e9rio emerge como um espelho da alma da cidade, refletindo n\u00e3o somente a rever\u00eancia \u00e0 mem\u00f3ria dos ancestrais, como tamb\u00e9m se tornando um terreno f\u00e9rtil para o florescimento de hist\u00f3rias sobrenaturais.<\/p>\n<p>Diante de um cen\u00e1rio amaz\u00f4nico que potencializa as mais variadas interpreta\u00e7\u00f5es, o campo santo da cidade adquire camadas distintas quando chega a escurid\u00e3o. A multiplicidade de sons noturnos, diante das tradi\u00e7\u00f5es culturais locais, s\u00e3o um convite para experienciar um ambiente cercado de misticismos, medos e tens\u00f5es. O vento que assobia entre as l\u00e1pides soma-se ao farfalhar das folhas sob os movimentos da coruja.

La multiplicidad de sonidos nocturnos, en presencia de las tradiciones culturales locales, es una invitaci\u00f3n a experimentar un ambiente lleno de misticismos, miedos y tensiones. El viento que susurra entre las l\u00e1pidas se suma al susurro de las hojas bajo los movimientos de la lechuza.

In this context, Amazonian epiphanies and traditions promote provocative visions about understanding daily life, mortality, and the afterlife. The allegories about what is to come serve as a backdrop for stories that resonate deeply within the minds and hearts of those connected to the Afu\u00e1 Cemetery. The frenzy evoking the supernatural, evidenced through omens and rituals, takes on different representations and visualities in the landscape, especially around the cemetery, which embodies the concept of endings and finality. This reflection aims to analyze the symbiosis between human mortality and the force of nature, centered on the city\u2019s cemetery.<\/p>\n<p>Night, in its essence, transcends mere absence of light; it is a universe of its own, a stage where urban life takes on distinct contours. In the case of Afu\u00e1, a place cut through by mighty rivers, surrounded by a monumental forest, and abundant in birdlife, the atmosphere of darkness and sounds naturally fill all spaces and dominate the nighttime landscape. Thus, the dense darkness and the sounds of nature produce ghostly images in a population already prone to overestimating local traditions, whether they are linked to stories of ancestral myths or to epiphanies that Amazonian tradition has built over time. In this scenario, the cemetery emerges as a mirror of the city\u2019s soul, reflecting not only reverence for the memory of ancestors but also becoming a fertile ground for the flourishing of supernatural stories.<\/p>\n<p>Faced with an Amazonian landscape that amplifies a variety of interpretations, the city\u2019s cemetery takes on different layers when night falls. The multiplicity of nocturnal sounds, given the local cultural traditions, invites one to experience an environment filled with mysticism, fears, and tensions. The wind whistling among the tombstones adds to the rustling of leaves under the movements of an owl. The croaking of frogs, bats in flight, and the distant cry of a raptor are also present. All these sounds provoke the imagination and serve as catalysts for the ancestral fears that inhabit the collective unconscious. In this way, a wild and sensitive game arises between nature and the human psyche. The rich local fauna, with its nocturnal habits, combined with the movement of the tides that floods the entire cemetery with its unchanging rhythm, not only compose the melody of the Amazonian night but also create a peculiar mythology that redefines the relationship between local culture and the environment surrounding the cemetery each day.<\/p>\n<p>In the almost tangible silence of darkness, each indistinct sound becomes an invitation to fantasy, fueling belief in the inexplicable. At night, near the cemetery, it is not just dark; it is inhabited by an orchestra of sounds that, for minds permeated by folklore and tradition, echo the whispers from beyond, transforming the nocturnal habitat into a portal to mystery and fear.<\/p>\n<\/div><div class=\"answer\">\n    <div class=\"wp-biographia-container-around\">\n        <div class=\"wp-biographia-pic\"><img alt='Madhusudan Katti' src='http:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2012\/10\/MadhuKatti_avatar.jpg' srcset=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2012\/10\/MadhuKatti_avatar.jpg 2x\" class='avatar avatar-125 photo wp-biographia-avatar' height='125' width='125' \/><\/div>\n        <div class=\"wp-biographia-text\">\n            <h3>about the writer<br>\n                <a href=\"https:\/\/www.thenatureofcities.com\/TNOC\/author\/madhukatti\/\">Madhusudan Katti<\/a>\n            <\/h3>\n            <p>Madhusudan is the Director of Science, Technology, and Society, and Associate Professor of Public Science in the Department of Integrative Humanities and Social Sciences at North Carolina State University.<\/p>\n        <\/div>\n    <\/div>\n    \n<h3 id=\"Madhusudan\">Madhusudan Katti<\/h3>\n<figure class=\"wp-block-pullquote\"><blockquote>Can we turn off or at least dim all these city lights, please?

Before birds hooked me, I was awestruck by Flying Foxes, giant fruit bats that took wing in the twilight, emerging from their roosts to take over my hometown, India\u2019s Gotham City searching for the myriad figs and other fruiting trees lining Mumbai\u2019s parks and streets.<\/p>\n<p>My obsession with birds amplified my stargazer\u2019s longing for clear dark skies where one could see the Milky Way. I fled the city for a while and went deep into the jungles of southern India to study migratory warblers. There, when waking up at dawn to catch birds, I met another creature of the night, a tiny primate named the Slender Loris, endemic to that region. I learned how important darkness was to both types of creatures: one undertook long nocturnal flights between breeding and wintering grounds while the other shied away even from moonlight.<\/p>\n<p>Just as astronomers fretted about being able to observe distant galaxies to uncover the secrets of the early universe amid the ever-growing glow of city lights everywhere, wildlife biologists also worried about what so much light was doing to all the species that loved the dark but had no say in the matter as humanity sought to banish the night.<\/p>\n<p>Now I am back to living in a city, teaching urban wildlife ecology, and joining my birder comrades in urging cities to turn down the lights at least for a few weeks every Fall and Spring when billions of birds migrate, most flying right over our heads through the night. Bright city lights are a real and present danger because they confuse and disorient birds whose navigational apparatus evolved in the pre-urban dark age. Likewise, I have friends who patrol tropical beaches at night to protect sea turtles that crawl out of the ocean annually to nest along the shore; their hatchlings also get confused by well-lit urban shores because they evolved to find the sea by seeking the lighter sky over the ocean, not land.<\/p>\n<p>Urban light continues to ruin the essential magic of night, yet many creatures are adapting to city life. Even the slender loris can be seen in cities like Bengaluru, where I\u2019ve spotted them sneaking through the tree canopy, right over the heads of oblivious humans afraid of the dark.<\/p>\n<p>One lowly species I find kinship with is the Dung Beetle, who got that name for rolling up the dung of large herbivores into balls in which to lay eggs. Surprisingly, these busy little scavengers who keep us from drowning in a sea of dung actually look up to the sky and use the Milky Way to keep themselves oriented at night while scuttling backward with their precious dungballs. Who would\u2019ve thought? But what of dung beetles that now find themselves surrounded by disorienting urban lights? They latch on to some bright light and end up going in less hospitable directions in the treacherous urban landscape. Just like the turtles who can\u2019t find the ocean, and the birds that fly into brightly lit buildings.<\/p>\n<p>Can we turn off or at least dim all these city lights, please? As much for our fellow nonhuman citizens as for our own souls that also evolved to rest at night, looking up into the dark sky pondering our existence. What shall I tell the dung beetles when they ask why we hid their Milky Way?<\/p>\n<\/div><div class=\"answer\">\n    <div class=\"wp-biographia-container-around\">\n        <div class=\"wp-biographia-pic\"><img alt='Carolina Rodrigues' src='https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/01\/Carolina-Rodrigues-125x125.jpg' srcset=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/01\/Carolina-Rodrigues-250x250.jpg 2x\" class='avatar avatar-125 photo wp-biographia-avatar' height='125' width='125' \/><\/div>\n        <div class=\"wp-biographia-text\">\n            <h3>about the writer<br>\n                <a href=\"https:\/\/www.thenatureofcities.com\/TNOC\/author\/carolinarodrigues\/\">Carolina Rodrigues<\/a>\n            <\/h3>\n            <p>Scientific Coordinator at the Landscape Laboratory (Guimar\u00e3es), an institution dedicated to Environmental Research and Education.

Receiving a kick or a punch from a moth, no matter how big our little friend is, would never really harm us. Don\u2019t panic\u2014moths have not been trained in martial arts for self-defense. \u201cKarate\u201d is a beautiful metaphor, and its power comes from a deeper source: vernacular narrative and popular knowledge.<\/p>\n<p>At dusk, a ritual unfolds in most Costa Rican homes: the closing of doors and windows to keep out insects\u2014moths and beetles alike. Looking for shelter or attracted by indoor lights, these creatures often find their way inside, making interaction with them imminent.\u00a0<em>Moths Karate<\/em>, as my grandmother Hortensia used to call it, could cause a painful rash or an annoying allergy. The intensity of the effect seemed to change as I grew up. According to Hortensia, the closer you get to them, the stronger the reaction. Touching them was strictly off-limits\u2014yet unavoidable due to curiosity.<\/p>\n<p>Moths belong to the\u00a0<em>Lepidoptera<\/em>\u00b9 order. Their wings and bodies are armored with micro-scales that function in thermoregulation, aerodynamics, as well as chemical and physical defense. These alchemists are known to use methoxypyrazines\u00b2 and pyrrolizidine alkaloids\u00b3 (PAs) during both larval and adult phases. For physical defense, they evolved to use aposematic warning\u2074 signals and to rely on the pareidolia\u2075 effect in humans\u2014a large set of skills designed to deter predators from eating or harming them. By shaking their wings, nocturnal moths release a spore-like, atomized compound from their scales, designed to ward off predators and curious humans alike. Such fluttering also aids in pollination, giving flowers one final push while in flight.<\/p>\n<p>Cultural barriers have long been used to control human behavior\u2014often going against our natural instincts. For many, moths are portrayed as omens of the night; they became archetypes in mythology and superstition. This has been a stronger source of influence than chemicals. Much of their behavior has remained unseen, recorded only by those who dwell in infamous, hidden nightly spaces. This demeanor worked very effectively for moths\u2014having a maleficent and toxic halo has likely secured their survival in urban Costa Rica. Beyond Costa Rica\u2019s worldwide reputation, fear has transformed into respect, and respect has mutated into conservancy.<\/p>\n<p>Hortensia was very effective at teaching respect and love for nature to her progeny. She grew up on a coffee plantation, aware of the balance needed for things to flourish. Coffee landscapes back then were mainly nourished by biodiversity\u2014even with the \u201canimosity\u201d of a mythic creature. Moths helped pollinate the white, reflective blossoms of the coffee plants through the dark hours. Now I wonder: hidden beneath the warning of harm lies a preserving narrative, taught by grandmas\u2014perhaps one designed to keep the land producing coffee 24 hours a day, thanks to the unrecognized labor of moths. Or, as I prefer to think, one guided by colloquial fiction and intergenerational love for all living things.<\/p>\n<p><strong>Footnotes (APA Format):<\/strong><\/p>\n<p>\u00b9\u00a0<em>Lepidoptera<\/em>\u00a0is the order of insects that includes moths and butterflies, characterized by scaled wings (National Geographic Society, n.d.).<\/p>\n<p>\u00b2 Methoxypyrazines are aromatic compounds used by insects as chemical signals or deterrents against predators (Boppr\u00e9, 1984).<\/p>\n<p>\u00b3 Pyrrolizidine alkaloids are toxic compounds sequestered by insects from host plants, often used as a defense mechanism (Hartmann, 1999).<\/p>\n<p>\u2074 Aposematic warning refers to bright colors or patterns that signal toxicity or danger to predators (Ruxton et al., 2004).<\/p>\n<p>\u2075 Pareidolia effect is the tendency of humans to perceive familiar patterns, such as faces, in unrelated objects or shapes (Liu et al., 2014).<\/p>\n<\/div><div class=\"answer\">\n<h3 id=\"Seema\">Seema Mundoli and Harini Nagendra<\/h3>\n<div class=\"addon_bios\">\n    <div class=\"wp-biographia-container-around\">\n        <div class=\"wp-biographia-pic\"><img alt='Seema Mundoli' src='https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2018\/02\/Seema-Mundoli_avatar_1519064761-125x125.jpg' srcset=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2018\/02\/Seema-Mundoli_avatar_1519064761-250x250.jpg 2x\" class='avatar avatar-125 photo wp-biographia-avatar' height='125' width='125' \/><\/div>\n        <div class=\"wp-biographia-text\">\n            <h3>about the writer<br>\n                <a href=\"https:\/\/www.thenatureofcities.com\/TNOC\/author\/seemamundoli\/\">Seema Mundoli<\/a>\n            <\/h3>\n            <p>Seema Mundoli is an Assistant Professor at Azim Premji University, Bengaluru.

Residents, returning home at dusk from work, can glimpse these bats.<\/p>\n<p>Around the lakes of Bengaluru, a night walk in the monsoon is like walking into a wall of sound, a cacophony of frogs performing in an impromptu rock band concern. Bengaluru is also home to endangered and rare species such as the nocturnal slender loris (<em>Loris lydekkerianus cabrera<\/em>). A primate species, the loris is arboreal and sleeps during the day, active only in the night when it spends much of its life moving from one tree canopy to another, in search of food and a mate. They have a whistling call, and eyes that reflect the light of the torches used to spot them. Slender lorises feature in the cultural beliefs of city residents, especially the old-timers. Some believe that they are bad omens that bring death and misfortune, but others see them as bringing good luck, especially to children.<\/p>\n<p>In Hyderabad, bat species dart among trees such as the Singapore cherry (<em>Mutingia calabura<\/em>), Indian mast (<em>Monoon longifolium<\/em>)and cluster fig (<em>Ficus racemosa<\/em>), feasting on the ripe fruits or snatching insects that are attracted to the streetlights. There are birds too, of many different kinds. The late-night peace of apartment complexes, where families are relaxing after a long day, can be shattered by the eerie screech of barn owls (<em>Tyto alba<\/em>). And in peri-urban layouts, where the city exists cheek-by-jowl with lakes and wetlands, we can still hear the \u201cdid-you-do-it\u201d call of the red-wattled lapwing (<em>Vanellus indicus<\/em>), flapping its wings as it flies over an open field or grazing area, returning home in the late evening when dusk gives way to nightfall.<\/p>\n<p>In the coastal city of Chennai, the night is the time when the female olive ridley (<em>Lepidochelys olivacea<\/em>) sea turtles come to shore, laying their eggs on the beach. There are only seven species of sea turtles across the world. A fascinating feature about the olive ridley is that the females return to the very same beach to nest from where they hatched. While there are many theories as to how turtles return to their natal beaches, none have been proven yet. But because they come to the beaches at night, very few in the 12 million population of the metropolis of Chennai know about these fascinating and vulnerable species.<\/p>\n<p>But cities are no longer safe havens for these nocturnal species. As green and blue spaces disappear, destroyed by rapid urbanisation, the denizens of the night are struggling to survive. The slender loris of Bengaluru needs overlapping tree canopies, so that it can jump from the branches of one tree to another, moving across the city in search of food, mates, and nesting spots. As trees are cut down for road widening and to build flyovers, the tree canopy that is critical to their survival is being fragmented. The lakes of Hyderabad are being \u2018restored\u2019 by cementing the mud banks, destroying the habitat for reptiles and amphibian species. The sea turtle hatchlings in Chennai are drawn away from their destination by the bright lights from the city\u2014away from the ocean towards their death.<\/p>\n<p>A city is, of course, home to humans. But it is also home to non-human species, and we need to prioritise their protection for the ecological, social, and cultural relevance of these species in our lives. And there are initiatives that give us hope. In Bengaluru, citizen science initiatives, such as the Urban Slender Loris Project, helped to raise awareness about this reclusive species, and the need to protect the avenue trees and wooded patches that constitute their primary habitat. Similarly, the Student Sea Turtle Conservation Network (SSTCN), which began in the 1970s, has conducted turtle walks along the beach to monitor egg laying by females, relocating nests to a hatchery where the eggs have a better chance of survival. The turtle walks draw in people from Chennai and across the country, volunteers who participate in this effort to create awareness and protect sea turtles.<\/p>\n<p>Our cities may not be as rich in biodiversity as the jungles of Kipling\u2019s books. But they need to be more than \u201cconcrete jungles\u201d \u2015 a reference to the many unpleasant aspects of city life. With careful consideration for protecting green and blue spaces, and some awareness of how to reduce light and noise pollution in the night \u2015 to protect the city\u2019s nocturnal residents \u2015 we can make the night in the city a more just and safe place and time for non-human species too.<\/p>\n<\/div><div class=\"answer\">\n<h3 id=\"Aliyu\">Aliyu Barau<\/h3>\n    <div class=\"wp-biographia-container-around\">\n        <div class=\"wp-biographia-pic\"><img alt='Aliyu Barau' src='https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/AliyaHeadshot-125x125.png' srcset=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/AliyaHeadshot-250x250.png 2x\" class='avatar avatar-125 photo wp-biographia-avatar' height='125' width='125' \/><\/div>\n        <div class=\"wp-biographia-text\">\n            <h3>about the writer<br>\n                <a href=\"https:\/\/www.thenatureofcities.com\/TNOC\/author\/aliyubarau\/\">Aliyu Barau<\/a>\n            <\/h3>\n            <p>Professor Aliyu Barau is a trans-disciplinarian climate change expert and landscape ecologist.

What happens when the first rains drop?

Just before the rainy season, the weather would be very hot and hotter in the daytime. At nightfall, we would sit outside the room to take fresh air. When the national grid falls, we have better chances as we will do some astronomy by watching the stars that flicker in the sky and define their mythological meanings. Such sky-watching time could be interrupted by a near stampede scenario as we race to chase mice or rats that emerge from nowhere. Sometimes, it is costly when some scorpions leave their holes and hiding habitats and unleash their weapons, and they are not alone. Spiders, geckos, ants, and cockroaches are feared most by girls while boys try to kill them\u2015a kind of an undying conflict. A ferocious dog barks from the back of the house, signaling the fear of thieves in the neighbourhood. We can distinguish that from normal time barking.<\/p>\n<figure id=\"attachment_58165\" aria-describedby=\"caption-attachment-58165\" style=\"width: 250px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-58165\" src=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/Barau1.jpg\" alt=\"A picture of a dead tree in a field\" width=\"250\" height=\"334\" \/><figcaption id=\"caption-attachment-58165\" class=\"wp-caption-text\">Baobab trees are indigenous plants and are good habit for bats and host nests of some birds.

Some mornings, we wake up to see what we cannot do with our trees is done very well by the bats and other nocturnal bats. While we cannot climb the top and delicate tree branches bats will do and will throw down half-eaten fruits. These fruits are forbidden for us as we cannot eat the food remnants of bats. The fruit bats that roam the night skies and feast on our trees\u2019 fruits are basically two species\u2015the bigger and smaller ones\u2015Megachiroptera and Microchiroptera. As kids, we understand that both the former (called <em>Jemage<\/em> in Hausa) and the latter (called <em>Birbiri<\/em>) cannot fly again once they touch the ground. But we actually confuse the smaller ones for babies of the bigger ones. But in reality, we are afraid of them and can only use small sticks to flip them over and over and just observe. The brave among us lift them up and sometimes they fly and run away.<\/p>\n<p>I am now nostalgic for those great nights of low lights and low noise. My children don\u2019t experience much of sitting outdoors in the night. They don\u2019t play much with insects as they see that as unhygienic. But they all read about fireflies in the storybooks. Why? Everywhere is more lit, and the light is undying because of the solar lights. The grounds are covered by tiles and the house is full of ornamental plants which is too bad for the nature at night.<\/p>\n<\/div><div class=\"answer\">\n    <div class=\"wp-biographia-container-around\">\n        <div class=\"wp-biographia-pic\"><img alt='Tanja Straka' src='https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/Straka_2023-scaled-125x125.jpg' srcset=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/Straka_2023-scaled-250x250.jpg 2x\" class='avatar avatar-125 photo wp-biographia-avatar' height='125' width='125' \/><\/div>\n        <div class=\"wp-biographia-text\">\n            <h3>about the writer<br>\n                <a href=\"https:\/\/www.thenatureofcities.com\/TNOC\/author\/tanjastraka\/\">Tanja Straka<\/a>\n            <\/h3>\n            <p>Tanja is a guest professor in Urban Ecology at the Freie Universit\u00e4t Berlin, with a PhD from the University of Melbourne.

Bridging ecology and social science, her work explores human-wildlife relationships, the drivers of human behaviour, and the impacts of anthropogenic stressors on urban biodiversity, with a special love for bats. Tanja collaborates closely with NGOs and her career has taken her across Europe, West Africa, India, New Zealand, and Australia.<\/p>\n        <\/div>\n    <\/div>\n    \n<h3 id=\"Tanja\">Tanja Straka<\/h3>\n<figure class=\"wp-block-pullquote\"><blockquote>If you have not yet had the chance to experience bats in your city, I want to encourage you: go to a nearby waterbody on a warm summer night.<\/blockquote><\/figure>\n<p>The dark hours in the city were when my work usually began. I have spent countless evenings and nights standing in urban parks, next to urban waterbodies, or even in parking lots and was waiting for the first signs of movement. There is this special moment after sunset, when the last warmth of the sun fades and the city seems to get quiet. And no matter which city I was in, there was always that moment when I heard the first tiny signal on my bat detector. That moment when I also looked up and could see the first bats fluttering around, passing by, or chasing insects. My working hours have begun.<\/p>\n<p><em>What is the nature of these dark hours in cities<\/em>? Although our understanding of nocturnal organisms still lags behind that of their diurnal counterparts (Gaston, 2019), for me, these dark hours are, of course, full of life and diversity. Working with urban bats, I am not only fascinated by understanding which bat species live in the urban environment and why, I also like to think that knowing the bat species of a city tells us more about the nature that the city at night holds. Take Berlin, for example. Of the 25 bat species found in Germany, we have around 17 to 18 bat species here with different traits and needs. This tells us that Berlin offers a wide variety of habitats, not only for the more common urban species such as the noctule (<em>Nyctalus noctula<\/em>) or serotine bat (<em>Eptesicus serotinus<\/em>), but also for species such as Daubenton\u2019s (<em>Myotis daubentonii<\/em>) or the brown-long eared bat (<em>Plecotus auritus<\/em>), which have more specific requirements, broadly including water, trees, or dark areas. It is similar to Melbourne, where around 20 to 25 bat species are known. Here too, we find typical urban bat species such as Gould\u2019s\u202fwattled (<em>Chalinolobus gouldii<\/em>) or the white-striped free-tailed bat (<em>Austronomus australis<\/em>), but also the little forest bat (<em>Vespadelus vulturnus<\/em>), which, as the name suggests, relies on trees also within cities. So, protecting diverse urban habitats also means supporting a wide range of different bat species.<\/p>\n<p>However, not just the presence of nature or diverse urban habitats are important. Anthropogenic drivers impact these habitats, and one particularly significant driver for nocturnal biodiversity in cities is artificial light at night. But as we know, light is not just light. The <em>type <\/em>of lighting, <em>where <\/em>it is placed, and <em>when<\/em> it is used make a difference. We may sometimes see bats foraging around streetlights that attract insects. But in reality, only a few bat species can tolerate artificial light at night. For many bats, but also other nocturnal wildlife, lit areas are barriers. More attention and research are being given to what type of lighting is installed, where and when, whether through testing light spectrums that are less disruptive to both people and wildlife, sensor-based systems, or limiting light to areas where and when it is truly needed. However, while this knowledge is certainly important for biodiversity conservation, expert knowledge has now privileged over the perspective of local communities, who may support or oppose such strategies. This is where we need to think about cities as shared habitats, for both humans and wildlife, also at night.<\/p>\n<figure id=\"attachment_58254\" aria-describedby=\"caption-attachment-58254\" style=\"width: 604px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-58254\" src=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/20180826_Rauhautfledermaus_Pipistrellus-nathusii_Christian-Giese_DSC2201.jpg\" alt=\"A picture of a bat flying in the night, right toward the camera\" width=\"604\" height=\"403\" srcset=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/20180826_Rauhautfledermaus_Pipistrellus-nathusii_Christian-Giese_DSC2201.jpg 1920w, https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/20180826_Rauhautfledermaus_Pipistrellus-nathusii_Christian-Giese_DSC2201-839x560.jpg 839w, https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/20180826_Rauhautfledermaus_Pipistrellus-nathusii_Christian-Giese_DSC2201-1536x1026.jpg 1536w\" sizes=\"auto, (max-width: 604px) 100vw, 604px\" \/><figcaption id=\"caption-attachment-58254\" class=\"wp-caption-text\">Photo: Christian Giese<\/figcaption><\/figure>\n<p>An interesting example that comes to my mind is the River Severn corridor in Worcester, UK (Ferguson et al. 2023). Here, a collaborative project with different stakeholders transformed a brightly lit riverside path that was once a barrier for lesser horseshoe bats into a &#8220;shared space&#8221;. People continued to enjoy safe access into the city, and the bats returned, along with, quite possibly, other nocturnal wildlife. I like the idea of seeing bats as &#8220;nocturnal pandas&#8221;, umbrella species of the night whose protection helps safeguard vital ecosystems and many co-occurring species (Kalinkat et al., 2025). After all, by protecting dark islands and corridors in cities, implementing biodiversity-sensitive lighting, and engaging communities even when our focus begins with \u2018just\u2019 bats, we certainly also create opportunities for many other nocturnal species in urban areas.<\/p>\n<p>If you have not yet had the chance to experience bats in your city, I want to encourage you: go to a nearby waterbody on a warm summer night. Wait as the last warmth of the sun fades. Even without a bat detector, you might see the first bats fluttering around the vegetation at the water\u2019s edge or above the surface. And perhaps you will also feel that the nature of the dark hours in cities is not an absence of life, but just a different expression of it.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>References<\/strong><\/p>\n<p>Ferguson, J., Fox, H., Smith, N., Brookes, B., Vongpraseuth, M.,Levine, C., Morton, S., Miles, J., Harrison, P., Harding, G., Bolt, E., &amp; Howard, A.

What if urban lighting policies would not only acknowledge human needs but also the nocturnal lives of many other species unfolding around us?<\/blockquote><\/figure>\n<p><strong>The Unbearable Brightness of the Dark<\/strong><\/p>\n<p>For billions of years, life on Earth has evolved under the steady rhythm of day and night. This cycle of light and dark is one of the most ancient and universal environmental signals \u2014 a daily cue that has shaped the behaviour, physiology, and timing systems of all living organisms.<\/p>\n<p>Some species adapted to darkness to avoid predators; others evolved to take advantage of daylight for foraging or mating. Temperature also played a key role: early mammals, for example, became nocturnal to avoid daytime predators like dinosaurs. Because mammals could regulate their body temperature, they were able to remain active during the cooler nights. Reptiles, on the other hand, rely on external heat and typically need sunlight to warm up before they can move efficiently. Plants, too, anticipate and respond to the light-dark cycle: some open their flowers only at dawn, while others bloom at dusk to attract nocturnal pollinators. This temporal partitioning reduces competition. Even trees use changing day lengths to know when to grow or shed their leaves.<\/p>\n<p>But in just over a century \u2014 an evolutionary blink \u2014 humans have transformed the night. The invention of artificial lighting has allowed us to extend our activity into nighttime hours, pushing the boundaries of the natural day-night cycle, even though our biological clocks remain closely tied to it. Cities now glow deep into the night, enabling 24\/7 economies, social lives, and transportation systems. Light has become synonymous with progress, safety, and prosperity.<\/p>\n<p>Yet this brightness comes at a cost. Our internal biological clock with its 24-hour cycle (circadian rhythm) depends on natural light cues to regulate sleep, metabolism, hormone release, and immune function. Exposure to artificial light at night disrupts these natural clocks. Melatonin secretion, essential for the onset of sleep and nighttime restoration, is delayed. As a result, people may feel tired but find it hard to fall asleep. Over time, chronic circadian disruption increases the risk of sleep disorders, depression, obesity, and cardiovascular disease.<\/p>\n<p>Humans are not alone in this. Light pollution affects virtually all other species. Nocturnal animals may change their hunting or mating behaviors; migratory birds become disoriented; trees near streetlamps may keep their leaves longer, misreading the seasons. Darkness is not just the absence of light \u2014 it is a habitat, a condition many organisms depend on to survive and thrive.<\/p>\n<p>In our cities, the night is becoming a lost landscape. Instead of preserving the natural rhythm of light and dark, we have overwritten it with constant illumination. But what if we embraced darkness as a shared ecological space? What if urban lighting policies would not only acknowledge human needs but also the nocturnal lives of many other species unfolding around us?<\/p>\n<p>There is beauty and function in the dark. Moonlight, starlight, even the subtle glow of fireflies \u2014 these once defined the nighttime experience. By dimming our lights, we can restore not only the integrity of ecosystems, but also the visibility of the stars. And perhaps, rediscover a more humane pace of life.<\/p>\n<p>Cities that respect the night \u2014 through thoughtful lighting, darker zones, and public awareness \u2014 can lead the way in restoring this hidden half of our environment. Less light does not mean less safety or prosperity; on the contrary, it can foster greater well-being, biodiversity, and even economic resilience. It\u2019s about rebalancing our relationship with time, nature, and ourselves.<\/p>\n<p>Within the <strong>BioClock Consortium<\/strong>, researchers and societal partners from across the Netherlands have joined forces to restore and preserve the health of the biological clock.

As Indigenous people of the landscape that became New York City might have said, <em>xinkw n\u00ebw\u00ebmi,<\/em> the vast everything. Everything that became the landscape that became the city, including you and me and the shiny photons emitted from your screen, and the energy required for your fingers to click away, began with events some 13.7 billion years ago when the universe suddenly, and for its own reasons, sprang into being: the so-called Big Bang. Everything since\u2015the moon, the stars, the Earth, your city, my city, you and me\u2015is just an elaboration of those primordial potentials into forms and the inherent and resistance of those forms to the inevitable dissolution into a low, universal hum.<\/p>\n<p>What would one see? I like to imagine the evening of September 11, 1609, on the eve of New York\u2019s colonization, by all accounts a clear, cloud-free day, when climbing a tree in lower <em>Mannahatta<\/em> or paddling out among the waves in the most beautiful harbor of the world, one could turn one\u2019s face upward to see the events of the great beginning. Astronomers tell us that some 300-400 million years after the Big Bang, the first stars collected enough mass to ignite on the distant horizon, and the first stars flamed into being. Stars like people burn, grow, and die, and collections of those stars, and their children and grandchildren, aggregated to form our galaxy when the universe was about 8.7 billion years old. Out on one arm of the many-armed spiral galaxy (the Milky Way), our solar system would eventually coalesce, a tiny instance of the universal story.<\/p>\n<p>Our Sun, a star, caught flame around 4.5 billion years ago. The Earth at your feet formed from dust too far out to get sucked into the Sun, but too close to fly away. Ours is the fortunate planet, near enough to receive enough warmth that water is liquid on the surface, but not so much warmth that all water boils away. The first billion years after formation were rough going, with multiple meteor strikes, massive volcanoes, molten seas, and little to no atmosphere. The Moon is thought to be a chunk of the Earth disgorged after one such massive collision. Such collisions gave the Earth a tilt that gives us seasons. The pull of the Moon generates the tides. The heat of the furious bombardments of the early days remains trapped inside the planet\u2019s core, where it generates a protective magnetic field, causes slight but significant wobbles in the Earth\u2019s orbit that change the climate, fuels volcanoes, and enables plate tectonics. The land, the water, and the sky on the surface reflect in ways both large and small what is happening deep inside.<\/p>\n<p>One of the more curious consequences of the random bumps and accidents of the physical universe is the generation of life. On Earth, life emerged around 3.7 billion years ago, possibly earlier, possibly multiple times, which suggests it also failed multiple times. The evolution of photosynthesis by cyanobacteria resulted in a waste product, oxygen gas. The Great Oxidation Event of 2.4 billion years ago set the stage for eukaryotic life (cells with substructures called organelles) using aerobic respiration which evolved around 1.85 billion years ago. Multi-cellular organisms are about 1.7 billion years old; plants, which evolved from green algae, are about one billion years old; the earliest animals, sponges, and comb jellies are about 750 million years old; the first vertebrates (fish) about 480 million years old; the earliest land plants about 470 million years old; the earliest Humans (<em>Homo sapiens<\/em>), our ancestors, differentiated from their hominin kin only about 300,000\u2015400,000 years ago. It was only a mere 80,000 years ago that they left Africa to wander the rest of the continents. Only 10,000 years ago (give or take), did people arrive in <em>Welikia<\/em> (my name for the landscape before New York City), around the same time first proto-cities were developing near the early agriculture fields half a world away.<\/p>\n<p>What do we miss not seeing the stars above our cities?

De donkere uren vormen geen leegte of pauze tot het weer licht wordt. Voor veel nachtdieren begint juist dan hun actieve deel van de dag. Denk aan egels, uilen, nachtvlinders en zeker ook aan vleermuizen. In Europese steden kun je ongeveer een tiental soorten vleermuizen tegenkomen, waaronder de gewone, ruige of kleine dwergvleermuis (<em>Pipistrellus pipistrellus, P. nathusii, P. pygmaeus<\/em>) en de laatvlieger (<em>Eptesicus serotinus<\/em>). Ze jagen op insecten boven vijvers en in tuinen, volgen boomrijen tussen flats en vinden hun verblijfplaatsen in gebouwen. Ze slapen, overwinteren, paren of brengen hun jongen groot op kerkzolders, achter gevelbetimmering, onder dakpannen of in de spouwmuur. Vleermuizen zijn echt fascinerend. Ze zijn de enige zoogdieren op aarde die actief kunnen vliegen en gebruiken echolocatie om te jagen en zich te ori\u00ebnteren. Dankzij hun winterslaap en effici\u00ebnte DNA-herstelmechanisme worden ze uitzonderlijk oud voor hun formaat.<\/p>\n<figure id=\"attachment_58199\" aria-describedby=\"caption-attachment-58199\" style=\"width: 604px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-58199\" src=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/3.-Gewone-dwergvleermuis-foto-Rene-Janssen-scaled.jpg\" alt=\"A picture of a bat flying at night\" width=\"604\" height=\"401\" srcset=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/3.-Gewone-dwergvleermuis-foto-Rene-Janssen-scaled.jpg 2560w, https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/3.-Gewone-dwergvleermuis-foto-Rene-Janssen-843x560.jpg 843w, https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/3.-Gewone-dwergvleermuis-foto-Rene-Janssen-1536x1020.jpg 1536w, https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/3.-Gewone-dwergvleermuis-foto-Rene-Janssen-2048x1360.jpg 2048w\" sizes=\"auto, (max-width: 604px) 100vw, 604px\" \/><figcaption id=\"caption-attachment-58199\" class=\"wp-caption-text\">Gewone Dwergvleermuis, Common Pipistrelle.

Niet alleen functioneel (vleermuizen eten veel insecten, helaas minder steekmuggen dan vaak wordt geschreven in populaire artikelen), maar vooral intrinsiek. De waarde van een dier afmeten aan zijn nut voor de mens getuigt van een antropocentrische blik. Als sleutelsoort van de stad zouden wij juist moeten leren om de waarde van wilde dieren en planten op zichzelf te zien. Wij zijn onderdeel van de biodiversiteit, niet het middelpunt ervan.<\/p>\n<p>Tegelijk verandert het nachtleven razendsnel. Waar natuurlijke duisternis ooit vanzelfsprekend was, is ze in steden grotendeels verdwenen. Kunstlicht was ooit schaars en kostbaar, maar met de introductie van elektrische straatverlichting vanaf begin 1900, en sinds 2000 vooral ledverlichting, is licht alomtegenwoordig. Ironisch genoeg heeft die effici\u00ebntie van led geleid tot m\u00e9\u00e9r licht, niet minder. Wereldwijd neemt nachtelijke kunstverlichting (ook wel ALAN genoemd: <em>artificial light at night<\/em>) jaarlijks met een verontrustende 2\u20136% toe. In grote delen van West-Europa is de Melkweg inmiddels niet meer zichtbaar. De stedelijke hemel wordt steeds blauwer door de korte golflengtes van witte leds die rijk zijn aan UV, waarop veel dieren sterk reageren.<\/p>\n<figure id=\"attachment_58201\" aria-describedby=\"caption-attachment-58201\" style=\"width: 604px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-58201\" src=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/The_Netherlands_by_night-by-ESA-NASA-free-to-use-with-name.jpg\" alt=\"An aerial photo of a city at night.

Dat is veel meer dan nodig is voor veiligheid of zicht. Voor veel vleermuizen betekent dit dat zij routes, drinkplaatsen en jachtgebieden mijden. Insecten worden massaal aangetrokken door lampen, raken uitgeput, sterven, en verdwijnen uit de voedselketen. Ook mensen ervaren negatieve effecten: verstoorde slaap, verhoogde stress en het verlies van sterrenlicht.<\/p>\n<p>Gelukkig ontstaan er hoopvolle tegenbewegingen. In steden als Den Haag, Ljubljana en Bonn zijn zones ingesteld waar de nacht weer donker mag zijn: \u2018donkere ecologische corridors\u2019 zonder straatverlichting of met dynamische of aangepaste amberkleurige lampen. Deze verlichting houdt rekening met zowel menselijke veiligheid als ecologische behoeften.

The dark hours are not a pause or void before daylight returns\u2014they are, for many nocturnal species, the true beginning of their day. Think of hedgehogs, owls, moths, and especially bats. In European cities, you can encounter around ten bat species, including the common, Nathusius\u2019, and soprano pipistrelle (<em>Pipistrellus pipistrellus, P. nathusii, P. pygmaeus<\/em>) as well as the serotine bat (<em>Eptesicus serotinus<\/em>). They hunt insects above ponds and gardens, navigate tree-lined avenues between apartment blocks, and roost in our buildings. They sleep, hibernate, mate, or raise their young in church attics, behind fa\u00e7ades, under roof tiles, or inside cavity walls.<\/p>\n<p>Bats are truly fascinating. They\u2019re the only mammals capable of true flight and use echolocation to hunt and orient themselves. Thanks to their ability to hibernate and an efficient DNA repair system, they can live remarkably long lives for such small mammals.<\/p>\n<figure id=\"attachment_58199\" aria-describedby=\"caption-attachment-58199\" style=\"width: 604px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-58199\" src=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/3.-Gewone-dwergvleermuis-foto-Rene-Janssen-scaled.jpg\" alt=\"A picture of a bat flying at night\" width=\"604\" height=\"401\" srcset=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/3.-Gewone-dwergvleermuis-foto-Rene-Janssen-scaled.jpg 2560w, https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/3.-Gewone-dwergvleermuis-foto-Rene-Janssen-843x560.jpg 843w, https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/3.-Gewone-dwergvleermuis-foto-Rene-Janssen-1536x1020.jpg 1536w, https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/3.-Gewone-dwergvleermuis-foto-Rene-Janssen-2048x1360.jpg 2048w\" sizes=\"auto, (max-width: 604px) 100vw, 604px\" \/><figcaption id=\"caption-attachment-58199\" class=\"wp-caption-text\">Gewone Dwergvleermuis, Common Pipistrelle.

As the dominant species in the urban ecosystem, we should learn to see wild plants and animals as valuable in their own right. We are part of urban biodiversity\u2014not its center.<\/p>\n<p>At the same time, urban nightscapes are changing rapidly. Where natural darkness was once a given, it has now almost vanished from city life. Artificial light was once rare and expensive, but with the introduction of electric streetlights in the early 1900s\u2014and since 2000, a rapid rise in LED lighting\u2014light is now everywhere. Ironically, LED\u2019s efficiency has led to more lighting, not less. Globally, artificial light at night (ALAN) is increasing by an alarming 2\u20136% per year. In much of Western Europe, the Milky Way is no longer visible. Urban night skies are increasingly blue due to the short wavelengths and UV-rich spectrum of white LEDs\u2014something to which many animals are particularly sensitive.<\/p>\n<figure id=\"attachment_58201\" aria-describedby=\"caption-attachment-58201\" style=\"width: 604px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-58201\" src=\"https:\/\/www.thenatureofcities.com\/TNOC\/wp-content\/uploads\/2025\/06\/The_Netherlands_by_night-by-ESA-NASA-free-to-use-with-name.jpg\" alt=\"An aerial photo of a city at night.

That\u2019s far more than needed for safety or visibility. For many bat species, this level of brightness means avoiding vital routes, drinking sites, and foraging areas. Insects are drawn in large numbers to lamps, where they exhaust themselves, die, and drop out of the food chain. People, too, suffer from disrupted sleep, increased stress, and the loss of natural darkness.<\/p>\n<p>Thankfully, hopeful counter-movements are emerging. In cities like The Hague, Ljubljana, and Bonn, zones have been created where darkness is preserved: \u201cdark ecological corridors\u201d with no streetlights, or with dynamic, low-intensity amber lighting that responds to both human use and ecological needs.
