**Global Study Reveals Light Pollution Disrupts Bird Behavior, Extending Activity by Nearly an Hour**
**CHENNAI, September 16, 2025** – A groundbreaking global study has revealed the significant impact of artificial light on bird behavior, stretching their active hours by nearly an hour after sundown. The research, analyzing over 60 million bird vocalizations from 583 species worldwide, highlights the disruptive effects of light pollution on avian ecosystems.
The study, led by Dr. Brent Pease from Southern Illinois University Carbondale, and co-authored by Neil Gilbert, Oklahoma State University, leveraged a volunteer-powered acoustic network called BirdWeather, utilizing AI (BirdNET) to analyze bird songs across continents. Researchers compared bird activity in brightly lit areas with that in darker areas, focusing on sunrise and sunset song times, eye size, nesting habits, migration patterns, and habitat types.
“We were pretty surprised by the size of the effect,” Gilbert said. “Fifty minutes as an average across species was quite a bit more than what we were expecting.”
**Key Findings:**
* **Extended Activity:** Birds in brightly lit areas remain active nearly an hour longer each day.
* **Species Variability:** Birds with larger eyes and open-nesting habits are more affected by artificial light. Migratory birds are also more unsettled than stay-at-home species.
* **Disrupted Rhythms:** Light pollution disrupts natural avian rhythms, potentially impacting migration, feeding, breeding and ecological balance.
According to Anusha Shankar, Tata Institute of Fundamental Research, light pollution disrupts natural time keeping mechanisms which may have devastating effects on migratory birds.
**Impact on Ecosystems:**
Scientists warn that this artificial extension of the day can disrupt vital biological processes. For instance, birds rely on seasonal light cues to time their migrations to coincide with food sources. Changes in plant flowering or insect hatching due to light pollution could create perilous mismatches for these migratory birds.
Filmmaker Sriram Murali warned that light pollution affects the circadian rhythm, and that if artificial lighting affects humans then so should it also be a matter of concern for animals.
**The Indian Perspective:**
In India, the effects of light pollution are already being observed. Birds are increasingly colliding with brightly lit glass facades in urban areas, turning buildings into deadly traps. The plight of fireflies, which rely on bioluminescent flashes to attract mates, is also exacerbated by artificial light, hindering their communication and survival.
**A Reversible Problem:**
Unlike other environmental issues, light pollution is readily reversible. The study emphasizes that simple solutions like shielding streetlamps, dimming billboards, and switching off unnecessary lights can make a significant difference.
“If light pollution turns out to be a negative thing for bird populations, we can do a behavior change across the globe to turn out the lights and make the night dark again,” Dr. Pease said. “We’re just a light switch away here.”
This research underscores the need for greater awareness and responsible lighting practices to protect avian ecosystems and preserve the natural rhythms of the night.
**Summary of the text:**
A global study using AI and volunteer-collected bird vocalizations has found that light pollution is causing birds to stay active nearly an hour longer each day. This disruption impacts their natural rhythms, potentially affecting migration, feeding, and breeding. The impact varies by species, with those having larger eyes and open-nesting habits being more affected. In India, this is seen in bird collisions with buildings and disrupted firefly communication. Unlike other environmental issues, light pollution is easily reversible by reducing unnecessary lighting.
