Lights disorient birds and draws them closer to buildings where they collide with windows. A new AI technology&nbsp; protects them by automatically dimming lights when it matters most.<\/p>\n\n\n\n<p>Photometrics AI, a street-lighting optimization company, now includes bird migration forecasts as part of its lighting management platform. Cities using the platform will have access to an automated feature that dims lights when data from the Cornell Lab of Ornithology\u2019s BirdCast migration monitoring platform signals big migration nights with high risks for window collisions.<\/p>\n\n\n<div class=\"article-list alignright right list-style card-four \"><h2 class=\"article-list-header\">More Cornell Lab News<\/h2><ul><li class=\"article-item\"><div class=\"article-item-container\"><div class=\"article-item-media content-article\" data-link-to=\"https:\/\/www.birds.cornell.edu\/home\/news\/\"><figure class=\"article-item-media-ratio\"><img decoding=\"async\" src=\"https:\/\/www.birds.cornell.edu\/home\/wp-content\/uploads\/2025\/02\/YellowBelliedSapsucker_StevenHunter.jpeg\" srcset=\"https:\/\/www.birds.cornell.edu\/home\/wp-content\/uploads\/2025\/02\/YellowBelliedSapsucker_StevenHunter-720x527.jpeg 720w, https:\/\/www.birds.cornell.edu\/home\/wp-content\/uploads\/2025\/02\/YellowBelliedSapsucker_StevenHunter-768x563.jpeg 768w, https:\/\/www.birds.cornell.edu\/home\/wp-content\/uploads\/2025\/02\/YellowBelliedSapsucker_StevenHunter-480x352.jpeg 480w, https:\/\/www.birds.cornell.edu\/home\/wp-content\/uploads\/2025\/02\/YellowBelliedSapsucker_StevenHunter.jpeg 1200w\" sizes=\"\" alt=\"\" loading=\"lazy\" \/><\/figure><\/div><div class=\"article-item-body\"><a class=\"article-item-link\" href=\"https:\/\/www.birds.cornell.edu\/home\/news\/\"><span class=\"article-item-header\">News Room<\/span><\/a><\/div><\/div><\/li><\/ul><\/div>\n\n\n<p>&#8220;Street lighting represents one of the largest sources of artificial light at night in urban areas,&#8221; said Ari Isaak, founder of Photometrics AI. &#8220;By connecting our optimization platform to BirdCast&#8217;s real-time migration data, cities can take meaningful conservation action that runs automatically\u2014not as a one-time campaign, but as an ongoing operational capability.&#8221;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How It Works<\/h2>\n\n\n\n<p>BirdCast is a collaborative project among researchers at the Cornell Lab of Ornithology, Purdue University, University of Illinois Urbana-Champaign, and University of Massachusetts Amherst. BirdCast uses weather radar to detect the number of birds aloft. It produces nightly forecasts of migration intensity, up to three days in advance, for the period approximately three hours after local sunset. BirdCast also provides data in a dashboard depicting intensity, flight direction, speed, altitude, and nightly and seasonal timing of nocturnal migration. The forecast data are also used to create alerts when migration intensity reaches significant levels.<\/p>\n\n\n\n<p>Photometrics AI&#8217;s platform can receive these forecasts and use them to automatically adjust streetlights on nights when bird migration is heaviest. The system is designed to keep main roads, crosswalks, and other high-traffic areas safely lit, while dimming lights in residential zones and open spaces.&nbsp;<\/p>\n\n\n\n<p>Because <a href=\"https:\/\/conbio.onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/cobi.13740\">more than half of annual nocturnal bird migration over the contiguous U.S. occurs on just 10% of nights, targeted lighting reduction during peak events is a dynamic and high-impact conservation strategy<\/a>. The biggest impact comes from reducing lights late at night and in the early morning, when birds fly at their lowest altitudes and humans need bright light the least.<\/p>\n\n\n\n<p>\u201cDimming the lights when and where the streets aren\u2019t being used makes a big difference for birds, but it makes almost no difference for us,\u201d Isaak said. \u201cThis technology allows us to use lighting as effectively as possible so that we can live alongside the other creatures and species that we share the space with.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why It Matters<\/h2>\n\n\n\n<p>Each year, <a href=\"https:\/\/journals.plos.org\/plosone\/article?id=10.1371\/journal.pone.0306362\">more than 1 billion birds die in the U.S. from collisions with buildings and windows<\/a>. Bright city lights disorient migrating birds, pulling them toward urban areas and putting them in close proximity to structures where collisions can be deadly, including residential homes, corporate and university campuses, skyscrapers, greenhouses, and glass-enclosed bus stops.&nbsp;<\/p>\n\n\n\n<p>The problem of light pollution is accelerating. According to research published in <em>Science<\/em>, <a href=\"https:\/\/www.science.org\/doi\/10.1126\/science.abq7781\">night skies are growing brighter by nearly 10% each year<\/a>. For many people, the night sky today is twice as bright as it was eight years ago. The brighter the sky, the greater the negative impacts on birds\u2019 senses, and the fewer stars visible for orientation and navigation. \u201cLight pollution that conflicts with birds\u2019 sensory capabilities, themselves, and with the visibility of stars that birds use as cues to orient and to navigate makes nocturnal migration significantly more difficult and dangerous for many species,\u201d says Andrew Farnsworth, one of BirdCast\u2019s scientists at the Cornell Lab of Ornithology. \u201cEliminating this conflict, whenever and wherever we can, is a conservation win.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">About Photometrics AI<\/h2>\n\n\n\n<p>Photometrics AI develops software that optimizes street lighting performance through networked lighting controls.
