Photometrics AI Integrates Data from Bird Migration Forecasts to Automatically Dim Streetlights

SAN DIEGO - Feb. 10, 2026 - PRLog -- SAN DIEGO, CA — Bright lights lead to the deaths of countless migrating birds each fall and spring, when millions stream across the night sky. Lights disorient birds and draws them closer to buildings where they collide with windows. A new AI technology protects them by automatically dimming lights when it matters most.

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's BirdCast migration monitoring platform signals big migration nights with high risks for window collisions.

"Street lighting represents one of the largest sources of artificial light at night in urban areas," said Ari Isaak, founder of Photometrics AI. "By connecting our optimization platform to BirdCast's real-time migration data, cities can take meaningful conservation action that runs automatically—not as a one-time campaign, but as an ongoing operational capability."

How It Works

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.

Photometrics AI'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.

Because more than half of annual nocturnal bird migration over the contiguous U.S. occurs on just 10% of nights (https://conbio.onlinelibrary.wiley.com/doi/pdf/10.1111/co...), targeted lighting reduction during peak events is a dynamic and high-impact conservation strategy. 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.

"Dimming the lights when and where the streets aren't being used makes a big difference for birds, but it makes almost no difference for us," Isaak said. "This 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."
