Aeroeco Lab

 

Welcome to the Colorado State University Aeroecology Lab in the Department of Fish, Wildlife, and Conservation Biology. We study bird, bat, and insect migration using a range of tools and approaches, including the use of radar, acoustics, and citizen science data. Our work addresses a handful of core migration questions, including avian flight strategies, long-term phenological change, population estimates, impacts of artificial light, and migration forecasting.

 

New to the website: Lights out alerts

We now have live updates of where and when to turn off lights through the spring and fall migration seasons. We hope they’ll be useful to the bird conservation community. Please use the materials as needed.

Bright lights in the big cities: migratory birds’ exposure to artificial light. (Frontiers in Ecology and the Environment 2019). 🔗

Abstract: Many species of migratory birds have evolved the ability to migrate at night, and the recent and rapid expansion of artificial light at night has markedly altered the nighttime sky through which they travel. Migrating birds regularly pass through heavily illuminated landscapes, and bright lights affect avian orientation. But risks to migrating birds from artificial light are not spatially or temporally uniform, representing a challenge for mitigating potential hazards and developing action plans to catalog risks at continental scales. We leveraged over two decades of remote-sensing data collected by weather surveillance radar and satellite-based sensors to identify locations and times of year when the highest numbers of migrating birds are exposed to light pollution in the contiguous US. Our continental-scale quantification of light exposure provides a novel opportunity for dynamic and targeted conservation strategies to address the hazards posed by light pollution to nocturnally migrating birds.
