Combining weather radar data with environmental data, @birgenhaest.bsky.social and co-authors found that peak roosting phenology of migrating martins and swallows in the Great Lakes region is paced by both local and distant conditions. Read more on doi.org/10.1111/geb....

Lights Out alert map for the U.S. showing almost all the states in some level of needing lights out for birds.

Lots of Lights Out alerts tonight as we come into the mad rush that is Maygration.

The birds won’t disappoint!

Spring is for the grouse and chickens! Colorado leks have been 🔥🔥🔥 (w/@carburt.bsky.social). Greater Sage-Grouse and Greater Prairie-Chickens 📷

Birds will be arriving soon! This map shows peak migration dates across the US modeled using radar data. Keep in mind, the dates represent peaks, but migration usually plays out across a couple of weeks, so estimate ± 1 week on either side of the dates on the map for max migration activity.

Weather radars continuously register the movements of billions of animals in the air! We have now published datasets covering large parts of Europe, providing an overview of the aerial habitat in a way no other method can.

Data is available on Alofdata.eu , see our blogpost:

Summary text of the planned EOU symposium (Bangor, Wales UK, 18-22 August 2025): Artificial light at night (ALAN) can drastically alter the environment of migratory birds, both on their breeding grounds, non-breeding grounds and during their migratory journeys. ALAN can therefore disrupt the birds' evolved response to natural changes in environmental light. For example, light is an important cue for determining the circa-annual cycle of birds, and birds use it to orientate during their migratory flights. The scale of the problem has been recognised by the Bonn Convention on Migratory Species (CMS), which aims to identify knowledge gaps and develop guidelines to reduce the impact of light pollution on migratory species. This symposium aims to present the latest research on the effects of ALAN on migratory birds, identify research gaps, and to improve our understanding of how to adapt research projects in order to translate research results into policy and legislation.

Happy to co-organise a symposium on migratory birds and artificial light at night: from research to policy. #ornithology #aeroecology submit 👆🏽your abstract before March 15 😀 #eou2025

Abstracts for #AOS25 Oral Presentations & Posters are due by 3/16/25. Share your research. The submission form includes a set of questions for those who want to be considered for the Student Presentation Award competition! meeting.americanornithology.org/call-for-abs...
