Truly impressive number of birds migrating tonight. More than 800 MILLION birds up in the air right now❗ #BirdMigration

Tonight’s forecast: 304 million birds expected to migrate across the U.S. 🕊️📡 The Upper Midwest is especially active – keep an eye on the skies and consider going “Lights Out” to help reduce risks for nocturnal migrants. #BirdMigration #LightsOut #Midwest

🚨 Tuesday 19 10:30 #EOU2025 Come and join us for the symposium on #bird #migration and #ALAN, aiming to discuss fundamental research and policy. @baptischmi.bsky.social @carburt.bsky.social @jlyr.bsky.social @vogelwarte.bsky.social #ornithology #aeroecology #movementecology #lightpollution

Still in awe of these experiences. The sounds, the dances, and the drama! Nothing like watching these leks up close.

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.

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

Awesome turnout at the #marchforscience today! @indivisible.org @indivisible-co.bsky.social @coloradosun.com @nytimes.com @bennet.senate.gov @neguse.house.gov

We all need a space to feel we belong and where we are supported. Help our Flocks take flight! Support our joint effort with @wilsonornithsoc.bsky.social & @fieldornith.bsky.social! Every bit of help makes a difference. gofund.me/b82daffb

Please share with your birdy and ornithology connections. My summer Field Ornithology course is open for enrollment. We live and study birds on an island in Maine for two weeks!!! DM me with any questions. #ornithology

Excited this paper is out as part of our NSF project to create technological advances to move toward sustainable lighting policies with @kyle-horton.bsky.social and Jeff Kelly! New improved bird migration forecasts led by @mikkojimenez.bsky.social and Ali Khalighifar.
