📡 Why do Martins and Swallows pass by the Great Lakes when they do - Great collaboration with Yuting Deng and @kyle-horton.bsky.social. @biodiversa.eu 📡

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....

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.

These are 5 autumn migration routes travelled by the same common tern. He’s not the only one showing such flexibility, and it pays, because in our new paper, published by @royalsocietypublishing.org, we show that route flexibility is associated with minimized headwind exposure: tinyurl.com/4dawhwzj

Our @batumiraptorcount.org Autumn Report is now online!

Ever considered coming to Batumi to watch the incredible migration of 1+ million raptors 🦅, either as tourist or volunteer? Let our richly illustrated reports convince you to come next year.

A male Pallid Harrier giving impeccable views as it rapidly passed the count station. The bird shows its characteristic almost black-and-white plumage with the thin black wedge at the wingtips, and stands out clearly against the dark backdrop of the Batumi bottleneck.

Wondering why acoustic indices may also correlate with diversity metrics of non-vocalizing species?

Check out our new paper led by @saskiadroege.bsky.social with acoustic, habitat quality, and multi-taxa biodiversity data from northeastern Madagascar!
