Ongoing winter weather and frozen waters still pushes Caspian Gulls into Potsdam's city centre.
Great photos! Haven't seen pictures of a second-winter RBG in our latitudes for a while.
Happy to share our new paper published in @cp-iscience.bsky.social We deployed 300+ multi-sensor loggers across 17 species to investigate how different species adapt their flight strategies when crossing deserts and marine areas during migration. tinyurl.com/2c8y8xvf #ornithology #birds
Spend a few hours with these little fellows and you’ll be amazed at how effortlessly they find invertebrates in a recently drained pond.

Barred Warber (Curruca nisoria) in flight.
Spotted a Barred Warbler with a metal ring near my hometown last month — just found out it was originally ringed in Israel. Amazing to think how far it’s traveled! You can read the full story on the BirdLife Israel website.

Hi Alan,
as you said adult males should show more white in the GC but I'm not sure about the sex and age so far, sure it's not a 1st winter.
Furthermore I find it quite easy to spot photos from Hong Kong, Russia, Taiwan or Alaska with similar/same wing panels, even with less white in GC.

Found this interesting looking Wagtail in a flock of ca. 60 White Wagtails today at Pareyer Luch, Eastern Germany. It showed a complete eye stripe on both side of head and looks quite promising to be an East Siberian Wagtail (ocularis).

We have just returned from La Janda, S Spain, where we sampled some of the wintering Siberian buntings (1 Rustic, 5 Little Buntings) to uncover their birth/breeding origins. Huge thanks to the Cigüeña Negra ringing group for the warm welcome! @pdvsky.bsky.social #ornithology
