Some migration info from 7 Whinchats (Saxicola rubetra) tagged with multi-sensor loggers: kind of loop migration, spring Sahara crossing up to ~5,000 m despite their tiny size (~16g), and unusually prolonged flights both at autumn and spring. 🪶🏔️ Full paper here: doi.org/10.1007/s10336-026-02409-1

Ongoing winter weather and frozen waters still pushes Caspian Gulls into Potsdam's city centre.

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. Watch this: youtu.be/MY4mbE_fQ4Y?... Water Pipits, Saxony, Germany.

Finding something like that in Germany... #dreambird

Eastern Lesser Whitethroat caught two days ago on the Island of Greifswalder Oie, Germany. Length of P2, sandy colouration and mainly whitish T6 points to halimodendri. Bird expertly handled and ringed under licence.

Ménétries's Warbler in Poland this spring. DNA work by @tessaroo.bsky.social

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. www.birds.org.il/en/article/S...

Short clip of the ocularis type Wagtail. www.youtube.com/watch?v=AHOn...

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

Few shots from yesterday's Gull and ring reading tour in Potsdam, Germany.
