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.

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.

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).
