Sadly, the remains of M0 were found there on 16 Feb 2026 (likely taken by a domestic 😼).
Still, the record is very valuable: it shows that some Black Redstarts wintering in Czechia can move hundreds of km within the same winter.
👀 If you see a colour-ringed bird, please report it! 🙏
One bird, L5, was seen again at the same place on 20 Feb 2026.
But M0 seemed to have vanished completely — until an unexpected report arrived from Austria!
The bird had travelled 382 km southwest of Brno to the Alpine village of Iselsberg (East Tyrol). 🧵👇
A winter journey from Brno to the Alps 🐦⛰️
On 2 Dec 2025, we colour-ringed two young Black Redstarts at a brownfield site in Brno (Czechia): L5 and M0.
Both birds disappeared soon afterwards.
Then something unexpected happened… 🧵👇

🐦📡 The male woodcock Xixao from the Brdy Mountains is back. Until the end of February he stayed in the forests of Normandy 🇫🇷.
He started his migration on Feb 28, which took him 4 nights, flying each evening from 18:00 until after 2:00 a.m. 🌙

How does a single cuckoo species evolve eggs that mimic those of many different hosts?
In a new Science study, researchers report genomic data that reveal a complex geographic mosaic of cuckoo-host coevolution.
