What an epic return! 🤩🌍🐦

A common snipe tagged in April 2025 near Olomouc is back in Czechia after migrating to the Yamalo-Nenets AO (east of the Urals) – a round trip of over 7,500 km!

However, private allelic richness declined slightly with latitude, showing that even with high dispersal, some genetic footprint remains.
Combining all evidence revealed the expansion origin in the SW of the range. 4/6

There was no drop in nucleotide diversity or allelic richness across the expansion front and almost no founder effect signals. This suggests that high dispersal capacity buffered against the usual genetic costs. 3/6

Here, we combined historical observations on first occurrences, ring recovery data and genomic analyses spanning the European breeding range to map the expansion and to test its genetic consequences. 2/6

Our new study in Molecular Ecology doi.org/10.1111/mec.... explores the northward expansion of the Eurasian #reedwarbler. Despite a fast range shift, genetic diversity wasn't lost and only weak founder effect signs were found. Let’s break it down: 🧵👇 1/6

The first six tagged Turtle Doves are back in Europe and have sent the data from their African non-breeding sites! 🤩

This winter we newly ringed 44 Black Redstarts and resighted/retrapped 14 from previous winters. Just a casual winter monitoring project in Brno, but one that is truly close to my heart! ❤️ The aim is to study survival, within-winter movements and where the birds breed. | #BrnoRedstart #BlackRedstart

Hi Alex, I have absolutely no idea - just found this useless curiosity... 😅
