It's been a busy summer for our scientists. Several of them attended the #ESEB2025 conference in Barcelona.

Another paper from the lab, this time using very long time series of our flycatcher data.

Stay away from the vortex ;) #fieldwork day 19th during the 2025 season of the #gotland bird project :)

We’re piloting a new study - looking at aesthetic tastes of blue tits, and possibly visual style copying behaviour. Today we distributed artificial bird bodies (mimicking the usual source of feathers for BTs - dead birds and leftover feathers). We used feathers of peacocks, Japanese quails and

We are starting our new season #gotland2025 - with warm weather, birds already starting first nests, and a visit to a changed Fide Odvalds plot (see photo: they cut down some of the densest parts, in efforts (as I was told) to eradicate invasive Rubus species…). The highlight of today:
