Footprint of state border infrastructure extends beyond the border: Tree damage and roadkill along a road in Białowieża Forest, northeastern Poland
State border barriers are proliferating, but their ecological impacts are poorly documented, particularly during construction. More than 50 km of Pola…

An extremely rare pygmy shrew with a leucistic mutation was found by Anita McMillan near St Austell, Cornwall.
CEO of the @mammalsociety.bsky.social, @mattlarsen-daw.bsky.social, states it's the first pygmy shrew with this distinctive patterning ever recorded in the British Isles.

Rampaging raccoons: how the American mammals took over a German city – and are heading across Europe
Many in Kassel have embraced the animal but the EU classes it as an invasive species and ecologists are divided about what to do next

Absolute carnage in the Białowieża Wood Warbler study this year. Nest failure rate currently running at over 83%!!!! Almost all due to predation: mostly foxes, jays and martens. Some also trampled, possibly Red Deer. Only a handful of nests have fledged any chicks. @martamaziarz.bsky.social

Kestrel activity levels were lower while use of patches with trees increased with temperature. Temperature thresholds above which activity declines varied with time of day, and at higher temperatures, usage of trees was more frequent between 11am and 4pm. 4/5
