New paper! We simulated foraging trips of Northern gannets at Bass Rock to decipher what information individuals use to keep returning to the same foraging patches. Memory was the strongest driver, but it wasn't the whole story. 🧵👇 doi.org/10.1186/s404... 1/5

Lesser black-backed gulls avoid offshore wind farms - but not because they are attracted by the fishing boats outside of those windfarms New article on #seabirds #ornithology besjournals.onlinelibrary.wiley.com/doi/10.1111/... @robvanbemmelen.bsky.social, @judyshamounb.bsky.social

Offshore wind farm avoidance by a discard‐feeding seabird is independent of local fishing activity

Fishing is not allowed within wind farms; therefore, discard-feeding seabirds may appear to avoid wind farm areas. We found that most Lesser Black-backed Gulls avoided the wind farm area, but not eac....

Peatlands occupy just 3% of all land but contain more carbon than all of the world’s forests. Often overlooked: typically flat, wet, often inaccessible, not always picturesque & all the carbon they hold is hiding below the surface. 80% of the UK bogs are degraded by draining, overgrazing, burning.

Sobering. When I talk to people about long-term bird population declines in N America, I mention that the main cause is habitat loss, not climate change - yet. But new research shows that climate change is causing bird declines even in otherwise pristine places. www.theguardian.com/environment/...
