Special thanks to @bardseybirdobs.bsky.social and @copelandbirdobs.bsky.social for their incredible support and being wonderful places to spend time with Manx shearwaters! Thanks also to project SHEAR and my brilliant co-author team!

We enjoyed thinking about how being both wind-efficient and target-oriented might together help shape colony foraging ranges...
If birds learn their foraging landscape over time, but prevailing winds influence where they get to know best, windscape effects should persist even on calm days

We estimated flight costs under different wind conditions using accelerometry and measured the wind selectivity of shearwater flight decisions - did they choose the cheapest available path given the wind, or were they prioritising something else?

Manx shearwaters seem to fall somewhere in between - they show some evidence of targeted foraging movements, but have a strong preference for flying in a crosswind direction for dynamic soaring
So how does a seabird both wind-efficient and target-oriented make foraging decisions?

New paper in @currentbiology.bsky.social on seabird wind use and foraging decisions!

We estimated wind selectivity in Manx shearwaters and explored how birds handle the trade-off between being wind efficient and targeting known foraging areas
