Foreign aid contributions fell in 2025 amongst almost all of the top 10 donors. In 2025, the amount of foreign aid given by the world’s richest countries fell by almost a quarter. That amounted to a reduction of roughly US$50 billion.

New paper in @animalecology.bsky.social!📝http://doi.org/10.1111/1365-2656.70350 Coordination is thought to be key to the success of biparental care, but we don’t know how this varies with species’ ecology 🍃 We explore: how important is partner coordination & does this depend on environment? 🏞️

Always great to help with a colour-ringing project! We ringed an extra 3 LBBG in Liverpool today (!), likely the last ones we'll catch here this summer. Keep an eye out for green colour-ringed gulls & report any sightings at nwgulls.org.uk 💍 #seabirds #ornithology @joewynnbirds.bsky.social

Two out of the (only) three White-tailed Eagles fledged in England in 2025 have since 'disappeared in suspicious circumstances', i.e. people killed them within months. Read this, and see how much effort those people go to, to kill them. We all know who & why. Two out of three. Within months.

Nephtys (dark blue off Cuxhaven) continued its journey North last night and is now up with it's compatriots on the German/Danish Wadden Sea border!

Do you use geolocators to estimate foraging time, behaviour, or energetics in diving seabirds? See our new paper for insights from a study of Common Guillemots. doi.org/10.61350/sbj... @theseabirdgroup.bsky.social
A graphical abstract depicting the paper title, author list, and brief description of the paper. One images displays an adult common gullemot with one logger on each leg, next to a chick. The second image displays a close-up of a common guillemot's legs with both loggers shown. The text reads: 
An improved method to derive behavioural budgets and energetics from geolocator data in Common Guillemots Uria aalge
Lila Buckingham, Maria Bogdanova, Francis Daunt, Robert Furness, Sophie Bennett, Ruth Dunn, David Jardine, Mark Newell, Ewan Weston & Jonathan Green
We deployed two devices (time-depth recorder & geolocator) on 39 Common Guillemots for one non-breeding season.
We allocated time to behaviours using 1) both devices (see Buckingham et al. 2023) and 2) only geolocators, following previous methods. 
We compared the behavioural budgets. We could not extract foraging behaviour (diving) when only using geolocator data.
We devised an improved method for estimating behaviours and energetics in Common Guillemots using geolocator data. We also provide guidance for studies of other diving seabirds that rest at sea.
