⚠️ BTO research predicts devastating declines in seabird populations in Britain & Ireland under future climate change. Some species face staggering losses by 2050, with up to 90% declines for Puffin and more than 70% declines for Arctic Tern and Fulmar. ➡️ bit.ly/seabirds-climate #Ornithology

We witnessed an exhilarating apex predator event yesterday as the 64s Orcas cruised through Bressay Sound here in Shetland. We've recorded them attacking birds many times in the last 25 years but the skill to hunt this drake Common Eider was incredible.

Yesterday the Puffin army returned, creeping closer and closer which allowed us to do a whole-island count. A staggering 13,174 were counted rafting, the highest number since 1934! Today, they made their first 2025 landfall, two days earlier than the 2013-2024 first birds ashore mean. Welcome home!

The Southern Shark Ecology Group has been tracking Tigers in the waters around Norfolk Island, with arrival and departure the same as Wedge-tailed Shearwaters. A huge 75% of their diet is seabirds! We are in the 1st stage of a collab to see if shark and shearwater migration areas match.#Seabirds🪶
Large shark held against a boat with tether ropes. Ocean around boat is calm. A person is leaning on side of vessel Grassy trail on a slope at night with several large birds alighted in the medium foreground and distance Large grey seabird being held with on leg extended. The leg has a bulky device affixed to the leg. The lighting shows it is nighttime.

Wilson's storm petrels, feeding in shallow waters (on amphipods, I think). Watch closely to see some fully submerging. This is the second time I've seen them diving. At Melchior Islands. #seabirds

From pilfering chips to swallowing whole starfish, gulls are known for their voracious appetites.

University of Salford ecologist @alice-risely.bsky.social wants people to upload their snaps of hungry gulls to the project's website: citsci.org/projects/gul...

Photographs of gulls eating anything from chips to starfish will help solve a scientific puzzle.

Subtropical breeding, surface-nesting Kermadec petrel chick on Phillip Island off Norfolk. Study in its 8th year. At one of our sub-colonies aptly named ‘Mars’. Feeling immensely privileged to have such access. #SuperSeabirdSunday 🪶

Great skua recovery at Hermaness and Noss national nature reserves is slow following the H5N1 influenza strain outbreak of 2022. Juan Brown of NatureScot shares more in an article for Sky News https://buff.ly/3BynKqX #seabirds
Seabird recovery 'painfully slow' after threatened species hit by killer bird flu
It could decades for the population of great skua at Shetland's national nature reserves to get back to pre-virus levels.
