Berwick Bank could kill more birds than any other windfarm on Earth, devastating colonies of Gannets, Puffins and Kittiwakes off Scotland’s coast. 🚨
We support renewables, but not at catastrophic cost to seabirds already in crisis.

⚠️ 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🪶

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

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.

Marine heat wave confirmed cause of death for 4 million birds (Common Murres) in 2016. Half of Alaska’s Common Murre population at the time. Largest documented animal die-off in modern history.
As little as 2C temp increase drastically their altered food chain.
