⚠️ 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. ➡️

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.

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.

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. 🧪🌎🦉

Fluff ball update! Our last two Storm-petrel chicks in the nest boxes on Nólsoy (Faroe Islands) are SO CLOSE to fledging now. Here's some pics from Jens-kjeld on 28th November. Will they fledge this week?? Fledglings have been seen on Christmas Day before in the Faroes!

Mass bleaching of corals on the Great Barrier Reef in early 2024 was the most severe and most widespread yet recorded - surpassing 1998, 2002, 2016, 2017, 2020 & 2022. The overall mortality rate this year will exceed the 30% loss in 2016.
