Hello, Sechelt. There are two rooftop GW Gull nests in this picture. Can you guess where? Answer below.

In the UK, 2021-2023, 103,497 carcasses of 155 species tested for HPAI. Gannets, Black-headed Gulls, Barnacle Goose most affected. 7500 +ve for HPAI across 80 species. Mortality data to estimate impact.

Across 13 European countries, only 3 dead Little Terns found in 2022-2023, amongst tens of thousands of breeding birds. Surprising given how other tern species have been impacted.

the ivory gull, one of the most fascinating birds of the Far North!
It stays in the Arctic all winter and follows polar bears to feed on the leftovers of their kills — a brilliant and icy survival strategy ❄️🐻‍❄️

Sketches of the Mediterranean gull... I quite like the one sunbathing 😎
These humorous drawings are based on real biology!

Sketches of mediterranean gull characters. They are enjoying the sun with sunglasses and cocktail. The idea is to illustrate its wintering grounds—far from the cold of Northern Europe ❄️. So the bird is shown in its non-breeding plumage (yes, the black head is just for summer!) Sketches of mediterranean gull characters. One is flying, an other one on the water and an other one is taking off its sunglasses. Sketches of mediterranean gull characters. One has a breeding plumage and try to seduce a partner and the other one is looking at it's tags on its legs...

A nice article on urban gulls' eating habits that doesn't paint them in a negative light. With some commentary from me, @alice-risely.bsky.social and others.

This seagull took an 80-mile truck ride twice to find food
Researchers say it's the first recorded case of a seagull using a vehicle for transport while foraging.

I endorse this post 100%. "Automatic inference" is mostly an abomination. I have zero tolerance for it in ecology.

Finally the first Kittiwake egg! Three days later than last year and ten days later than average. Only five later dates. Due to birds being in poor condition or the dry conditions making nest building difficult? Maybe time will tell

Why is Antarctica so important?

Antarctica might feel very remote - until you look at the planet from a different perspective. It's actually central to our world's ocean currents.

🎁 Check the alt text to dig into this diagram

🌊 This is from a new book by BAS' @oceanandice.bsky.social (et al.)
The image shows a map of the world's currents, but looking at a projection of the world from the bottom of the globe, with Antarctica at its centre. The diagram shows all of the world's currents cycling through major oceans, all linked together by a central circular current that goes around the outside of the Antarctic continent. "The Southern Ocean around Antarctica is central to global ocean circulation. It enables connectivity across the whole planet by linking the Atlantic, Pacific and Indian Ocean basins, and is the key site where waters are returned to the surface from depth and then converted into new water masses. The clockwise circulation of waters around Antarctica is the Antarctic Circumpolar Current, the strongest ocean current system in the world." (Figure 1.1 from "Antarctica and the Earth System", edited By Michael P. Meredith, Jess Melbourne-Thomas, Alberto C. Naveira Garabato, Marilyn Raphael)
