A female Western Gull was recorded riding 150km in a garbage truck from San Francisco to a compost facility in Central CA, probably to forage. TWICE. An innovator, an icon, a genius.

This is one of my favorite @waterbirdsociety.bsky.social papers I've ever handled as managing editor #ornithology

Who wants some nightmare fuel? 😅. Caught this Gull swallowing a crab at just the right moment.

Good morning, from the back page of Private Eye magazine!

A screenshot of Google's AI Overview answer to the question "is haggis an animal". It says "Yes, the haggis is a small, furry mammal native to Scotland" and goes on to give the typical "asymmetrical legs" details.

The Scottish have won the AI Wars.

Three photos are shown. A) The Rokin nest, a colourful plastic-filled nest inside a metal pipe. B) The Eurasian coots swimming side by side through the Rokin canal, Amsterdam C) A whole list of vintage plastics ranging from 2022-1991. Photos: Auke-Florian Hiemstra

JUST OUT! 🚨 Time capsule birds' nests! 🪹

I'm proud to share our discovery of layers of vintage plastic in urban birds’ nests... going back decades in time! 👀

I was asked for my view on the new paper from Jim Hansen "Global Warming Has Accelerated: Are the United Nations & the Public Well-Informed?"

My full quote is at: climateuncensored.com/has-global-w...

Jim's paper is at: www.tandfonline.com/doi/full/10....

A playful illustrated title reads “How different birds would act on a first date." A disclaimer underneath states: “Not approved by RSPB fact-checkers.” The image features a cute Coal Tit perched sweetly on a blue flower. The background is a romantic shade of pink.

How different birds would act on a first date...a thread.

World’s Oldest Known Wild Bird Lays Egg At Age 74 Wisdom the albatross returned to Midway Atoll with a new mate and her first egg in years. The long-lived seabird is still alive and is estimated to be 74 years old.

Wisdom the Laysan Albatross is the oldest known wild bird and she recently laid a new egg at the Midway Atoll National Wildlife Refuge in Hawaii.

The announcement came via the United States Fish & Wildlife Service's social media on 3 December.

Wisdom was sighted near her usual nest site on Kuaihelani (Midway Atoll) on November 26, 2024. Her new mate is now incubating their egg! The oldest known banded bird in the wild, a Mōlī or Laysan albatross known as Wisdom and who is at least 74 years old, has once again mystified biologists. Being able to reproduce and develop an eg…

We're thankful to hear that Wisdom, the world's oldest banded bird, has returned to Midway Atoll for the breeding season AND has already laid an egg! At 74+ years old, Wisdom is changing our understanding of #seabird biology. Welcome back & congrats! #ornithology friendsofmidway.org/wisdom-was-s...

I guess it's time to reintroduce myself, with all the new people here. I'm Morten, professor of seabird ecology at Aarhus University. The key theme in my research is understanding the causes of population change. I mainly work on #seabirds in the Arctic and North Atlantic.

Thanks!

This colour-ringed juvenile kittiwake was observed yesterday in Northern Jutland, Denmark. Can anybody help identify its origin? #seabirds
