The latest report from the RBBP, Rare Breeding Birds in the UK in 2023, is out now in British Birds. It reports on the 104 species and races of rare breeding birds recording breeding, or showing signs of breeding, in 2023.

I've been pretty quiet here lately, trying to cut down on doomscrolling for the sake of my mental health... BUT I have a new story out at @therevelator.org, on how climate change is contributing to bird population declines in multiple biomes around the world. #birds 🪶🌏

Studies: Extreme Weather Fueled by Climate Change Is Adding to Bird Declines • The Revelator

Scientists have typically pointed to habitat loss as the key factor behind the worldwide drop in bird populations worldwide, but climate change poses a second, closely linked threat.

Our team analysed the correlation of N deposition with numbers of territories of 112 Swiss breeding birds species. Insectivous and herbivorous species were more negatively associated with N deposistion, as well as ground-nesting species. Read more here: doi.org/10.1111/cobi...

Say we get a far right government

that undermines & misuses science?

Do academics continue to argue that they just do the science, & it’s not for them to advocate

even while their research is thrown on the scrapheap?

NEW PAPER: Artificial nest boxes trap more heat than natural burrows, pushing little penguins beyond safe thermal limits. As temperatures increase, nest box design improvements are critical to prevent population declines.
