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. Read the summary at rbbp.org.uk/2023-report-... #ornithology #ukbirds 🧵[1/15]

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.
