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.
