Bird collisions with human-made structures - also known as
#anthropogenic collisions - are a global conservation crisis. While we primarily associate such collisions with little songbirds, raptors bear the brunt of this menace more than we might think.
A 2024 report in the Journal of Raptor Research, titled Conservation Letter: Raptor Collisions in Built Environments, highlights the scale of the issue:
🦅Window collisions affect 45% of urban raptor species in the US and Canada.
🦅Raptors like Sharp-shinned Hawks, Merlins, Cooper’s Hawks, and Peregrine Falcons have suffered severe population declines.
🦅High-speed hunters like Cooper’s Hawks and Sharp-shinned Hawks are especially at risk because they collide while chasing prey near windows.
🦅Younger birds are especially affected, which can have long-term impacts on populations.
