Yesterday I learned that “chick-a-dee is a sort of battle cry that ralles other birds to mob a predator” and “The more dangerous a chickadee perceives a threat to be, the more dees it tacks onto the end of its call.” (Andy McGlashen, Audubon magazine, Fall 2026.) So our word for them is their word for us, and they’re not fans. #TIL #birds
