Over millennia of following us into new habitats, crows also learned that we are a fickle species. Humans provide food, but sometimes we harass or kill them. Our settlements can be alternately deadly or sheltering. To “avoid danger and take advantage of riches,” Marzluff says, “they can’t not be interested in people.” So they’ve evolved to watch closely what humans do. And their keen attention may be key to a friendship that’s singular.
