Crows Are the New Pigeons
Every night as dusk falls in Portland, Oregon, the sky fills with birds. While workers make their way from the city center toward their homes, crows leave the suburban lawns where they’ve spent the day picking for grubs to fly downtown. They swirl across the river in large groups, cawing as they go. A community science project recently recorded 22,370 crows spread out downtown—about twice as many as the number of people who lay their heads in that neighborhood.
