City birds aren't just living in trees and in the nooks of tall buildings... they're also making themselves at home in our traffic lights! The NY Post has a cute story about a family of sparrows that lives inside of a crosswalk signal on the Upper West Side. And the only way they'll leave is if the Department of Transportation physically removes them (which they have threatened to do once they find the signal—location undisclosed!). Urban bird specialist Karen Purcell told the paper, "They are fierce nest competitors. They are able to evict other birds, even native species. They are survivors." Can someone please write a children's book about this little feathered family?
