That’s what a group of researchers suggest in a paper recently published in Behavioral Ecology. Birds like cuckoos, who lay their eggs in songbirds’ nests, and whose young then off the hosts’ own chicks, tend to avoid cities. Songbirds may congregate in urban areas more than you’d expect.

According to Wikipedia, birds (class Aves) are feathered, winged, two-legged, warm-blooded, egg-laying vertebrates. Most researchers agree that modern-day birds are the only living members of the Dinosauria clade.

Like many birders, ever since I was a child, these wonderful, shy birds have been known as the Common Moorhen.
