Habitat Comparison
Belted Kingfisher
Rivers, streams, lakes, ponds, estuaries, and coastlines with clear water and suitable perches. Nests in burrows dug into earthen banks.
Rock Pigeon
Originally cliff-nesting in Mediterranean regions. Now the quintessential urban bird, inhabiting cities worldwide on every continent.

About These Birds

Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
