Size Comparison
Habitat Comparison
Barn Swallow
Open farmland, meadows, and areas near water. Nests almost exclusively in human-made structures such as barns, bridges, and eaves.
Rock Pigeon
Originally cliff-nesting in Mediterranean regions. Now the quintessential urban bird, inhabiting cities worldwide on every continent.
Song & Call Comparison
Barn Swallow
A rapid, twittering song: a long stream of 'vit-vit-vit' and rolling chirps. Also gives a sharp 'vit' flight call. Song can last many minutes without pause. Musical and liquid.
Rock Pigeon
Soft, rhythmic cooing 'roo-c'too-coo' repeated multiple times, with emphasis on second syllable. Male courtship coo is deeper and more persistent. Wing-clapping on takeoff is loud.
Geographic Range & Migration
Barn Swallow
Breeds across the Northern Hemisphere in North America, Europe, and Asia. Winters in South America, Africa, and South Asia.
Rock Pigeon
Native to Europe, North Africa, and South Asia. Feral populations on every continent except Antarctica.

About These Birds
Barn Swallow
The barn swallow is the most widespread swallow species in the world and has one of the longest migrations of any passerine. Its arrival signals spring across the Northern Hemisphere, inspiring cultural references from ancient Greece to modern poetry. Barn swallows have become almost entirely dependent on human structures for nesting.
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.
