The Rock Pigeon, or Rock Dove, is a common bird in North America.The adult is 11
to 15 in long with a 24 to 28 in wingspan.
Weight for wild Rock Doves ranges from 238 to 380 grams , though overfed domestic and semi-domestic individuals can
exceed normal weight.
The rock pigeon has a dark bluish-gray head, neck, and chest with glossy yellowish,
greenish, and reddish-purple iridescence along its neck and wing
feathers. The iris is orange, red or golden with a paler inner ring, and
the bare skin round the eye is bluish-grey. The bill is grey-black with
a conspicuous off-white cere, and the feet are purplish-red.
Rock pigeons are the same kind of pigeon that was used in wars to send letters, that's why they are sometimes called messaging pigeons or carrier pigeons.
