Rock Pigeon

The Rock Pigeon a.k.a the rock dove is a relatively medium-sized birds. Rock pigeons usually have  different colors and pattern but the majority of birds are bluish gray with black bands on the wing and iridescent throat feathers. Also they are not sexually dimorphic. Rock Pigeons often operate in flocks, so help each other point out food and alarm others when there is danger. Because these birds are foragers you will usually see a flock of rock pigeons eating seeds, grain, and anything they find on the ground. Also they live all over North America and Southern Canada year-round, so you can actually see in most places, especially urban areas. Something special about these birds is that they can find their way home, even if released from a distant location blindfolded. They do this by sensing the earth’s magnetic fields, and perhaps also by using sound and smell. They can also use cues based on the position of the sun.
