Mourning Doves

Wikipedia reports:

The Mourning Dove (Zenaida macroura) is a member of the dove family (Columbidae). The bird is also called the Turtle Dove or the American Mourning Dove or Rain Dove, and formerly was known as the Carolina Pigeon or Carolina Turtledove. It is one of the most abundant and widespread of all North American birds. Its plaintive woo-OO-oo-oo-oo call gives the bird its name. The wings can make an unusual whistling sound upon take-off and landing. The bird is a strong flier, capable of speeds up to 55 mph.

Mourning Doves are light grey and brown and generally muted in color. Males and females are similar in appearance. The species is generally monogamous, with two squabs (young) per brood. Both parents incubate and care for the young. Mourning Doves eat almost exclusively seeds, but the young are fed crop milk by their parents.
