Eurasian Collared Dove

Size & Shape
Eurasian Collared-Doves have plump bodies, small heads, and long tails. They’re larger than Mourning Doves but slimmer and longer-tailed than a Rock Pigeon. The wings are broad and slightly rounded. The broad tail is squared off at the tip, rather than pointed like a Mourning Dove’s.

Color Pattern
Eurasian Collared-Doves are chalky light brown to gray-buff birds with broad white patches in the tail. The bird’s collar is a narrow black crescent around the nape of the neck. In flight and when perched, the wingtips are darker than the rest of the wing.
