In the Americas, the black collar on its hindneck is shared by the Eurasian Collared-Dove (also introduced), but note that Eurasian Collared-Doves are generally darker overall, have more extensive black at the base of the undertail, and the primaries are distinctly darker than the remainder of the wing. In flight, Eurasian Collared-Doves have a tricolored pattern to the upperwing rather than the somewhat uniform appearance of African Collared-Doves. Song is “oo-rrroooo-oooo,” loudest at start, than trailing off.
