Distinguishing Characteristics

The Blue Ground-Dove is a small, sexually dimorphic dove. The male is pearly blue-gray overall, with black spots on the secondaries and wing coverts, and entirely black primaries. The female is cinnamon-brown, with a rufous rump, dark brown spots on the secondaries and wing coverts, and blackish primaries. The association of the bluish male and rufescent female is often the first clue to identification.

Similar Species

The male Blue Ground-Dove is almost unmistakable. The female Blue Ground-Dove is similar to female Maroon-chested Ground-Dove (Claravis mondetoura), but Maroon-chested has a buffy face, is browner on the underparts, has broader, purplish (not chestnut) bars on the wing coverts, and has white tips to the outer rectrices; Maroon-chested Ground-Dove also usually occurs at higher elevations.  The female Purple-winged Ground-Dove (Claravis godefrida) also has broader, purplish wing bars and the rump and tail are less rufescent.

Female Blue Ground-Dove is larger than Columbina ground-doves, is longer tailed, and lacks black spots on wings and the back.
