Distinguishing Characteristics

The Ruddy Quail-Dove is a medium-sized (23.0-25.5 cm) columbid, with a typical quail-dove (Geotrygon) stocky build. Sexes differ in plumage. The upperparts of the male are primarily brownish rufous; the most distinctive feature is a brownish rufous stripe across the sides to the head, which are buff. The underparts are primarily buffy. The female is similar in pattern, but duller, with plive-brown upperparts.

Similar Species

Ruddy Quail-Doves are similar in size and shape to other species of quail-dove (Geotrygon), but the combination of overall brown or rufous-brown coloration and the dark stripe across the paler cheek is distinctive. The Ruddy Quail-Dove also can be confused with species of Leptotila, which also forage on the ground under vegetative cover; but all species of Leptotila have longer tails, which in most species also have prominent white tips to the outer rectrices; many species of Leptotila also have gray breasts and/or forecrowns, and no species of Leptotila has a stripe across the sides of the head.

Detailed Description

The following description of nominate montana is based on Wetmore (1968); see also Ridgway (1916):

Adult male: Upperparts rufous-chestnut, paler on the forehead and wings; nape and back glossed with reddish purple. Throat and sides of the head pinkish cinnamon; sides of the head, below the auriculars, crossed by a reddish purple stripe. Breast vinaceous-fawn, turning to buff on belly. Sides and flanks cinnamon-buff to clay. Undertail coverts cinnamon-buff. Underside of wing cinnamon-rufous.

Adult female: Forecrown and sides of head dull cinnamon; sides of the head, below the auriculars, crossed by an olive stripe. Most of upperparts otherwise olive; primaries and greater wing coverts dusky, edged with cinnamon. Rectrices olive, except for blacker outer rectrices. Throat buffy white. Breast dull cinnamon to wood brown, changing to buff on belly; undertail coverts more cinnamon. Sides and flanks olive-brown. Underside of wing dull cinnamon-buff to dull rufous

Juvenile: Upperparts dark olive to dusky, forecrown paler. Tertials, wing coverts, remiges and rectrices tipped and edged with cinnamon. Breast olive-brown tipped with cinnamon, rest of underparts buffy white to buff. Males in this plumage are lighter and more brightly colored than females.
