Colombe rousse

Leptotila megalura

Une colombe trapue de taille moyenne des vallées sèches interandines, des yungas et des forêts de Tucumán, avec un mélange de Podocarpus et d'aulnes. Souvent seule ou en couples. L'anneau orbital varie du bleu-violet au nord de la courbure des Andes au rouge au sud de cette courbure. Son aire de répartition chevauche celle de la très similaire Colombe à queue blanche, et elle est mieux séparée par la voix, et, chez certaines populations, par la couleur de la peau orbitale (bleue chez la Colombe à queue blanche). L'iris est également généralement plus sombre que celui de la Colombe à queue blanche. Elle est le plus souvent trouvée et facilement identifiée par son chant grave et bégayant.

Identification

The Yungas dove is 29 to 32 cm (11 to 13 in) long. The adult's forehead is grayish and its crown bluish gray. The eye is very dark and is surrounded by white feathers; the rest of the face is buff or pinkish buff. Its upperparts and tail are a dark ruddy brown with a purple gloss on the hindneck and upper mantle. Its breast and the sides of the neck are grayish pink lightening to white on the belly. The adult sexes are similar; the juvenile is duller and its wing coverts appear scaly.

Taxonomie

The Yungas dove is monotypic. However, the southern population has sometimes been suggested as a distinct subspecies. The Yungas dove and the grey-fronted dove (L. rufaxilla) are sister species.
