A white band separates the breast from the red belly and vent. The upperside of the tail is deep blue and the underside is slaty gray. The folded wing has fine vermiculation that looks gray at a distance. The female's maxilla is slaty. Voice: The black-tailed trogon's song is "'kwo-kwo-kwo...' in series of up to 46 notes".

Masked Trogon
Trogon personatus
The masked trogon is a mid-sized trogon, averaging 27 cm (11 in) in length and 56 g (2.0 oz) in mass. Like all trogons, it displays sexual dimorphism. The upperparts, head, and upper chest of the male are variously glossy green, reddish-bronze, or golden-green (depending on the subspecies). The belly and lower breast are red; the latter separated from the greenish upper chest by a narrow white band. The male has a distinct eye-ring, which is red in most subspecies, but tending towards orange in the subspecies from the tepuis.
