The Black-tailed Trogon is distributed in the Amazon Basin with 2 disjunct populations in Panama, northern Colombia and north-west Venezuela. See the distribution map at Birdlife International.

It is found in the canopy and sub-canopy of forest and forest edges where it feeds on fruits including Cecropia as well as insects. It often accompanies mixed-species canopy flocks.

The male, shown here in photos 1, 2 and 3, has a yellow bill, an orange-red eye-ring and a thin white band across the chest separating the dark green breast from the red belly.

The female, seen in photos 4 and 5, is grey above and below with the exception of the red lower belly. Note also the grey on the upper mandible which is a feature of the nominate subspecies but not some of the other subspecies. The female has virtually no eye-ring.

There are illustrations in HBW, Volume 6, Page 121; and Hilty & Brown, Plate 17.
