Taxonomy and systematics

Three subspecies of slaty-tailed trogon are recognized as of 2021: the nominate ''T. m. massena'', ''T. m. hoffmanni'', and ''T. m. australis''. The last has sometimes been treated as a subspecies of black-tailed trogon (''T. melanurus'') or as a separate species.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A. Jaramillo, D.

Description

Trogons have distinctive male and female plumages, with soft, often colorful, feathers. The slaty-tailed trogon is long and weighs about . The nominate male has an orange-red bill and a dull black face, chin, and upper throat with a red to orange ring around the eye. The upperparts are metallic green that tends to golden green on the back and bluish green on the crown and rump. The breast is metallic green and the belly and vent deep red. The folded wing has fine black and white

that looks gray at a distance. The upperside of the four central tail feathers are metallic green to bronzy green with black tips, the next pair mostly black, and the outermost pair entirely black. The undersides of the tail feathers are slate gray with black tips. The female replaces most of the male's green with gray that is paler on the upper breast than on the upperparts. The upperside of the tail is black. The female's

Cornell Lab of Ornithology, Ithaca, NY, USA. https://doi.org/10.2173/bow.slttro1.01 retrieved October 27, 2021 The male ''T. m. hoffmanni''s plumage is essentially the same as the nominate's but the upperside of the tail is more golden. ''T. m. australis'' is smaller than the nominate. Compared to the nominate, the male's uppertail is bluish green and the female's darker gray. The male's undertail is browner than the nominate's and there is more metallic green on the face and throat.

Behavior

Feeding

The slaty-tailed trogon forages for fruits and insects by sallying or hover gleaning from a perch. It often follows white-faced capuchin monkeys (''Cebus capucinus'' and ''C. imitator'') to catch insects displaced by them.

Breeding

The slaty-tailed trogon's breeding season varies geographically, but appears to span from February to July overall. Males and females display to each other by raising the tail and fluffing the uppertail

nest or decaying tree trunk. Both sexes excavate the nesting chamber. The typical clutch is two or three white or bluish-white eggs, and both sexes incubate them.

Vocalization

The slaty-tailed trogon's song is "a steady deliberate series of ''cow'' or ''cue'' notes"; another description is "a deep full-throated ''wuk, wuk, wuk …''." Its calls include "a quiet clucking ''huh-huh-huh-huh''" and a "chuckling chatter".

has assessed the slaty-tailed trogon as being of Least Concern. It has a large range, and though its population has not been quantified it is believed to be stable. No immediate threats have been identified. However, "The primary threats to this species are logging of mature forests, and habitat conversion for agriculture."
