Red-headed Trogon
Harpactes erythrocephalus
The red-headed trogon is on average 34 cm (13 in) in length. The male has a red head and breast, a unique feature in the Trogon group. The female resembles the Diard's trogon without a speckled undertail. The head, neck and upper breast of an adult male is dull crimson. A narrow white band crosses the mid breast, underneath which the lower breast to abdomen is light red to pink. Pale red can be observed on the flanks whereas the mantle and back of the bird are rusty brown. The male perches on branches with the support of mauve-blue legs. Voice: The male's call resembles that of the Eurasian golden oriole (Oriolus oriolus): a sequence of usually five to six, well-spaced mellow "tyaup" notes, repeated every minute. Occasionally the male calls an extended "pluu-du" note marked by a significant terminal drop in pitch. The call is repeated every 3–6 seconds.

Scarlet-rumped Trogon
Harpactes duvaucelii
The scarlet-rumped trogon is the world's smallest trogon, with adults measuring around 23–24 cm (9.1–9.4 in) with wings of 10 to 11 cm (3.9 to 4.3 in) in length, tails of about 11 to 13.5 cm (4.3 to 5.3 in), and weighing between 34 and 43 g (1.2 and 1.5 oz). Its eggs are estimated to measure 23.7 mm × 19.9 mm (0.93 in × 0.78 in) and weigh 5.2 g (0.18 oz). Males have a black head, neck and throat, but females and juveniles are a duller brown. Males have red underparts, rump and uppertail coverts along with rich buff or yellowish-brown upperparts and uppertail. Voice: Males have been recorded to emit a call of 12 short and rapid "yau" notes that accelerate in a diminuendo, sometimes to the point that they seem to merge, a much quicker call than other trogons. Females produce quiet rattles. When in alarm, the scarlet-rumped trogon utters quiet "kir-r-r-r" whirrings. This species also has a call that is similar to a scolding squirrel.
