Diard's Trogon
Harpactes diardii
The Diard's trogon is a medium-sized bird, measuring approximately 34 cm (13.4 in) in length and weighting about 100 g. Like other trogons, it has hunched shoulders, a long tail and vibrant plumage with a striking mix of contrasting colors. Males and females are similar in size but showcase differences in their plumage. Both males and females have a blue bill with a black tip. The adult male has a black head and upper breast paired with a purplish-blue eye ring. Its mid-crown to hind-crown has a maroon wash, while the hind collar and breastline are pink. Voice: The Diard's trogon vocalizations are characterized by a sequence of 10 to 12 "kau" notes, with the second note higher than the first, while the subsequent notes generally decrease in pitch. The final few notes usually descend further, resulting in a characteristic and rhythmic sequence.

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.
