Andean Emerald
Uranomitra franciae
The Andean emerald is 9 to 11 cm (3.5 to 4.3 in) long. Males weigh about 5.6 g (0.20 oz) and females about 5.3 g (0.19 oz). Both sexes of all subspecies have a straight to slightly decurved bill of medium length with a blackish maxilla and a coral red mandible with a dark tip. Adult males of the nominate subspecies U. f. franciae have a glittering violet-blue crown and glittering golden- to emerald green cheeks and neck. Their upperparts and flanks are light green to golden-green with a coppery tinge to the uppertail coverts. The center of their underparts is white. Voice: The Andean emerald has a quite variable song, typically described as "a repeated complex phrase of high-pitched squeaky whistles, trills and scratchy notes." It also makes "a high-pitched 'tsip'" call, and during social interactions "scratchy squeaky chatters".

Green-crowned Brilliant
Heliodoxa jacula
Male green-crowned brilliants are 12 to 13 cm (4.7 to 5.1 in) long and females 10.5 to 12 g (0.37 to 0.42 oz). One female weighed 7.4 g (0.26 oz). Both sexes of all subspecies have a white spot behind the eye and a forked tail, though that of the female is not as deeply indented as the male's. Adult males of the nominate subspecies have a glittering green to blue-green head and breast with a small metallic violet-blue patch on the throat. The upperparts and belly are bronzy green, the vent area white, and the thighs also white. The tail is blue-black. Voice: The green-crowned brilliant makes "a loud and squeaky kyew or tyew call". In Costa Rica, displaying males make "a tseek, tseek, tseek" call. During chases the species makes "loud sputtering notes and squeaks".
