Fawn-breasted Brilliant
Heliodoxa rubinoides
The fawn-breasted brilliant is a medium-sized hummingbird, measuring 11 to 13 cm (4.3 to 5.1 in) in length and weighing approximately 7.2 to 10.2 g (0.25 to 0.36 oz). The bill is stout, fairly long (22–27 mm (0.87–1.06 in)), slightly decurved, and black. Adult males have shining bronzy-green upperparts, with coppery tones on the wing coverts and a slightly forked, coppery-green tail. The underparts are warm buffy-cinnamon, with irregular green spotting on the flanks and throat sides. A distinctive feature is the small, isolated pinkish to lilac gorget patch on the lower throat. Voice: The fawn-breasted brilliant produces two main vocalizations: a series of sharp, metallic "tchik" notes, often given in rapid succession as an alarm or territorial warning, and a common "swi-swi-swi-swu" call. Non-vocal communication includes the audible buzzing of wings during flight and displays, as well as tail fanning during aggressive or courtship interactions.

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".
