White-tailed starfrontlet

The white-tailed starfrontlet (Coeligena phalerata) is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae. It is endemic to the Sierra Nevada de Santa Marta of northeastern Colombia.

The white-tailed starfrontlet is about 14 cm (5.5 in) long. Both sexes have a long, straight, black bill, with the female's being somewhat longer than the male's. Both sexes have a white spot behind the eye. Both sexes also have a forked tail, but the male's is more deeply indented than the female's. Adult males have metallic dark green upperparts with a glittering turquoise crown. The entire tail is white, though the feathers when fresh have bronze tips. They have a blue gorget, mostly emerald green underparts, white leg puffs, and white undertail coverts. Adult females have a dusky blue-green crown and shining green upperparts. The tail is bronzy with pale buff tips to the feathers. Its underparts are rufous cinnamon. Immatures are similar to the adult female.
