About Coeligena phalerata (Bangs, 1898)
The white-tailed starfrontlet (scientific name Coeligena phalerata (Bangs, 1898)) is approximately 14 cm (5.5 in) long. Both males and females have a long, straight black bill, and the female's bill is somewhat longer than the male's. Both sexes also have a white spot behind the eye and a forked tail, though the male's tail has a deeper fork than the female's. Adult males have metallic dark green upperparts and a glittering turquoise crown. Their entire tail is white, though newly grown tail feathers have bronze tips. Adult males 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. Their tail is bronzy, with pale buff feather tips, and their underparts are rufous cinnamon. Immature white-tailed starfrontlets resemble adult females. The white-tailed starfrontlet is found only in the isolated Sierra Nevada de Santa Marta in northeast Colombia. It inhabits humid to wet montane forest; males prefer openings within the forest, while females are more often encountered at the forest edge. Its elevational range is between 1,400 and 3,700 m (4,590 and 12,140 ft).
