The magenta-throated woodstar (Philodice bryantae ) is a hummingbird that is a resident breeder in forest edge and scrub of the Talamancan montane forests.
The 9 cm (3.5 in) long, 3.5 g (0.12 oz) male magenta-throated woodstar is unmistakable with its magenta throat separated by a white collar from the green chest and flanks. The back is green and the belly is rufous. There are white rump patches, and the black-tipped tail is long and forked.
The female is 7.5 cm (3.0 in) long and lacks the male's long tail. Her plumage is generally like the male's but her throat is grey-buff instead of magenta, and the tail sides are rufous. Immature birds are like the female, but paler below and with buff fringes to the upperparts plumage.
The male gives a diving display flight alone or in loose groups. His song is a spluttering gurgle, and the call a dry chi or territorial chrrrrt.
These birds usually visit flowers of herbs, trees and scrubs for nectar, cocking their tails as they feed.
Its nest is undescribed.
