Eupherusa eximia

Stripe-tailed Hummingbird

This species is named for the white edges to its otherwise black outer tail feathers. It is a medium-sized hummingbird with a fine, slightly downcurved bill, and has a predominantly green plumage with a reddish wing patch and, in the female, gray-white underparts. Aside from the nominate, there are two subspecies, the more olive-green subsp. nelsoni and the whiter-tailed subsp. egregia. Males of the species are notably territorial and aggressive, usually defending clusters of epiphyte flowers in the canopy. Females are more likely to trapline and to visit lower strata in the forest. The nest is built quite low down in thick cover and is sometimes decorated with bright red lichens. Post-breeding, there is marked dispersal to lower altitudes, particularly in Costa Rica and Panama. The population trend is not known, but subsp. nelsoni, the most northerly subspecies, is likely to be under particular pressure from deforestation.
