The Amethyst-throated Mountain-gem or amethyst-throated hummingbird (Lampornis amethystinus) is a species of hummingbird in the family Trochilidae. It is found in El Salvador, Guatemala, Honduras, and Mexico.[2] Its natural habitat is subtropical or tropical moist montane forest. One confirmed sighting of a male Amethyst-throated hummingbird had occurred in West Texas by Cornell Lab of Ornithology on one of their online live webcams on October 15, 2016.

Description[]

The species exhibits sexual dimorphism where the males have a range of pink to blue throats and the females have a more tan colored throat.[2] Juveniles of both sexes look similar to females but often with a few pink feathers on the throat.[2]

When compared to similar sister species, it appears the color differences between this and others was a relatively recent evolutionary occurrence.[3]

Behavior[]

Generally the species focuses more on nectar than insects through traplining in under and midstory of forests.[2]

It is predominately unterritorial.[2] Its mating call occurs during mornings and evenings. If a female is attracted, the male will perform an aerial display. It starts by flying parallel to the ground in circles, dives towards the female, returns to its perch, and repeats this a handful of times.[2][4]

The nests are built by the females a couple meters off the ground with a clutch size of two white eggs.[2]
