Green-tailed Trainbearer

A medium-sized Andean hummingbird with a long, deeply forked green tail — the longest tail relative to body size among trainbearer hummingbirds — male green-tailed trainbearers inhabit open grassland, scrub, and Andean hedgerows from Ecuador to Bolivia at elevations of 2,000–4,000 meters. Males perform aerial display flights with the ornamental tail streaming behind. Found in semi-open Andean landscapes including gardens, agricultural areas, and páramo edges where they feed at diverse flowering plants.
