Prachtkehlelfe

A tiny, high-altitude Andean woodstar hummingbird, male gorgeted woodstars have a spectacular iridescent pink-purple gorget that is disproportionately large relative to their 2.5 g body. Found in montane forest edges and gardens from Colombia and Venezuela to northwestern Peru at elevations of 1,500–3,500 meters. Like all woodstars, they perform buzzy, insect-like hovering flight in open areas near flowers. They enter deep nocturnal torpor — a near-death metabolic state — to survive cold Andean nights.
