Glossy Flowerpiercer

A medium-sized flowerpiercer with glossy, iridescent blue-black plumage that catches light with a deep metallic sheen, glossy flowerpiercers use their specialized hooked bill to pierce flower bases and rob nectar without effecting pollination — a form of nectar theft that has evolved independently multiple times in birds. Found in humid Andean cloud forest and forest edges from Colombia to Bolivia at elevations of 1,500–3,500 meters. Common in forest edges and gardens with abundant tubular-flowered plants.
