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.

White-sided Flowerpiercer

A medium-sized flowerpiercer of humid Andean cloud forest and forest edges from Colombia south to Bolivia, white-sided flowerpiercers have distinctive white flank patches contrasting with dark grey-blue plumage. Like all flowerpiercers, they use their sharply hooked and slightly upturned bill to pierce the base of tubular flowers and steal nectar without pollinating — earning them the reputation as nectar thieves. Found at elevations of 1,500–3,500 meters, they are commonly encountered in Andean gardens and forest edges.
