White-tipped Sicklebill

A large hermit hummingbird of humid forests in Central America and northwestern South America, white-tipped sicklebills possess dramatically curved, sickle-shaped bills precisely adapted to extract nectar from the strongly curved flowers of Heliconia plants — a textbook example of plant-pollinator coevolution. They travel systematic trap-line routes through dense humid forest, visiting the same flower patches daily. Both sexes share the sickle-bill, and they sing persistent, repetitive songs from forest undergrowth.
