The '''sharpbill''' ('''''Oxyruncus cristatus''''') is a small [[passerine]] bird that is placed in its own family '''Oxyruncidae'''. It was formerly placed in the family [[Tityridae]]. Its range is from the mountainous areas of tropical [[South America]] and southern [[Central America]] ([[Panama]] and [[Costa Rica]]). 

It inhabits the canopy of wet forest and feeds on [[fruit]] and some [[invertebrate]]s. It has an orange erectile crest, black-spotted yellowish underparts and scaling on the head and neck. As its name implies, it has a straight, pointed beak, which gives its common name.

Sharpbills are most commonly found in tall dense forests but occasionally venture to the forest edge. Their diet consists of primarily of fruit, but they will also take insects, hanging upside down in from twigs to obtain insect [[larva]]e. They will also travel in [[mixed-species feeding flock]]s with [[ovenbird (family)|ovenbirds]], [[tanager]]s, [[woodpecker]]s and [[cotinga]]s. The breeding system employed by this species is [[Animal sexual behaviour#Polygamy|polygamous]] with closely grouped males displaying in from a [[Lek mating|lek]].<ref name="Stiles">{{cite journal|last1=Stiles|first1=F.

Chicks are fed by regurgitation.
