The Royal Flycatchers are a genus, Onychorhynchus, of passerine birds in the family Tityridae. The genus contains four species: the Amazonian royal flycatcher, the Northern royal flycatcher, the Pacific royal flycatcher, and the Atlantic royal flycatcher. The common name for all the species in this genus, royal flycatcher, refer to the striking, colourful crest, which is seen displayed very rarely, except after mating, while preening, in courtship as well as being handled.
The Amazonian royal flycatcher (Onychorhynchus coronatus) is found in forest and woodland throughout most of the Amazon basin in northern Bolivia, eastern Peru, eastern Ecuador, eastern Colombia, Venezuela, the Guianas, and northern and western Brazil. They are 15–17.5 cm (5.9–6.9 in) in length and like to dart out from branches to catch flying insects or snap them up from leaves. They build very large nests (sometimes up to 2 m (6 ft 7 in) long) on branches near water. The nest hangs over the water which makes it hard for predators to reach. Credit: Wikipedia.
