The Amazonian royal flycatcher (Onychorhynchus coronatus) is a passerine bird of the tyrant flycatcher family. It 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. Amazonian royal flycatchers 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.
