Taxon category: Accepted
Taxon origin
Taxon origin: Endemic
Habitat preferences: Tropical deciduous to wet forests.
Feeding type: Mainly insectivorous, has also been observed feeding on the flesh of fruits (Momordica, Scutia, Tournefortia) and on flowers, thus a potential pollen vector.
Reproductive biology: Territorial. Nests in cavities in trees or cactus. Lays 3-5 eggs. The species is known to nest in artificial cavities such as hollow electric poles or nest boxes.
Distribution origin: A recent genetic study has shown a single colonization event about 850 000 yrs ago from southern central America rather than continental Ecuador.
Distribution classification: Eutropical
Natural enemies: Affected by Philornis.
