White-crested Elaenia

The white-crested elaenia (Elaenia albiceps) is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers.

They noted that the species occurred in Rio de Janeiro in Brazil, the Yungas region in Bolivia and the Tacna region of Peru. In 1925 the Austrian ornithologist Carl Eduard Hellmayr restricted the type locality to the Yungas region in Bolivia based on the provenance of the type species. The specific epithet albiceps combines the Latin albus meaning "white" with -ceps meaning "-headed". The white-crested elaenia is now placed in the genus Elaenia that was introduced in 1836 by the Swedish zoologist Carl Jakob Sundevall.
