The white-crested elaenia (Elaenia albiceps) is a species of bird in subfamily Elaeniinae of family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Chile, Colombia, Ecuador, and Peru. The white-crested elaenia was formally described in 1837 as Muscipeta albiceps by the French naturalists Alcide d'Orbigny and Frédéric de Lafresnaye. 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.

Rare
Under 5% of wildlife watchers report a White-crested Elaenia sighting in Buenos Aires on a given day, based on 137 verified sightings from GBIF citizen-science data. It is the 187th most-seen of the 274 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-crested Elaenia in Buenos Aires on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most White-crested Elaenia sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 10
Of the 10 cities where we can rate White-crested Elaenia sightings, Buenos Aires ranks 7th at under 5%. The best odds are in Santiago (Chile, about 30%), Quito (Ecuador, about 20%) and Mendoza (Argentina, about 10%).
GBIF citizen-science records
It is estimated from how often the White-crested Elaenia is recorded against all the birds logged in Buenos Aires (137 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
