The oilbird (Steatornis caripensis), locally known as the guácharo, is a bird species found in the northern areas of South America including the Caribbean island of Trinidad. It is the only living species in the genus Steatornis, the family Steatornithidae, and the order Steatornithiformes. Nesting in colonies in caves, oilbirds are nocturnal feeders on the fruits of the oil palm and tropical laurels. They are the only nocturnal flying fruit-eating birds in the world (the kākāpō, also nocturnal, is flightless). They forage at night, with specially adapted eyesight. However, they navigate by echolocation in the same way as bats, one of the few birds to do so. They produce a high-pitched clicking sound of around 2 kHz that is audible to humans.
Oilbirds are related to the nightjars, both being in Strisores, and were previously placed alongside nightjars in the order Caprimulgiformes. However, the nightjars and their relatives are insectivores while the oilbird is a specialist frugivore, and it is now deemed sufficiently distinctive to be placed in its own order Steatornithiformes, suborder Steatornithes, and family Steatornithidae.

No species of the same family or order lives in Corcovado National Park, so these are its closest relatives here: other birds.
Rare
Under 5% of wildlife watchers report an Oilbird sighting in Corcovado National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 284th most-seen of the 332 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report an Oilbird in Corcovado National Park on a given day, against under 5% in October to August, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Oilbird sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Oilbird sightings, Corcovado National Park has the highest daily chance: under 5%. Next come Parque Natural Metropolitano (Panama, under 5%) and Monteverde Cloud Forest Reserve (Costa Rica, under 5%).
GBIF citizen-science records
It is estimated from how often the Oilbird is recorded against all the birds logged in Corcovado National Park (27 verified sightings from 2019 to 2026), 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.
