oilbird
Cave-dwelling night flyer
The oilbird is a nocturnal South American cave-dwelling bird that feeds on fruit, especially palm nuts.
Named for the oil extracted from its fat chicks, which was once burned in lamps.
Oilbirds navigate dark caves using echolocation, one of few bird species to do so: The oilbirds emerged from the cave at dusk to forage.
