Etymology: The guacharo is the oilbird, a nocturnal bird that roosts in caves across northern South America and navigates by echolocation, and "guacharoes" is simply its plural. The name itself comes from Spanish, where "guácharo" was an adjective meaning "sickly" or "dropsical," that is, afflicted with the swelling of dropsy. Spanish speakers likely applied it to the bird because of its pale, fleshy, somewhat sickly appearance, though the exact reasoning behind the naming is not recorded. The word sits in a small family of Spanish terms that also includes "guacharaca," the name of a different bird, a South American chachalaca. The two words share a similar sound and a connection to the region's birdlife, which is why they are usually grouped together in the etymological record.
