caprimulgus

From capra (“goat”) + mulgeō (“I milk”). The sense "nightjar" is first attested in Pliny the Elder's Naturalis historia and represents a partial calque of Ancient Greek αἰγοθήλας (aigothḗlas), following Aristotle's claim in Historia animalium that certain nocturnal birds - often identified as nightjars - suck milk from the udders of goats.
