Who the heck gave it the totally inapt name "standard winged"?

Standard winged night jar - 25 seconds

Surely one of the most spectacular of all night jars, the adult male has a bizarre and unusual wing ornament during the breeding season which consists of a broad central flight feather on each wing elongated to 38 centimetres (15 in), much longer than the bird's body. 20 centimetres (7.9 in) or more of this is bare shaft. In normal flight, these feathers trail behind, but in display flight they are raised vertically like standards.

Outside the breeding season, there are no plumage distinctions between the male and female.
