Rufous-naped Lark

The rufous-naped lark or rufous-naped bush lark is a widespread and conspicuous species of lark in the lightly wooded grasslands, open savannas and farmlands of the Afrotropics. Males attract attention to themselves by a bold and often repeated wing-fluttering display from a prominent perch, which is accompanied by a melodious and far-carrying whistled phrase. This rudimentary display has been proposed as the precursor to the wing-clapping displays of other bush lark species. They have consistently rufous outer wings and a short erectile crest, but the remaining plumage hues and markings are individually and geographically variable. It has a straight lower, and longish, curved upper mandible.
