Schwarzbauchtrappe Lissotis melanogaster

A lithe, medium-sized bustard with black daubs on a mostly tan-colored back. The male has a black belly, neck stripe, throat, and face patch. The female is uniform buff-brown from the belly to the head. In flight, both sexes have white windows in the wings. Singles and pairs inhabit tall grassland and grassy savanna. Its strange display involves the male stretching his neck and making a frog-like “kwoork” croak, and as he retracts his head to the shoulders, follows with a “grrrr” growl and champagne-cork-like “pop” while his head lifts again. He also performs an aerial display with the wings held back rigidly and with a puffed throat exposed.
