The flag nightjar ( Caprimulgus vexillarius ), also known as the rudder wing , is a species of bird from the nightjar family (Caprimulgidae).
For a long time it was placed in its own genus Macrodipteryx together with the flag nightjar ( Caprimulgus longipennis ) , but after molecular genetic comparisons it was counted back to the genus goat milkers ( Caprimulgus ) from 2010 .
It occurs in Angola , Botswana , Democratic Republic of the Congo , Namibia ( Caprivi Strip ), South Africa and Tanzania . It is an intra-African migratory bird and winters between Nigeria , Uganda and Kenya .
Their distribution area mainly includes miombo or mopane , also cleared or burned forest areas, bushland or bushy grassland between 1000 and 2800 m.

The flag nightjar is 24–28 cm tall (excluding the male's "flag feathers", which are 48 to 78 cm long), the male weighs between 59 and 79, the female between 65 and 88 g. Brooding males are distinctive with wide white stripes across the wings and long white elongated feathers on the second hand wings . The female has a red-brown neck band and strong black and red-brown wing bands, no white. It is similar to the female flag nightjar, but is larger.

Hazardous situation
The flag nightjar is not considered to be endangered ( least concern ).
