It has an extensive range south of the African equator. Despite not having a completely "square tail", its naming highlights a distinguishing field mark. The similarly plumaged slender-tailed nightjar, found in dry bush country of the tropics, differs namely by its protruding central tail feathers. It is alternatively known as the Gabon nightjar or Mozambique nightjar. RangeIt occurs mainly south of the equator in Africa, but enters the tropics during the northern hemisphere summer. An isolated race occurs in Equatorial Guinea and western Gabon. It is a seasonal visitor to the northern DRC, northern Tanzania, southern Kenya and southern Uganda. It occurs year-round in Angola, Botswana, Burundi, Republic of the Congo, Lesotho, Malawi, Mozambique, Namibia, Rwanda, South Africa, Swaziland, Tanzania, Zambia and Zimbabwe.[2] CallThis bird's call is a prolonged churring, which alternates between a fast and slow pace roughly every second. As such it differs from the similar long-tailed and slender-tailed nightjars which produce fast and slow churrs respectively.[2] Subspecies
