Lyre-tailed Nightjar

The male lyre-tailed nightjar has extremely long outer tail feathers from which the species gets its name; they are more than twice as long as its body. The female's tail is much shorter and less graduated. Adults of the nominate subspecies are 23.5 to 28 cm (9.3 to 11 in) long excluding the tail streamers. The tail exceeds 60 cm (24 in) in length. Males weigh about 70 g (2.5 oz) and females about 77 g (2.7 oz). The male's upperparts are brown. Its crown and nape are spotted with grayish white, buff, tawny, and cinnamon; the back also has tawny and cinnamon spots. Voice: The lyre-tailed nightjar's song is a "rollicking...5-11 rising wéeou-tee notes". It is mostly sung at dusk, from a perch or the ground. It is also given in flight or when chasing a female. The male's display flight includes a rapid series of "weep-weep-weep-weepupup" sounds.
