The Goatsuckers fly in the dusk, in gloomy weather, or in 

 the shade of woods, or by moonlight, feeding on insects, 

 especially moths and beetles, which they seize on wing. 

 Their feet not being formed for grasping, they seldom perch 

 transversely on a branch. They nestle in a bare place on 

 the ground, laying two broadly elliptical eggs. Species occur 

 in most parts of the globe, but are not numerous in the colder 

 or temperate parts.

Upper parts grey, minutely dotted and undulated with 

 dusky, and variegated with yellowish-red, the head and back 

 longitudinally streaked with black ; lower parts transversely 

 undulated with light red and dusky. In the male, the outer 

 three quills have a large white spot on the inner web, and the 

 two lateral tail-feathers are largely tipped with white. The 

 young in their first plumage are similar to the female, but 

 somewhat darker. The claw of the middle toe has about ten 

 teeth, but frequently the tip is broken.
