Male Tawny Frogmouths are generally larger than the females.
Breeding season for these birds occurs during August-December, to where a clutch size of 2 - 3 eggs will be laid.
Both sexes incubate the eggs. The male sits during the day, but both the male an female share sitting at night.
The nest is a loose platform made of sticks, which is usually placed on a horizontal forked tree branch.
