Males are grayish above with black wing tips, while their underparts are mostly white. Females are dark brown above with pale, heavily streaked underparts; from below, dark banding is evident on the underwing. Immatures are similar to females, but darker above with cinnamon below and streaked only on breast; wing linings are cinnamon.
females (up to 7 has been reported). The nest, built completely by the female, is a pile of small sticks and grass on the ground in dense grass, scrub, marshy growth, or cropland. This last location is risky, as the well-hidden nests are often run over by farm machinery. Clutch is 3-7+ eggs, depending upon available food supply, laid at intervals of 1-3 days. Breeding first occurs usually at 2-3 years of age; some breeding after the first year.
