The brown songlark forages on the ground, walking, running and hopping as it searches for food (2). Its diet includes a range of small invertebrates and their larvae, and this species also eats small seeds (2) (4) (5) (6). If disturbed, the brown songlark typically flies low before diving into cover with its tail raised, and it usually roosts on the ground under cover (2).
The breeding season of the brown songlark runs from around August or September to February (2) (3) (6). Outside of the breeding season this species is either solitary or occurs in scattered flocks (2), but when breeding the males become highly territorial, performing conspicuous song-flights or singing from a prominent perch with the tail held high and the wings drooping (2) (3). The female brown songlarks nest within the males’ territories (3), and each male may mate with several females (2) (3).
The female brown songlark constructs the nest, which is built in a small depression in the ground and consists of fine dry grasses. The nest is usually well hidden at the base of a grass tussock or small shrub, and is lined with fine grass or hair. Two to five eggs are laid, and are incubated by the female alone. The eggs hatch after 11 to 13 days and the chicks leave the nest at 10 to 14 days old. The female is mainly responsible for feeding the chicks, but the male may occasionally assist (2) (3).
If the nest is predated, for example by a fox or snake, the female brown songlark can lay a replacement clutch of eggs. Some females also go on to lay a second clutch after successfully raising an earlier brood of chicks (2) (3).
