Habitat

Sparsly vegetated rocky country with granite outcrops along rivers. Also near tracks are fresh burnt ground.

Reproduction

Eggs are laid in a slight depression of the bare granite rock, exposed to full sunshine or on litter of dead plant material near vegetation, shaded by
overhanging branches. Their eggs are laid on the ground. Clutches consist of I or 2 eggs incubated by male and female, and both care for the young. Fledging is estimated at 14 days, young leave the nest site within 16-18 days. Eggs are cryptically colored and slightly glossy, with a creamish to pinkish buff ground color and brown spots overlaying brownish spots and blotches. At hatching, the semiprecocial young have open eyes and are covered with cryptically colored down. Both on open granite rock and on litter, they blend well with their surrounding. During brooding injury-feigning displays are given readily; the parents grovel on the ground with drooping wings trying to lure the intruder away from the egg or young.

Feeding habits

During daylight hours, they roost on the ground or low in vegetation, often
in open situations exposed to full sunshine. During twilight and nighttime hours they become active, feeding entirely on night-flying insects. Forages over rocky outcrops and above tree canopy.

Conservation

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
