White-winged Trillers are fairly common in woodland, and open scrub through most of their range, and close to riverbeds in the central arid zone. The conspicuous male bird—black above and white below in breeding plumage—trills cheerfully through much of the day during the breeding season (mid-spring to early summer), frequently rising on fluttering wings in song flight.

The female is similarly patterned but in dull fawns and white. In the non-breeding season, male birds appear similar to the female, retaining blackish feathers only on the wings and tail.

Typically 16 to 18 cm long, White-winged Trillers eat a variety of insects, which are taken on the ground, from in foliage, or in the air.
