White-winged Triller and White-shouldered Triller are considered conspecific (as White-winged Triller L. sueurii) by Boles and Cristidis, Birds Australia and Clements (2010). Dickinson (2003) and Gill and Donsker (2010) (and Opus) recognise two separate species.
They can be found in open forest, woodland, scrub and savanna; also in overgrown and lightly wooded cultivated areas.
There is no detailed information, but it is presumed that they eat insects, which they forage for in short grass.
