white-browed shama (''Copsychus luzoniensis'').
Description and taxonomy
Described on ebird as "A medium-sized, long-tailed bird... Black on the upperparts and tail, with a white belly and pale pink legs. Male has a black throat and chest. Female has a rufous patch on the rump and lower back, and a white throat with a black breast band. Somewhat similar to
Philippine magpie-robin, but has a long white eyebrow and no white wing patch. Heard more often than seen. Gives a very varied song, with loud melodic whistles, warbling trills, and repeated loud “chew chew chew!” notes."
It was previously conspecific with the
White-browed shama but it differs in molecular genetics, vocally, an all black rump, wings and tail, lacking the
White-browed's white wingpatch, shorter tail and longer legs.
Ecology and behavior
Not much is known about the diet but also presumed to feed on a typical shama diet of insects. Usually seen in pairs foraging close to the forest floor or thickets with a lot of tangled vines.
Nothing is known about its breeding habits.
