Medium-sized gray bird (small for a cuckooshrike) with considerable geographic variation. Male averages darkest on the wings, throat, and breast, contrasting more heavily with the rest of the plumage than in the fairly uniform-looking male Indochinese Cuckooshrike. Female is pale gray with fine barring on the underparts. Undertail is black with white-tipped feathers concentrated at the end of the tail; does not appear as evenly graduated as in the larger Black-winged Cuckooshrike, and is less extensively white-tailed than Indochinese Cuckooshrike. Forages in the upper levels of forests and forest edge in lowland and hilly areas, often as part of mixed-species flocks. Song begins with a few clear tinkling notes, then transitions into a loud, insistent “jeh, jeh, jeh, jeh”.
