Medium-sized gray bird with a black cap and carrot-colored bill. Found in virtually all habitats with a woody component, including forest, scrub, villages, and plantations. Often in groups, and occasionally joins mixed feeding flocks with other bird species. Vocal bird that frequently gives a whining call and a long rattling song. Similar in size to Madagascar Cuckooshrike, but has an orange bill and a black cap rather than a dark hood. Gray underparts separate Malagasy Bulbul from all vangas.
