Chunky, medium-sized bird of lowland rainforest. Combination of mostly black plumage and coral-red bill is unique. Perches lethargically, twitching tail before flying out to grab large insects and small vertebrates from foliage. Frequently observed along forest edges; usually in the middle story or higher, but occasionally near the ground; sometimes follows army ants. Highly social; usually seen in groups of 2-5 birds. Loud, distinctive calls given by groups are heard more often than the birds are seen.
