An enormous pigeon of the southern lowland rainforests. Erect, mohicanlike crest is especially long at the back. Blue-gray body with maroon on shoulder and chest, up to the throat. Very large white patch can reach the edge of the wing. Has a deep-bellied appearance and twitches the tail nervously. Forages in small groups on the forest floor. Unmistakable and does not overlap with other crowned-pigeons. Call, loud 2-note booming, sounding like a beating heart.
