holub pembský Treron pembaensis

A medium-sized, chunky pigeon that has an olive-green back and a gray head and underparts. Flight is fast and direct. Sometimes seen alone, though more often in small groups. Found in forest, forest edge, plantations, and villages, often around fruiting trees. Similar to other green-pigeons, but easily separated by range, as it is the only green-pigeon on the island of Pemba. Voice is a quiet but maniacal series of sputters, whistles, and cackles.
