Red-rumped Cacique Cacicus haemorrhous

Large cacique with a long, slender ivory bill. Found in the canopy of humid forests and may make migratory movements tracking the rains. Entirely black apart from a red rump that may be hard to see when perched. Note the blue eyes. Nests in colonies and builds large pendulous nests. The song is variable, including loud whistles and a harsh “kak-kak-kak” alarm call.
