ハゲクビカザリドリ Gymnoderus foetidus

Unusual medium-sized bird of forest canopy in Amazonia. Dark blue overall with bare, wrinkly blue skin on the neck and a pale bill. Males have pale gray wing patches. Perches at the tops of trees in the rainforest canopy and is frequently seen flying across rivers and forest clearings. In flight, often holds its neck outstretched with small head drooping slightly. Sometimes can seem to disappear from a site for periods of time, as it is partly nomadic and follows seasonal fruiting events.
