Lorentzdickkopf Pachycephala lorentzi

A medium-sized bird of montane forest. Male and female look the same. Yellow belly, olive back, dark gray head, pale gray breast and whitish throat. Very similar to Vogelkop Whistler which does not co-occur. Similar to the female Regent Whistler, but Lorentz’s has a plain gray rather than scaled throat and a gray rather than olive chest. Typical whistler song with forceful, up-and-down whistled notes, some with an explosive quality.
