Gray-cheeked Green-Pigeon Treron griseicauda

Chunky green pigeon with comical lime-green “goggles” and a thick white bill. Male has a dark maroon back and shoulders, which the female lacks. Both sexes have a silvery-gray forehead and crown. Female may be confused with female Pink-necked and Orange-breasted Green-Pigeons, but note her gray crown, green spectacles, and bright yellow-green wing feather linings. Inhabits a wide range of wooded areas, from the lowlands into the foothills. Often in pairs, but will also gather in large flocks at fruiting trees. Gives a long, quavering coo, as well as more even-sounding cooing and odd chuckling calls.
