The green-faced parrotfinch (Erythrura viridifacies) is a rare species of estrildid finch found in northern Philippines, on Luzon, Mindoro, Panay, Negros and Cebu islands. It is an elusive and nomadic bird with mostly green plummage with a bright red vent and tail, rarely seen but large flocks of up to 1,000 birds have been reported feeding on bamboo flowers. Its local name is mayang-kawayan in Tagalog which roughly translates to bamboo sparrow due to its association with bamboo flowering. It is listed as vulnerable on the IUCN and is threatened by habitat loss, deforestation and the illegal cage bird trade.
