Habitat and conservation status
Its natural habitat is tropical moist lowland forest up to 1,200 m. It is often seen in lowland and foothill forest and secondary forest with bamboo,. The IUCN Redlist has classified this species as near threatened. Its threats are mainly habitat loss due to deforestation for lumber, mining and farmlands. There are no known targeted conservation actions for this bird, but it will indirectly benefit from the conservation of other North Luzon species like the Critically EndangeredIsabela oriole. The stronghold of the Isabela oriole in Baggao is being proposed as a protected area and will thus preserve key habitat for this beautiful babbler.[4]
