The Philippine bush warbler, also known as the Luzon bush warbler, is a species of bird in the family Cettiidae. It was formerly conspecific with the Japanese bush warbler. It is found only in the Philippines in the Cordillera Mountain Range of northern Luzon. It is found in tropical montane forest.
Region
Southeast Asia
Typical Environment
Restricted to the highlands of northern Luzon in the Philippines, mainly within the Cordillera Central. It inhabits dense understory of montane and mossy forests, often along edges, clearings, and bamboo thickets. The species also uses regenerating secondary growth and brushy ravines, typically keeping close to the ground. It favors areas with thick leaf litter and tangled shrub layers, where it forages and nests.
Altitude Range
1000–2600 m

Highland

Also called the Luzon bush warbler, this shy understory specialist was formerly lumped with the Japanese bush warbler but is now recognized as a distinct endemic of northern Luzon. It keeps to dense vegetation, where it is more often heard than seen, giving a loud, ringing song. It frequently cocks its tail while moving mouse-like through thickets. Its persistence in secondary growth suggests some tolerance to habitat changes, though intact montane forest remains important.
Temperament
secretive and skulking
Flight Pattern
short rapid wingbeats, low and direct through cover
Social Behavior
Typically solitary or in pairs, maintaining small territories in dense understory. Nests are placed low in thick vegetation or near the ground, likely a cup or domed structure concealed in tangles. Breeding pairs are monogamous, with the male advertising territory by persistent song. Outside breeding, it may loosely associate with mixed-species flocks at low levels.
Migratory Pattern
Resident
Song Description
A loud, ringing series of clear whistled notes and short phrases, often repeated from concealed perches. Calls include sharp ticks and thin seep notes given while moving through cover.
