The green-backed tailorbird (Orthotomus chloronotus), also known as the trilling tailorbird, is a species of bird formerly placed in the "Old World warbler" assemblage, but now placed in the family Cisticolidae. The bird is endemic to the Philippines on the Northern side of the island of Luzon. Its natural habitats are tropical moist lowland forests, tropical mangrove forests and secondary growth.
Region
Northern Philippines (Luzon)
Typical Environment
Occurs in the northern portion of Luzon where it inhabits lowland and foothill forests, mangroves, and dense secondary growth. It favors tangled understorey, thickets, bamboo patches, and forest edges. The species often ventures into scrub and semi-open areas near water and along forest margins. It remains close to cover and forages from near ground level up to the mid-storey.

Also called the green-backed tailorbird, it is famous for sewing leaves together with plant fibers or spider silk to form a cradle for its nest—hence the name “tailorbird.” Its fast, musical trills carry through thickets and are often the easiest way to detect it. The species adapts well to disturbed habitats and secondary growth, provided dense understorey remains.
Temperament
active but skulking
Flight Pattern
short, low flights with rapid wingbeats
Social Behavior
Usually seen in pairs or small family groups and maintains territories during the breeding season. The nest is a classic tailorbird leaf-cradle sewn together with fibers and spider silk, placed low in shrubs. It is presumed largely monogamous, with both parents attending the nest.
Migratory Pattern
Resident
Song Description
A rapid, bright series of high-pitched trills delivered repeatedly from concealed perches. Calls include sharp chip and tzik notes, often given while moving through dense cover.
