The gray-backed tailorbird (Orthotomus derbianus) is a species of bird formerly placed in the "Old World warbler" assemblage, it but now placed in the family Cisticolidae. It is native to the Philippine islands of Palawan, Luzon and Catanduanes.
Ebrd describes this species as "A small, long-billed, long-tailed bird of dense tangled undergrowth in lowland forest in southern Luzon and neighboring islands. Has olive-green wings, a pale belly, a gray back and rump, a gray chest and throat with streaks, a rufous cap and tail, and orange legs. Very similar to Green-backed Tailorbird, but has a gray back, throat, and lower belly. Voice includes an explosive note followed by a rattling trill: “plik! Brrrrrrrrrr!” [2]
Two subspecies are recognized:
In 1958, a specimen was collected on Palawan and there have been no records on the island since. It is presumed to be a result of some aberrant movement or an error. It is presumed to be an insectivore. It forages in the low undergrowth in tangled vines. [3]
It is endemic to the Philippines, ranging across most of the islands. Its natural habitats are tropical moist lowland forest and tropical moist montane forest as high as 2,480 meters above sea level.
It is assessed as a Least-concern species by the International Union for Conservation of Nature as it is fairly common in its range and tolerant of disturbed habitat.
The blue-headed fantail is a fantail endemic to the northern Philippines where it is found on the islands of Luzon and Catanduanes. Until recently, it was considered conspecific with the Tablas fantail and Visayan fantail.
The Philippine tailorbird, also known as the Visayan tailorbird or the Chestnut-crowned tailorbird is a species of bird formerly placed in the "Old World warbler" assemblage, but now placed in the family Cisticolidae.

The black-headed tailorbird, also known as the white-browed tailorbird, is a species of songbird in the cisticola family, Cisticolidae. First formally described by the Scottish ornithologist Arthur Hay in 1877, it is endemic to the southeastern Philippines, where it is found on the islands of Mindanao, Dinagat, and Siargao. It inhabits dense undergrowth in lowland forests at elevations of up to 1,000 m (3,300 ft). Black-headed tailorbirds show three distinct phenotypes, which correspond to different stages of maturity: adults have a 'black' phenotype, immature birds have a 'mottled' phenotype, and juveniles have a 'grey' phenotype. These phenotypes were previously incorrectly thought to be related to differences between the sexes or to represent different species.
