ThePhilippine creepers orrhabdornises are smallpasserinebirds and form thegenusRhabdornis. They areendemic to thePhilippines. They do notmigrate, other than to make local movements.
The relationship of the Philippine creepers to other bird species was formerly uncertain and the genusRhabdornis was placed in its own family Rhabdornithinae.[3][4]Molecular phylogenetic studies have revealed that the Philippine creepers are aberrant members of the starling familySturnidae.[5][6][7]
The Philippine creepers are similar in appearance totreecreepers (Certhiidae). They have thin pointed down-curved bills, which they can use to extricate insects from bark, but they have brush-like tongues, which enable them to also feed on nectar.
