Description and taxonomy
editEBird describes the bird as "A fairly small, long-tailed bird of montane forest undergrowth. Dark brown above with an orange-brown belly, a gray chest, a white throat and eyebrow, mainly in front of the eye, and a long graduated tail which it often holds cocked. Very skulking. Similar to Benguet and Philippine Bush-Warblers, but has a longer tail and deeper brown belly. Song is a sharp “tik!” followed by a ringing high-pitched buzz."[2]
Three subspecies are recognised:
- L. c. caudata– all of Mindanao except the Zamboanga Peninsula ; Longer tail
- L. c. malindangensis – west Mindanao in the Zamboanga Peninsula - Darker sides on face and a whiter throat
- L. c. unicolor – Luzon ; Dark upperparts, rufous belly and a shorter tail
The birds in Luzon and Mindanao have vastly different calls and the potential of there is potential for these birds to be split into their own distinctive species.
These birds feed on small insects. Forages alone or singly.[3]
Habitat and conservation status
editIt occupies montane mossy forest above 700 meters above sea level.
IUCN has assessed this bird as Least-concern as a lot of its montane habitat is difficult to access and it is reasonably common within its wide range. However, it is still declining due to habitat loss through deforestation, mining, land conversion and slash-and-burn.
