The Sulu jungle flycatcher (Cyornis ocularis) is a species of passerine bird in the Old World flycatcher family Muscicapidae. It is endemic to the Sulu Archipelago. Its natural habitat is tropical moist montane forests. While it has yet to be assessed by the International Union for Conservation of Nature, this species is likely threatened by habitat loss.

The Sulu jungle flycatcher was split from the rufous-tailed jungle flycatcher (Cyornis rufocauda) as distinct species by the IOC in 2021.[1]
Description and taxonomy
editEBird describes the Chestnut-tailed jungle flycatcher species complex as "Drab, medium-sized flycatcher with a long slender bill. Ranges from the southern Philippines to Borneo. Appearance differs across its range, but always look for a warm rufous tail, white throat, and diffusely brown-washed chest. Found in lowland and foothill forest in the Philippines, and in submontane and montane forest in Borneo. Makes forays from a low perch in the understory or forest edge. Song is a series of high and squeaky notes, often interspersed with buzzes.!”[2] This bird is differentiated from its sister species as it has a prominent rufous eyering, light brown upper mandible and paler brown lower mandible, and pinkish legs. [3]
This species was previously placed in the genus Rhinomyias but was moved to Cyornis based on the results of a 2010 molecular phylogenetic study.[4][5] The Sulu jungle flycatcher (C. ocularis), which is endemic to the Sulu Archipelago, and the Crocker jungle flycatcher (C. ruficrissa), which is endemic to Borneo, were split as distinct species by the IOC in 2021. With the split, this species was renamed from rufous-tailed jungle flycatcher to Philippine jungle flycatcher.[5]
Habitat and conservation status
editIt is found in tropical moist lowland forest.
IUCN has yet to assess this bird as it does not yet recognize it as a separate species. All other birds endemic to the Sulu Archipelago are endangered species due to the deforestation that has occurred in the past decades. Due to this, as this species is also forest dependent, it is highly likely that it is threatened.[6]
