The Visayan rhabdornis (Rhabdornis rabori) is a species of bird currently placed in the starling family, Sturnidae. It is endemic to the central Philippines on the islands of Negros and Panay. It was previously considered a subspecies of the stripe-breasted rhabdornis.[2] It is found in tropical moist montane forest. It is threatened by habitat loss.


Description[]

EBird describes the bird as "A medium-sized bird of foothill and lower montane forest on Negros and Panay with an off-white throat, a white belly, brown upperparts, darker wings and tail, a black mask, a gray crown, and pale brown sides broadly streaked white. Often perches on dead branches. Similar to Stripe-sided Rhabdornis, but usually found at higher elevations, bill is shorter and thicker, and crown is gray rather than dark with white streaks. Voice includes high-pitched chips and squeals."[3]

Habitat and Conservation Status[]

It is found in sub-montane and montane primary and secondary forest, forest edge and occasionally in clearings with an altitude range of 800 to 1,700 meters above sea level. It It is often found on the upper levels of the forest strata in the canopy.[4]

IUCN Red List has assessed this bird as vulnerable with the population being estimated at 2,500 to 9,999 mature individuals. This species' main threat is habitat loss. Habitat loss on both Negros and Panay has been extensive. Primary forests have been almost totally destroyed on Negros (where just 4% of any type of forest cover remained in 1988) and Panay (where 8% remained). Habitat degradation, through clearance for agriculture, timber and charcoal-burning, continues to pose a serious threat to remaining fragments

Conservation actions proposed include to conduct surveys to determine the species's status in remaining forest on Negros and Panay. Increase protection of remaining forest.[5]
