Negros Striped-Babbler
Zosterornis nigrorum
A fairly small bird of lower-elevation montane forest and degraded habitat on Negros. Warm brown above and cream-colored below with fine black streaks. Note the white throat, the small white area around the eye bordered black, and the black line through the eye. Often found in mixed-species flocks. Somewhat similar to Stripe-sided and Visayan Rhabdornises, but smaller, with a white face rather than a broad black band through the eye. Voice includes high-pitched chipping notes.

EBird describes the bird as "A fairly small bird of lower-elevation montane forest and degraded habitat on Negros. Warm brown above and cream-colored below with fine black streaks.

Somewhat similar to Stripe-sided and Visayan Rhabdornises, but smaller, with a white face rather than a broad black band through the eye. Voice includes high-pitched chipping notes."<p>It looks extremely similar to the closely related Panay striped babbler, with the differences being that the Negros striped babbler has more light and finely streaked underparts, a more distinct mask and overall lighter appearance.

分布与栖息地
It inhabits montane forest between 950 and 1,600 m, chiefly occurring between 1,050 and 1,400 m, generally favouring the lower storey. It seems to tolerate degraded habitats, having been recorded in recently degraded forest, secondary forest and dense bushes at the forest edge and in forest opened up for agriculture. However, it appears to be limited to areas with some remaining forest cover.<p>IUCN has assessed this bird as Endangered. This species' main threat is habitat loss with wholesale clearance of forest habitats as a result of logging, agricultural conversion and mining activities occurring within the range. By 1988, Negros only had 4% forest cover remaining and reached 1,250 m on Mt. Talinis, one of its key habitats. Among the other four striped babblers (Panay striped babbler, Palawan striped babbler and Luzon striped babbler), this bird is the most endangered with population being estimated to be just 600 - 1,700 individuals. This is due to Negros Island being one of the most deforested islands in the country and thus has a lack of suitable habitat.<p>The Mount Talinis /Balinsasayao Twin Lakes Natural Park area has been proposed for conservation funding. This area includes about 40 km2 of high-altitude forest, which affords indirect protection through the Negros Geothermal Reservation. Environmental awareness campaigns have been conducted near Mount Talinis itself. Mount Kanlaon is also a protected area if the babbler still persists there.

Gray-winged Blackbird
Turdus boulboul
A large forest thrush whose name describes its key feature; males are black and females are brown, but both have flashing silvery wings. Bright orange bill and eyering are eye-catching in dark forests. Forages quietly in the understory of montane and submontane broadleaf evergreen forests. Often solitary, occasionally in flocks in the winter. Tends not to visit gardens and parks like Tibetan and Chinese blackbirds, but does occasionally visit feeders at hides. Sweet, “thrushy” song consists of warbled phrases, sometimes with a slightly scratchy quality.
African Skimmer
Rynchops flavirostris
Distinctive tern-like bird with long wings, a short tail, and a bizarre bill in which the upper mandible is shorter than the lower mandible. In slow flight, shows a very white underwing and a white stripe along the back of the upperwing. Feeds by skimming its knife-like lower mandible through the water and snapping up small fish that it makes contact with. Found very locally on sandbars in lakes and rivers. Call is a husky “chep.”
Gray-backed Shrike
Lanius tephronotus
Found in forest edge, farmland, and plains, this adaptable and elegant small shrike is a common sight across much of its range. Gray crown and back contrast sharply with white throat, black mask and wings, and bright orange sides. Noticeably smaller than Long-tailed Shrike, with which it shares its range; unlike that species, lacks orange on the back. Regularly perches on exposed perches such as telephone lines, posts, and snags. Song musical and variable, a series of buzzy, whistled, and warbled notes; incorporates mimicry of other species. Calls include repeated harsh chattering notes, as well as high barking and piping notes.
