Northern Silvery-Kingfisher
Ceyx flumenicola
A small, dashing kingfisher of forested lowland streams in the central Philippines. Overall dark blue in color, more purplish on the underparts, with a creamy throat, a cream-colored spot behind the cheek, an orange spot behind the nostril, a white belly, a pale silvery-blue stripe down the back to the tail, and whitish flecks on the head and wing. Legs bright red. Unmistakable. Voice is a simple, high-pitched “tseep,” often given in flight.

分布与栖息地
It appears to be reliant upon forested streams below 1,000 m and will tolerate secondary and selectively logged forest and even streamside vegetation within coconut plantations, close to forest edge.<p>IUCN has assessed this bird as near threatened with the population being estimatesd at 1,500 to 7,000 mature individuals. 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.<p>Extensive lowland deforestation throughout its range is the chief threat. Only 4% forest cover is estimated to remain on Bohol. Most remaining lowland forest is leased to logging concessions or mining applications. Watercourses with high siltation loads, resulting from deforestation, appear not to hold the species, and riverine pollution is likely to have a similar impact. Tree-cutting, agricultural expansion, including pesticide (specifically Carbofuran) contamination from commercial growing of banana, and soil erosion are all threats to Rajah Sikatuna National Park (Bohol), a key sites for the species. Conversion of terminalia forest into rice fields and oil palm plantation is driving habitat loss elsewhere. Current laws protecting riverine habitats are weak and require revision.

其他鸟类
Amazonian Parrotlet
Nannopsittaca dachilleae
Rare, short-tailed parakeet. Small and green, with a light bluish wash on the face. Sexes similar. Compared to the similar (and usually more common) Dusky-billed Parrotlet, note the absence of a blue rump patch (also missing on female Dusky-billed), bluish face (green or yellow in Dusky-billed), and light pinkish bill. Likes to feed on seeding bamboo, and most often found in areas with extensive bamboo or in secondary forest along rivers. Flight calls are high tinkles that are lower and less metallic than Dusky-billed Parrotlet calls.
Chatham Islands Petrel
Pterodroma axillaris
Gadfly petrel of medium size. Dark gray upperparts and white below with a diagonal black bar from the edge of the wing to the black base of the underwing. Has a black bill, a dark eye-patch, and pink legs and feet. Breeds only on the Chatham Islands, but can forage up 3000 km offshore. Migrates to deep waters off the South American coast. Distinguished from Black-winged Petrel by the reduced black bar on the underwing; Mottled Petrel is similar but larger, with a dark belly, lacking the diagonal bar on the wing.
Rio Suno Antwren
Myrmotherula sunensis
Scarce and confusing antwren of lowland rainforest; known from scattered locations throughout the western parts of the Amazon basin. Male is gray with a black bib and white spots on the wings that usually form bars. Female is mostly brown and extremely difficult to separate from several other antwren species. Male is told from male Long-winged Antwren by gray (not whitish) belly, lack of a distinct white tip to the tail, and smaller wing dots. No overlap with the similar Slaty Antwren, which is found at higher elevations. Usually encountered with mixed-species understory flocks, often with other species of antwren. Song is a series of three to five drawn out “swee” notes.
