Fairy Gerygone
Gerygone palpebrosa
Small plain bird with thin bill. Upperparts grayish brown with green tinges, underparts yellow. In male, distinct white facial markings extend from above the base of the bill to the chin. In female and juvenile, facial markings indistinct, usually just a light loral patch (above bill). Compare larger Green-backed Honeyeater, with pale eye and dark lores. Inhabits subtropical wet forests, usually edges and surrounding habitats, and mangroves.
识别特征
Adult birds have olive upperparts and yellow underparts, brownish tails, short black bills and legs, and red eyes. The male has a black throat. The subspecies flavida can be distinguished from subspecies personata by the white tip of its tail.
分类信息
Alfred Russel Wallace described the species as Gerygone palpebrosa in 1865, from a specimen from the Aru Islands. The species name is derived from the Latin palpebra "eyelid", for the bird's facial markings. A taxon known commonly as the fairy warbler, Gerygone flavida was described from the Herbert River in Queensland and initially treated as a separate species. However, birds further north along the Queensland coastline became gradually more like Gerygone palpebrosa, indicating there was no delineation between the two forms. This and the similarity of their songs indicated they were a single species.<p>Other common names recorded include black-throated, black-headed or masked gerygone, warbler or flyeater, hornet-nest bird, from a propensity to nest near wasp nests. These names were applied to what was thought a separate species—Gerygone personata described by John Gould in 1866—from far north Queensland which has been sunk into this one. What was described as Gerygone flavida was given the names yellow warbler/gerygone/flyeater, Cardwell gerygone or Herbert River flyeater.<p>Genetic study indicates that the fairy gerygone is most closely related to the green-backed gerygone (Gerygone chloronota), their ancestors having diverged around two million years ago.<p>Six subspecies are recognised:

分布与栖息地
It is found in Australia, Indonesia, and Papua New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests.<p>The fairy gerygone is listed by the IUCN as being of Least Concern. No particular threats have been identified and the bird has a wide range and stable population.

行为
Male fairy gerygones hold themselves erect and sing a loud melodious song when they hear the calls of predators, particularly their main predator the black butcherbird. The purpose for this is unclear, though it is possibly a form of advertising to potential mates, promoting the male's prowess at singing in times of danger.<p>The fairy gerygone nests near wasp nests, possibly to keep itself safe from predators.

South American Painted-Snipe
Nycticryphes semicollaris
Distinctive and attractive, but a rarely seen denizen of fresh and brackish wetlands, especially with shallow water and low to knee-high grasses; also found on lakeshores with taller reeds and rushes. Occasionally seen feeding quietly at edge of vegetation, but mostly seen when flushed from close range. Flies up silently with stiff flicking wingbeats and brief glides, long legs trailing, and drops back to cover usually not far away. Note bold white spots on wings and droop-tipped bill. Related to jacanas, not closely related to the typical snipe.
Leaden Flycatcher
Myiagra rubecula
A long-tailed, slender songbird with fine bill. Males rich blue-gray above, white below, with a blue-gray bib with convex lower edge (curves upward at the edges). Crown paler than throat, lending male a bearded appearance in optimal light. Male Satin Flycatcher has uniformly dark head, blackish (not grayish) tail feathers, and concave bib edge. Female paler blue-gray above, with pale orange throat and breast. Inhabits varied woodlands, perches high in the canopy, often shakes the tail rapidly. Song a repeated two-note whistle; call a loud buzzing “zerp.”
Mindanao Cuckooshrike
Coracina kochii
Burly gray cuckooshrike with dark eyes and a heavy bill. Endemic to the southern and east-central Philippines, from Bohol east to Samar, and south to Mindanao and Basilan. Both male and female are gray above and barred black-and-white below. Inhabits lowland and foothill forest and forest edge, where forages at middle and upper levels, sometimes associating with other species. Gives a range of high-pitched and scratchy calls, including doubled screeching notes: “whee-wheet!” Formerly treated as part of a more broadly-defined “Bar-bellied Cuckooshrike”.
