Hooded Warbler
Setophaga citrina
Rather small, yellow warbler that habitually flashes its white outer tail feathers. Males have distinctive black hood with yellow face; females duller with only a shadow of hood (some lack it completely). Most similar to Wilson's Warbler; always look for white in the tail on Hooded. Generally a bird of the understory in mature forest, often around patches of rhododendron. Song similar to Magnolia Warbler but stronger; "weeta-weeta-weeTEEyoo". Call sounds like two shot glasses being chinked together.
识别特征
The hooded warbler is a small bird and mid-sized warbler, measuring 13 cm (5.1 in) in length and weighing 9–12 g (0.32–0.42 oz). The hooded warbler has a wingspan of 6.9 in (17.5 cm). It has a plain olive/green-brown back and yellow underparts. Their outer rectrices have whitish vanes. Males have distinctive black hoods which surround their yellow faces; the female has an olive-green cap which does not extend to the forehead, ears, and throat. Males attain their hood at about 9–12 months of age; younger birds are essentially identical to (and easily confused with) females. The song is a series of musical notes which sound like: wheeta wheeta whee-tee-oh, for which a common mnemonic is "The red, the red T-shirt" or "Come to the woods or you won't see me". The call of these birds is a loud chip.

The French polymath Georges-Louis Leclerc, Comte de Buffon described the hooded warbler in 1779 in his Histoire Naturelle des Oiseaux from a specimen collected in Louisiana. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Muscicapa citrina in his catalogue of the Planches Enluminées.<p>The hooded warbler was formerly placed in the genus Wilsonia. A molecular phylogenetic study of the family Parulidae published in 2010 found that the hooded warbler was embedded in a clade that contained species then assigned to Dendroica as well as two of four species of Parula and the monotypic genera Catharopeza and Setophaga. To create a monophyletic genus, all members of the clade were placed in the expanded genus Setophaga, which under the rules of the International Code of Zoological Nomenclature, had priority. The genus Setophaga was introduced by the English naturalist William Swainson in 1827.The species is monotypic; no subspecies are recognised. The genus name Setophaga is from Ancient Greek ses, "moth", and phagos, "eating", and the specific citrina is Latin for citrine.

Rarotonga Starling
Aplonis cinerascens
A medium-sized gray and grayish-brown starling with a thin dark eye mask and a pale yellow eye. Prefers undisturbed montane forest above 150 meters of elevation, but occurs irregularly down to 30 meters. Pohnpei Starling is much smaller and uniformly matte grayish-brown with a dark eye. Rarotonga’s voice consists mostly of squeaks, whistles, and bell-like notes.
Marabou Stork
Leptoptilos crumenifer
This huge, macabre-looking stork has a massive dagger-like bill and naked pink head and neck that appear severely sunburned. A white ruff and loose inflatable skin on the neck add to its odd appearance. It soars effortlessly at great heights searching for food; note its white belly in flight. Marabous are equally content in wetlands or in dry bush; they are most frequently encountered lurking near carrion, as they attend kills of major predators and will opportunistically snatch scraps. They also readily scavenge around humans and waste dumps.
Ethiopian Cisticola
Cisticola lugubris
A relatively colorful, mid-sized, long-tailed cisticola. Note the gray-brown back with thick black streaks, the rufous on the wing and cap, and the whitish underparts. Tail is slightly longer in non-breeding plumage. Found in wetlands, moist grassland, and scrub. Similar to Stout Cisticola, but has a slimmer bill, longer tail, and brighter rufous wing panel. The vocalizations are quick bursts of rough calls, usually followed by the dry, trilling song.
