Long-billed White-eye
Rukia longirostra
Bizarre and unique-looking white-eye, endemic to Pohnpei, in Micronesia’s Caroline Islands. Pale brownish-olive overall, with orange legs and a long curved bill; the two other white-eyes on the island, Pohnpei White-eye and Caroline Islands White-eye, are gray and yellow respectively, and both have short bills. Forages actively, often moving about quickly in small flocks in hilly and montane forests. Gives smooth, high-pitched descending “tseer” notes.

Behavior
Its natural habitats are subtropical or tropical moist lowland forest, and plantations. It is considered near-threatened by habitat loss.<p>It has a curious nuthatch-like behavior of creeping along large tree limbs, and seems particularly specialized in using its long, slightly decurved bill to extract arthropods from the severed ends of branches.

Ornate Melidectes
Melidectes torquatus
A common and fairly large honeyeater of lower and mid-montane forest and clearings. Distinctively patterned with a black back scaled white, white belly with black scalloped flanks, black breast band, black head with large-orange yellow eye wattle, black chin and a small red mark in the base of the bill. Other melidectes co-occur but are larger and none have the white belly and breastband. Call, a loud, hollow “chok!” often followed by a slightly raspy, hollow warble.

White-throated Caracara
Daptrius albogularis
Uncommon in southern Andes; range does not overlap with Mountain Caracara. Favors open habitats above treeline, but also ranges lower to scavenge at dumps and in farmland with open trees. Often associates with Chimango and Crested Caracaras at the dump outside Ushuaia, Argentina. Sails, soars, and tumbles easily on updrafts. Adult is handsome and strikingly patterned black-and-white with creamy white underparts and a bold white tail tip. Juvenile is rather similar to smaller Chimango Caracara, but distinguished by black (not pale) bill.

Green-throated Mango
Anthracothorax viridigula
Large, dark hummingbird found in coastal regions and along large rivers. Use caution eliminating the more widespread Black-throated Mango, which often occurs in the same habitats; female-plumaged birds in particular may not be safely separable. Found in mangroves, abandoned plantations, swampy forests, and urban areas, often at higher levels in flowering trees, where it feeds on nectar and hawks for tiny flying insects. In proper light, green throat of male is diagnostic. Tail color is useful if bird can be studied at length; Green-throated’s tail is mostly purple, with brownish central tail feathers (tail of Black-throated is more chestnut, but subject to variation depending on light).
