Phoenix Petrel
Pterodroma alba
A long-winged petrel, predominantly dark with a gleaming white belly. Throat patch often shows pale speckling, and birds sometimes appear distinctly pale-throated. Key identification feature is the prominent pale bar at the leading edge of the dark underwing between the elbow and body. Similar in pattern to Tahiti Petrel, but much smaller-billed and sometimes shows a pale throat. Usually flies with wings bent at the elbow, unlike the remarkably straight-winged Tahiti Petrel. Silent at sea.

The Phoenix petrel was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the other petrels in the genus Procellaria and coined the binomial name Procellaria alba. Gmelin based his description on the "white-breasted petrel" that had been described in 1785 by the English ornithologist John Latham from a specimen belonging to the naturalist Joseph Banks. The type locality is Kiritimati (Christmas Island) in the Pacific Ocean. The Phoenix petrel is now one of 35 species placed in the genus Pterodroma that was introduced in 1856 by the French naturalist Charles Lucien Bonaparte. The genus name combines the Ancient Greek pteron meaning "wing" with dromos meaning "racer" or "runner". The specific epithet alba is from Latin albusmeaning "white". The species is monotypic: no subspecies are recognised.

Black-and-buff Woodpecker
Meiglyptes jugularis
Adorably tiny and stout woodpecker. Triangular crest makes the head seem disproportionately large at a distance. Odd patchy black-and-white patterning is unique and easily recognizable. Male has a subtle reddish tinge to the bill base, but the two sexes are otherwise quite similar. Inhabits lowland to foothill forests, where it prefers open patches and edges. Forages in pairs or singly, poking about on slender branches and around leaf clusters. Gives a squeaky two-note call and a high-pitched rattling trill.

Malayan Banded-Pitta
Hydrornis irena
Broad red-orange eyestripe glows like lava on this shy, jewel-like bird. Male has deep blue underparts with thin tiger-like barring on the sides of the chest. Female is pale below with fine dark barring. Forages quietly on the floor of dense lowland forests. Most common calls are a quiet roar and a short, descending “pr-r-r-r-r”.

Palm Tanager
Thraupis palmarum
Large, plain tanager, gray overall with hints of olive-green in good light; note contrasting black wings with paler patch at base of primaries. A habitat generalist often found around palm trees and in open shrubby areas, gardens, and forest edges. Usually in pairs or small flocks, sometimes with other species. Often quite noisy and conspicuous; gives a series of sputtering squeaks or a single nasal “swee?”
