Polynesian Storm-Petrel

Nesofregetta fuliginosa

A very large storm-petrel with large broad wings and a long forked tail. White rump and throat patch are often strikingly obvious, even with brief views. Pelagic, but occurs in groups near colonies. Combination of stark black-and-white plumage, relatively large size, white throat patch, and long gliding flight with periodic surface bounces is diagnostic. Silent at sea.

分类信息

The Polynesian storm 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 fuliginosa. Gmelin based his description on the "sooty petrel" that had been described in 1785 by the English ornithologist John Latham in his book A General Synopsis of Birds. The Polynesian storm petrel is now the only species placed in the genus Nesofregetta that was introduced in 1912 by the Australian born ornithologist Gregory Mathews. The name combines the Ancient Greek nēsos meaning "island" and Fregetta, a genus name that was introduced by Charles Lucien Bonaparte in 1855 for the storm petrels. The specific epithet fuliginosa is from Late Latin fuliginosus meaning "sooty". The species is monotypic: no subspecies are recognised.

保护状况

Some of the conservation efforts for the Polynesian Storm-petrel include monitoring breeding populations and invasive species in specific areas, restoration of former breeding islands, and using translocations and social attraction to restore populations.<p>A few of the efforts from the past, starting from 1990 includes predator removal, biosecurity plans, and compliance and education.

Crimson-backed Flameback

Crimson-backed Flameback

Chrysocolaptes stricklandi

Large, spectacular woodpecker with crimson upperparts, black-scaled pale underparts, and a crested head. Males have a red crest, females a black crest with fine white markings. Endemic to Sri Lanka. Typically in pairs, in the understory of forests and woodlands, where it regularly joins mixed species flocks; can also occasionally be found in disturbed areas or home gardens. Note the pale ivory colored bill, and lack of a prominent white eyebrow, unlike the similar Red-backed Flameback. Also note a distinctive elliptical marking on the face below the eye, which distinguishes this flameback from all other flamebacks on Sri Lanka. Frequently given call is a rapid, fast-paced, high-pitched trill, usually getting quieter and decelerating at the end. A fast-paced, descending drum is also given regularly; both the call and drum are different from that of the more common Red-backed Flameback.

Short-tailed Woodstar

Short-tailed Woodstar

Myrmia micrura

Tiny hummingbird with a very short tail found in arid scrub and desert in western Ecuador and northwestern Peru. Male has glittering violet “beard” that is bordered by white above and below. Female lacks throat patch and has a buffy tinge to underparts, faint facial stripes, and a white tip to the tail. Female is told from other similar species in range by very short tail that does not reach wingtips when perched and white tip of tail (not white edges or corners).

Blue-winged Pitta

Blue-winged Pitta

Pitta moluccensis

A beautiful, rainbow-colored inhabitant of tropical forests; often bolder than other pittas and occasionally seen in city parks, especially while on migration. Stunning, with green back, blue wings, orange belly, and black mask. Solitary outside of the breeding season; usually seen hopping around in leaf litter and turning over debris in search of invertebrates. Listen for its bouncy song, a series of loud “weuh-wheew!” phrases.
