Magenta Petrel
Pterodroma magentae
One of the rarest seabirds in the world, endemic to the Chatham Islands. Medium-sized bird with a distinctive dark gray head, neck, and upper breast and a gray chin. The rest of the underside is white with a light gray underwing. During breeding, the birds mainly forage south and east of their colonies, venturing across the Pacific Ocean to South American and tropical seas in the winter. Many petrel species can appear similar to the Magenta Petrel but can be ruled out if they appear partially hooded, show traces of an “M” across their back, or are found outside of the Chatham Island range during breeding season.
识别特征
This medium-sized petrel has a brownish-grey head, neck, and upper breast, with white underparts. The undersides of the wings are brown. It has a black bill and pink legs. Adults weigh 400–580 g.<p>The bird nests in 1–3 m long burrows under dense forest. They form long-term monogamous pair bonds, raising one egg at a time, and both partners incubate the egg and feed the chick. The breeding season is between September and May, during which time the birds forage over the open ocean.

Collared Imperial-Pigeon
Ducula mullerii
The large, nomadic pigeon of mangroves and riverine forests. Note the distinctive, full black collar that narrows at the front and meets the maroon back. Black tail with white band across. Small flocks often seen in flight or perched up on exposed branches. Unmistakable when seen perched, but in flight similar to Pinon’s Imperial-Pigeon. Collared Imperial-Pigeon is much more likely in mangroves. Call, a deep, muffled “woo-oo pooo” with the first 2-note call falling and the last, lower in pitch.

Band-tailed Barbthroat
Threnetes ruckeri
Scarce hummingbird of humid evergreen forest and edge in tropical lowlands. Favors shady understory, especially with Heliconia flowers. Usually visits flowers briefly and whips away with a sharp buzzy squeak. Note long arched bill (yellowish below), striped face, blackish throat patch, and rusty breast patch. Striking tail pattern, black with white tips, and a white base that is only readily seen when the tail is spread.

Masked Apalis
Apalis binotata
A small, slender warbler with greenish upperparts and reddish eyes; gray crown and cheeks are separated from the black throat by a striking white moustache. Juvenile has a green crown and a yellow throat. Locally common at scattered locations in lowland forest below 1500 meters of elevation, preferring the lower strata of primary and secondary forest and scrub in clearings. Pairs give a continuous buzzy “dree-lip, dreep-lip, dree-lip” and a dry “strik-strik-strik.” Masked Apalis looks similar to some montane forest apalises, but Black-throated Apalis has a striking yellow-orange belly, and Black-faced Apalis, an Albertine Rift endemic, has a black crown and the moustachial streak reduced to a neck spot.
