Seram Mountain-Pigeon
Gymnophaps stalkeri
A very distinctive large, long-tailed pigeon from the island of Seram. Shows a pale gray crown and neck, an extensive reddish bare skin mask around the eye, a yellow-orange bill with a red base, a pale pinkish throat and chest, and a burgundy belly. Upperparts light gray with a subtle greenish cast. Singles and pairs occur in forested foothills, typically at subcanopy and canopy level; groups gather in fruiting trees. No similar species occurs on Seram. The call of this recently-described species is currently unknown.

The Seram mountain pigeon is a medium-sized pigeon that is 33–38.5 cm (13.0–15.2 in) long and weighs 330–338 g (11.6–11.9 oz). It has a deep buff-pink face and breast, paler on the chin, changing to wine-pink on the underparts. The thighs are grey and the nape, crown, and back of neck are pale, pure blue-grey, while the belly and underside of the tail are dark chestnut with wine-grey fringes to the feathers. The eyes are scarlet to yellow with purplish red to scarlet orbital skin, the bill is yellow with a purple cere, and the legs are purple. Juveniles have browner upperparts, have browner underparts, and are darker below the tail. They also have dull red orbital skin, dull red legs, and a white-tipped grey bill with a dull red cere.
分类信息
The Seram mountain pigeon was described as Columba stalkeri by the Scottish ornithologist William Ogilvie-Grant in 1911 on the basis of specimens from the Kanobi Mountains on Seram, Indonesia. It was subsequently merged with the Buru mountain pigeon in the genus Gymnophaps by the Australian amateur ornithologist Gregory Mathews in 1927. It was again split as a distinct species on basis of differences in appearance in 2007 by Frank Rheindt and Robert Hutchinson.<p>The generic name Gymnophaps is derived from the Ancient Greek words γυμνος (gumnos), meaning bare, and φαψ (phaps), meaning pigeon. The specific name stalkeri is in honour of Wilfred Stalker, an Australian natural history collector who collected the type specimens of the species on a British Ornithologists' Union expedition. Seram mountain pigeon is the official common name designated by the International Ornithologists' Union. Other common names for the species include Seram long-tailed mountain-pigeon.<p>The Seram mountain pigeon is one of four species in the mountain pigeon genus Gymnophaps, which is found in Melanesia and the Maluku Islands. It forms a superspecies with the other species in its genus. Within its family, the genus Gymnophaps is sister to Lopholaimus, and these two together form a clade sister to Hemiphaga. The species has no subspecies.

African Shrike-flycatcher
Megabyas flammulatus
A distinctive shrike-like bird of forest and forest edge, often seen perched upright on branches wagging its tail from side to side. Looks like a heavyset flycatcher with a large hooked bill, a big head, a relatively short tail, and a large body. Males are typically white below and black above with a red eye and a white rump patch. Females are white below with strong black streaking and white lores, and generally reddish-brown above with darker primary flight feathers. Similar to Black-and-white Shrike-Flycatcher, but African Shrike-Flycatcher has a white throat and no crest, and females have streaked undersides. Calls include a descending “PWHEEEeeeer,” single “cherdew” calls, and doubled sets of variable, almost mechanical phrases: “perit-perit, tchledew-tchledew.”.
Ring-billed Gull
Larus delawarensis
Fairly small gull, common and widespread throughout most of North America. Breeding adults are white-headed with a bold black ring around the bill; nonbreeding adults have smudgy brown markings on the head. Note pale eye and yellow legs. Immatures are mottled brownish overall; note pink bill with black tip. Found along lakes, rivers, ponds, and beaches. More common inland than most other gull species, and quite fond of parking lots and urban areas. Often in flocks. Most similar to Short-billed Gull, but larger and larger-billed. Immatures of the two species are especially difficult to differentiate, but Ring-billed is usually more coarsely mottled.
Copper-tailed Hummingbird
Saucerottia cupreicauda
This hummingbird is found in humid forest in mountainous regions of eastern Venezuela, the Guianas, and northern Brazil. Plumage is bright green with a coppery rump and tail, and belly ranges in color from pale gray to buff. Occasionally seen in lowlands, where it is perhaps just a seasonal visitor or wanderer. Formerly considered to be a subspecies group of Green-bellied Hummingbird.
