Fulmar Prion
Pachyptila crassirostris
Small to medium-sized prion with dark “M'' stretched across back from wingtip to wingtip, noticeable in flight. Fulmar Prion has poorly defined facial markings and a broad, dark tip to the upper tail. Breeds on the Chatham Islands, New Zealand Subantarctic Islands, and Heard Island. Relatively sedentary and usually only seen around breeding colonies year-round. Very similar to the more abundant Fairy Prion and generally only distinguishable when in the hand. Fulmar Prion has a heavier bill with a larger hook and slightly darker tip to the underside of the tail.
识别特征
The fulmar prion (Pachyptila crassirostris) is a species of seabird in the family Procellariidae, found in the southern oceans.
分类信息
The fulmar prion is a member of the genus Pachyptila – and along with the blue petrel – makes up the prions. They in turn are members of the family Procellariidae and the order Procellariiformes. The prions are small and typically eat zooplankton; however, as a member of the Procellariiformes, they share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns, although the nostrils on the prion are on top of the upper bill. The bills of Procellariiformes are also unique in that they are split into between 7 and 9 horny plates. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as an energy-rich food source for chicks and for the adults during their long flights. Finally, they also have a salt gland that is situated above the nasal passage and helps desalinate their bodies, due to the high amount of seawater that they imbibe. They excrete concentrated brine from their nostrils.<p>The fulmar prion has two subspecies:

Great Skua
Stercorarius skua
Powerful dark brown seabird, resembles a dark, heavily built immature gull. Note eye-catching white flashes in the primaries when in flight. Adults have distinct pale mottling on the upperparts, which serves to separate them from adults of the very similar South Polar Skua. Juveniles are more uniformly colored, with warm-colored and largely unmarked underparts; note bulkier build and more powerful flight than Pomarine Jaeger. Breeds locally on moorland of islands and coasts in northern Europe, where aggressive near nests. Otherwise lives at sea, but may be seen from shore during windy conditions during migration periods. Feeds by pirating gulls and other seabirds, also by scavenging at fishing boats.

Yellow-eyed Starling
Aplonis mystacea
A medium-sized bird of lowland forest in southern New Guinea. All glossy black plumage with a bluish sheen, a longish tail and a mane of loose feathers around the neck. Note the yellow eye. Immature has pale underparts and streaking. Sometimes associates with Metallic Starlings. Similar to Singing and Metallic Starlings, but Yellow-eyed, has an obvious yellow eye. Singing also has a shorter tail and is usually found in towns or open areas. Song, similar to that of Metallic Starling. Call, a short raspy flight note.

Yellow-browed Antbird
Hypocnemis hypoxantha
Rather small antbird with a disjunct distribution. Males have a yellow face and underparts with a black crown, eye-line, and streaks on the breast. Females have a yellow streaked crown. Southeastern subspecies has ochraceous lower underparts. Song is a descending and decelerating series of fluted notes becoming harsher at the end. Found in the understory of humid forests, often in areas of transitional forest or poor soils. Rarely accompanies mixed-species flocks. The similar Spix's and Peruvian Warbling-Antbirds have white breasts, and the song of Peruvian is somewhat slower-paced.
