Golden Dove
Ptilinopus luteovirens
A spectacular and unique dove. Male is vivid golden yellow with peculiar hair-like feathers, a thin but bright yellow collar, and green bare skin around the eye. Female is mostly green with a yellow undertail, a brownish face, and green feet. She resembles female Orange and Velvet Doves, but those species do not overlap in range. Voice most resembles a heron-like croak or distant dog bark, given every few seconds.
识别特征
The golden dove (Ptilinopus luteovirens), also known as the golden fruit dove, lemon dove or yellow dove, is a small, approximately 20 cm (8 in) long, short-tailed fruit-dove in the family Columbidae. The common name refers to the males' bright golden-yellow colour. The body feathers appear almost iridescent due to their elongated shape and hair-like texture. The head is slightly duller with a greenish tinge. The bill, orbital skin and legs are bluish-green and the iris is whitish. The underwings and tail coverts are yellow. The female is a dark green bird with bare parts resembling those of the male. The young resembles the female. The golden dove is endemic to the forests of Fiji. The diet consists mainly of various small fruits, berries and insects. The female usually lays a single white egg. The golden dove is closely related to the whistling dove and orange dove. These species are allopatric, meaning they do not share the same habitat in any location. A common species throughout its limited range, the golden dove is evaluated as Least Concern on the IUCN Red List of Threatened Species.
分类信息
The golden fruit dove is one of over 50 species in the genus Ptilinopus. Within the genus, it is most closely related to the orange fruit dove and whistling fruit dove. These three species are placed together in their own subgenus, Chrysoena. They are also sometimes treated as their own genus. It is monotypic.<p>The species' generic name comes from the Ancient Greek ptilon (feather) and pous (foot), while the specific epithet luteovirens is from the Latin luteus (orange-yellow), and virens (green), referring to its colour.

Grauer's Broadbill
Pseudocalyptomena graueri
A unique dumpy green flycatcher-like broadbill with a buffy crown, a black eye-stripe, and a powder-blue throat and vent. Juvenile duller. A scarce resident found singly and in pairs in the lower canopy and at middle levels of primary Albertine Rift Forest between 1760 and 2500 meters of elevation, preferring the edges of clearings. Highly localized, occurring in two isolated populations in Bwindi (Uganda) and Itombwe/Kahuzi (Democratic Republic of Congo), and inexplicably absent from ideal intervening habitat. May join flocks, but inconspicuous unless calling its soft high-pitched tinny “tsit-tsit,” repeated multiple times, and a rapid “tseet-tsit-tsit-sit-sit-it-it” in flight.
Crimson Chat
Epthianura tricolor
Brightly colored, terrestrial songbird of arid inland Australia. Breeding male has crimson crown and belly, gray back, black mask, white throat, pale eye, and blackish wings with narrow pale wingbars. Nonbreeding male more muted, with only hints of crimson. Female similar to nonbreeding male but paler around the face. Usually seen in small groups hopping along the ground in open areas.
Parasitic Jaeger
Stercorarius parasiticus
Slender gull-like seabird; the middle-sized of the three jaegers. Breeds on Arctic tundra; spends the rest of the year at sea. Difficult to separate from other jaegers. Breeding adults have a long pointed tail (not as long as Long-tailed Jaeger). Plumage varies from entirely dark blackish-brown to paler with white belly and yellowish on the side of the neck. Immature birds are variable but usually warm brown with cinnamon barring on wings. Barring on underwing and undertail is weaker than on Pomarine Jaeger. Shape and flight style are intermediate between Pomarine and Long-tailed. Typically shows white shafts on four to six outermost wing feathers, more than Long-tailed, but less than Pomarine. Bill is relatively long and slender. All jaegers chase other birds and steal their food.
