Orange Weaver
Ploceus aurantius
A medium-sized weaver with a long, relatively slim bill. Male is mostly bright yellow with an orange throat and black lores. The female is much duller, greenish-yellow with a white belly. The eye color of both sexes can be whitish or red, and the bill can be mostly pinkish or black. A colonial nester that is found around wetlands, including lakes, rivers, and swamps. Similar to Holub’s Golden-Weaver, but smaller and slimmer-billed. Female can be confused with several other female and non-breeding male weavers, but is usually found in association with the more distinctive males. Vocalizations are typical of weavers: “chet” notes and a sizzling “radio static” song.
识别特征
The orange weaver can reach a length of about 12.5 centimetres (4.9 in), including the tail. These birds exhibit sexual dimorphism, and plumage also varies seasonally. During breeding or "nuptial" season, the male has a black beak, a small patch of black skin in front and behind the eyes (making the eyes look oval in shape), and brown wings. The rest of the plumage is a brilliant red to orange in color. Bill is pale and slender, while eyes are reddish-brown or pale grey.<p>Outside of breeding season, the males sport plumage that is considerably more drab, brown overall with some dark streaks and a cream-colored belly. The females have the same plumage year-round, which resembles that of the off-season males. The males of this species are often confused with males of the species Euplectes orix, commonly known as the southern red bishop. This bird has a black belly, however.

行为
In the wild orange weavers are polygamous, two or three females should generally be provided for each male and they make their homes in reed beds close to the surface of water. Like most other finches, these birds are colonial, with hundreds of complexly woven nests at some sites, which include palms, reeds and other trees.<p>They mainly feed on fruit and seeds, but also on insects (locusts, beetles, caterpillars). They are usually found in pairs or in small groups. Males build an ovoid nest with grass and palm strips. Females lay two eggs and incubate them.

Silvereye
Zosterops lateralis
Tiny bird with an obvious pale eyering. Subspecies vary in plumage; most have a green head, green lores (area between bill and eye), yellowish throat, gray (or green) back, pale gray underparts, and green wings and tail. The migratory Tasmanian subspecies has brownish flanks. Rather common, seen in small flocks that feed in bushes and shrubs in the mid-story. The only species of white-eye over much of its range.
Gold-naped Finch
Pyrrhoplectes epauletta
A small dark finch of high mountain forests. Male is glossy black with a bright yellow nape. Female is brown overall with a pale yellow suffusion to the back of the head and black wing tips. Usually forages in small to medium-sized flocks; often associating with other species in mixed-feeding flocks.
Small Tree-Finch
Camarhynchus parvulus
A small Galápagos finch with a dainty bill. Bill is slightly curved on both upper and lower edges, and longer than it is deep. Male has a black hood, gray-brown upperparts, and a pale belly. Female is tan with whitish to buffy underparts. Both sexes have a variable amount of streaking on the breast. Bill is black on breeding male and orange on female and non-breeding male. Bill is smaller and less curved compared to other tree-finches. Female is similar to female Small Ground-Finch, but on that species the lower edge of bill is straight--not curved. Found on most of the larger islands, but absent from Española, Genovesa, and Marchena. Inhabits a wide range of habitats and elevations.
