Floreana Mockingbird
Mimus trifasciatus
A fairly large gray-and-white songbird with a long tail, curved bill, and black blotches on sides of breast. Endemic to Galápagos. Now found only on two tiny islets (Gardner and Campeón) off the coast of Floreana Island, it is the only species of mockingbird in its range. Tourists are not allowed to land on these islets, so the birds are usually seen from a boat while they are perched up on cacti or small trees.

The Floreana mockingbird is 25 to 26 cm (9.8 to 10.2 in) long. Males weigh an average of 65.7 g (2.32 oz) and females 59.8 g (2.11 oz). Adults have a pied appearance. They have a pale supercilium, a black patch in front of the eye, a darkish one below it, and white cheeks. Their crown, upperparts, and tail are grayish brown with a few faint darker streaks. Their whitish underparts have a dark patch on the side of the breast and faint spots on the breast and flanks. The folded wing shows two white bars. The juvenile is similar to the adult but more heavily streaked.

分布与栖息地
The Floreana mockingbird was formerly abundant on Floreana Island but had been extirpated from there by 1888. It now occurs only on two islets off Floreana's shore, Campeón and Gardner-near-Floreana. The islets provide a habitat of low vegetation along their shores and arid scrub with cacti and a few trees inland.

Orchard Oriole
Icterus spurius
Small, slender oriole. Adult males are a unique rich chestnut-brown color with a black head. Females are dull yellow-green with white wingbars. Immature males are similar to females, but with a black throat and mask. Breeds in open woodlands, river edges, pastures with scattered trees, and brushy orchards. Visits feeders with nectar and fruits. Departs breeding grounds early and heads to wintering grounds in Mexico and Central America, where it can be found in any open or wooded habitat. Compare with female Hooded Oriole, which is larger and longer-tailed and has a narrower, more curved bill.

Wilson's Indigobird
Vidua wilsoni
A nest parasite that lays its eggs in the nests of Bar-breasted Firefinch. Breeding males are glossy purplish-black with a pale brownish panel in the wings, while females and non-breeding males are brown and streaky on the back and pale below, with a bold facial pattern. The bill is white and the legs pinkish. Found in a wide variety of open habitats including open woodland, thickets, savanna, cultivated areas, and scrub. Breeding males can be identified with care by their vocalizations and purple gloss. Non-breeding males and females cannot be separated visually from other indigobirds. Imitates the vocalizations of its host firefinches: a low “chip” call and an up-and-down twittering song.

Narrow-billed Antwren
Formicivora iheringi
Long-tailed antwren with white flanks, unmistakable within its restricted range. Males are dark gray with a black bib. Females are olive-brown above and cinnamon below with two buff wing bars. Found in deciduous forests, where it forages from the understory to middle levels, usually alone but sometimes loosely accompanying mixed-species flocks. Songs a long series of clear “tiuw” notes.
