The star finch is an estrildid finch, between 10 and 12 cm in length, with crimson fore-parts of the head and a scarlet bill. The upper and lower plumage is yellow-green, white spotted on the underparts, the belly more yellow. The upper tail coverts are scarlet, tail feathers are brownish scarlet. The female has less crimson on the head, and generally duller than the male, the immature star finch is olive to brownish with a grey face and head.<p>The broad white spots under its chin and down its flanks give rise to its common name. It has a wingspan of between 49 and 56 mm, a bill length between 11 and 13 mm, and weighs between 10 and 12 grams.

Synonyms for the scientific name Bathilda ruficauda include Poephila ruficauda and Neochmia ruficauda.<p>The species is also referred to as red-faced firetail, red-tailed finch, or ruficauda finch. The common name, red-tailed finch, was first used by Gould (1884) and was in near universal use from Hall (1899) until 1926 when the term star finch appeared in the Royal Australasian Ornithological Union's (RAOU) second Official Checklist with no explanation for the change.<p>Hombron and Jacquinot first encountered these birds when they stopped off in Australia as part the French expedition to Antarctica of 1837–1840, traveling aboard the Astrolabe. While Hombron initially placed the bird in the genus Erythura, he indicated that the short legs of the bird could necessitate a new genus, Neochimia. Gray adopted the name in 1849. Derived from the Greek, neokhmos meaning new it signifies "new bird".<p>Gould's species name, ruficauda, is from the Latin rufus meaning red and cauda meaning tail.<p>Three subspecies have been described:

Red-throated Bee-eater
Merops bulocki
A pretty, medium-sized bee-eater with a red throat and a blue lower belly. Also note the black face mask, green upperparts, and pale orange breast. In flight, shows a cinnamon underwing with a trailing black edge. Found in savanna habitats, especially broadleaf woodland, often near water. Usually in small groups that perch conspicuously. The calls are simple trills, most of which have a wooden quality.
Northern Gannet
Morus bassanus
Large seabird of the Atlantic with long, pointed bill, wings, and tail. Adults bright white with cream-colored head and black wingtips. Takes several years to reach adult plumage; juveniles are all sooty-brown and slowly acquire more white as they mature. Nests in enormous colonies on cliffs in the North Atlantic. Spends most of its life at sea, although often fairly close to land, so they are often visible from shore or on whale watching boats. Dives torpedolike into the ocean for fish. Gathers in large feeding flocks, but sometimes solitary.
Green Figbird
Sphecotheres viridis
Male figbird is a distinctive oriole with a moss-green body and a black head with bright red facial skin. Female is brown, with a heavily streaked lighter underside and dull blue-gray or pinkish facial skin. Juvenile resembles a less boldly marked female. Gregarious; typically found in pairs or small groups within forest, edge, woodland, and mangroves in the lowlands. Occurs in a restricted range in the eastern Lesser Sundas, where it is the only figbird. Song comprises imitations, chattering, and twittering. Also gives harsh “wit,” “burr,” and trill notes: “klerr-wit-wit-wit-wit.”
