White-bellied Seedsnipe
Attagis malouinus
Chunky, generally scarce, rather grouselike bird of bleak moorland, bogs, and rocky slopes above timberline; in winter, sometimes descends to lowland Patagonian steppe, when it can be seen along roadsides. Found in pairs or small groups. Lacey “chainmail” pattern to upperparts is beautifully cryptic, and birds sometimes freeze when alarmed making them more difficult to see. No similar species in range; note the short stout bill and contrasting snowy-white belly. Flight strong and fast; flushes with loud shrieking choruses.
Identification
The white-bellied seedsnipe is 26.5 to 29 cm (10 to 11 in) long and weighs about 310 to 400 g (11 to 14 oz). The sexes are essentially alike. Males' upperparts and breast have an intricate scallop pattern of buff, cinnamon, and black; their chin and belly are white. Females have a somewhat less sharp division between the breast and belly than males. Juveniles are very similar to adults but are slightly paler and have somewhat heavier scalloping.
Taxonomy
The white-bellied seedsnipe was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1772, in his Histoire Naturelle des Oiseaux from a specimen collected on the Falkland Islands. The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name, but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Tetrao malouinus in his catalogue of the Planches Enluminées.<p>The white-bellied seedsnipe is now placed in the genus Attagis that was erected by the French ornithologists Isidore Saint-Hilaire and René Lesson in 1831. Attagis was used for a game bird in Ancient Greek texts. It probably referred to the black francolin (Francolinus francolinus).<p>The specific epithet malouinus refers to the Îles Malouines, the French name for the Falkland Islands. The species is monotypic.

Range and habitat
The white-bellied seedsnipe is found from southern Chile's Magallanes Region and west-central Argentina's Río Negro Province south through Tierra del Fuego to islands off Cape Horn. It has also occurred as a vagrant in the Falkland Islands. In the breeding season it inhabits windswept ridges and moorland characterized by crowberry heath (Empetrum rubrum) and cushion plants. It also occurs along creeks and at small wetlands. Outside that season it mainly inhabits the Patagonian steppe.

Behavior
The white-bellied seedsnipe breeds between elevations of 650 and 2,000 m (2,100 and 6,600 ft) and moves to lower elevations in the austral winter. There it typically forms flocks of up to about 50 birds and sometimes more.<p>The white-bellied seedsnipe feeds on crowberry and other plant matter but details of its diet are lacking.<p>Little is known about the white-bellied seedsnipe's breeding biology. It lays eggs at least in December and January. Its nest is a shallow scrape in the ground lined with grass, moss, and lichen, and the clutch size is typically four eggs.<p>The white-bellied seedsnipe's flight calls are "an excited-sounding 'tu-whit tu-whit' or 'too-ee too-ee...', given continually."

Silver Gull
Chroicocephalus novaehollandiae
Small gray gull with red legs. Adult has red bill (younger birds have a darker bill), white head and body, pale gray "silver" wings, which have prominent black and white tips. Abundant across much of New Zealand and coastal Australia, including inland areas around waterways and rivers.
Rusty-throated Parrotbill
Suthora przewalskii
A distinctive mid-sized parrotbill with a highly restricted range; limited to a small part of central China where it inhabits mid- to high-altitude montane scrub and open forests with dense low cover, particularly bamboo stands. Dull brown with a gray head, long black eyebrow, and a dark rusty-red face and throat. Moves in small flocks and vocalizes frequently, giving jumbled high-pitched squeaks and rattly trills.
Black-eared Catbird
Ailuroedus melanotis
Chunky rainforest bird with emerald green upperparts, thick pale beak, and a large black "ear" spot below the dark red eye. Underparts are pale green-olive with extensive pale spotting. Inhabits New Guinea, and northern Cape York (Queensland). Almost identical in appearance to the Spotted Catbird, which is fractionally larger, so in Australia this species is best identified by range (Spotted Catbird found only further south in the Cairns region). Forages mostly in middle and upper story of rainforest. Catbirds are well known for their characteristic and distinctive cat-like yowling calls.
