Erckel's Spurfowl
Pternistis erckelii
A pheasant-sized game bird with a chestnut crown, white throat, and white streaks above and below. Males are larger than females. Occurs in grasslands, shrubby areas, and gullies, usually in uplands. Prefers wetter areas than Gray and Black Francolins. Call is a loud series of laughing “er-er-er” notes descending in pitch toward the end. Introduced to Hawaii where it is common on Kauai, Lanai, and Hawaii and local on Oahu and Maui.
识别特征
The largest African spurfowl, Erckel's spurfowl is 38–43 cm (15–17 in) in length, with females being slightly smaller than males. Males grow to 1.05–1.59 kg (2.3–3.5 lb), based on a sample of three specimens, and a single female specimen was observed to weigh 1.136 kg (2.50 lb). Males and females have similar plumage. The body is covered with stripes of chestnut-color, on its upperside and underside. It has a black face and bill, a chestnut-colored head top and back of neck, and yellow legs. It has white ear coverts and a single streak of white behind its eye.
分类信息
Erckel's spurfowl was described in 1935 by the German naturalist Eduard Rüppell from specimens collected in the mountains of Ethiopia. He coined the binomial name Perdix erckelii. The specific epithet was chosen by Rüppell to honour his assistant, Theodor Erckel (1811–1897), who had helped with the collection of specimens. The species is now placed in the genus Pternistis that was introduced by the German naturalist Johann Georg Wagler in 1832. Erckel's spurfowl is monotypic: no subspecies are recognised. A phylogenetic study published in 2019 found that Erckel's spurfowl was most closely related to the Djibouti spurfowl.

分布与栖息地
Erckel's spurfowl is native to the northern parts of Eritrea and Ethiopia, as well as northeast Sudan. In 1957, the species was introduced to Hawaii as a gamebird; it has also been introduced to Italy. It lives in areas 2,000 to 3,500 metres (6,600 to 11,500 ft) above sea level, such as in the mountainous Degua Tembien district. Although its exact population is unknown, it is a common species with an estimated range of 580,000 km2 (220,000 sq mi), causing it to be listed as a species of least concern by the International Union for Conservation of Nature.

行为
Erckel's spurfowl can hunt alone or in pairs, in scrublands or at the edge of forests. Its diet consists of plants, such as berries, seeds, and shoots, as well as insects. It is frequently inactive, but if threatened it runs up a hill. It produces territorial calls, which consist of 15–20 notes and are made from clifftops and large rocks. The species' vocalizations are frequently repeated over a long period, and have been described as "an insane cackled laughter, speeding towards the end with a bouncing ball pattern". Eggs are laid during the rainy season from April to November, with the exact time depending on the location; they are laid in May and September to November in Ethiopia, while they are laid in April and May in Sudan.

Black Oystercatcher
Haematopus bachmani
Large, bulky shorebird. Dark overall with thick red bill, staring yellow eye, and thick, light pink legs. Exclusively coastal, favors rocky shorelines where it feeds on shellfish and other invertebrates. Usually in pairs or small flocks. Occurs from Alaska to northern Baja. Listen for loud yelps and whistles, often in a rapid series when excited. Hybrids with American Oystercatcher occur locally in southern California and Baja; look for messy spotting on the belly.
Western Capercaillie
Tetrao urogallus
Huge gamebird of conifer forest, adjacent moorland, and clearings with shrubs, mainly in wilder areas. Mostly elusive, but occasional males go "rogue" and attack hikers. Groups of males display just after dawn in early spring, holding their tail raised and fanned like a turkey. Massive male is blackish overall with long tail, white shoulder spot. Female appreciably smaller than male, told from smaller female Black Grouse by unbarred rusty breast and bright rusty tail with black bars.
Red-crested Cotinga
Ampelion rubrocristatus
This plump gray bird is a regular sight atop patches of trees from the temperate forest zone to above treeline in the Andes from Venezuela to Bolivia. The plumage is unremarkable at first glance: both sexes are medium gray with a darker face, blackish wings, and a white band on the tail (visible in flight). The namesake red crest is usually laid flat down the nape, but is occasionally raised into a spectacular splayed bouquet of feathers. Singles or pairs are usually seen perched conspicuously. Found in forested areas, but does not require high-quality intact forest, and can be found in surprisingly small patches of bushes and trees in agricultural areas.
