Tibetan Sandgrouse

Syrrhaptes tibetanus

A sandy-colored ground bird with a thin needle-point tail and a gentle, dove-like profile. Not as well-marked as other sandgrouse: soft sandy brown with a light orange face and finely barred breast. Female has weak barring all over her back and wings. Often seen in flight, during which it reveals extensive black on the underwings and the upper end of the upperwings. Does not regularly visit water holes, unlike many other sandgrouse species. Inhabits wide, open expanses of semi-desert.

识别特征

The Tibetan sandgrouse is about 30–41 cm long, with a small, pigeon-like head and neck, but sturdy compact body. It has long pointed wings and pin tail. It has an orange face, finely barred grey breast, neck and crown, white belly and black underwings. Male has unspotted buff wing while the female has barred wing coverts, upperparts and upper belly than the male. Juvenile lacks the tail pin, has narrower barrings and has less orange on the face. White belly and dark underwings are distinctions from the related Pallas's sandgrouse, with which its range overlaps. As with that species, its small feet lack a hind toe, and the three front toes are fused together. The upper surface is feathered, and the underneath has a fleshy pad. The appearance of the foot is more like a paw than an avian foot.

分类信息

Currently considered monotypic. Birds from the Pamirs were earlier separated as race pamirensis. The species was first described by Gould in 1850 based on specimen from Tso-Morriri in Ladakh.

Arrowhead Piculet

Arrowhead Piculet

Picumnus minutissimus

Common piculet of coastal forests. Note short-tailed profile, large feet, and cone-shaped bill. Found in mangroves, gardens, abandoned plantations, and disturbed areas. Creeps quietly through vine tangles and bores into dead twigs at lower and middle levels. Similar to Golden-spangled and White-barred Piculets, but Arrowhead has chevron-shaped spots (not barring) on the breast and belly, and is strictly confined to coastal habitats.

Ochre-breasted Antpitta

Ochre-breasted Antpitta

Grallaricula flavirostris

Small and fairly bright antpitta found in foothills and subtropics from Costa Rica to Bolivia. Typical antpitta shape: plump and short-tailed. Dull brown above. Messy-looking buffy face and eyering. Some geographic variation: breast color varies from buffy to whitish, and some populations show bold dark scaling on breast, while others are nearly unmarked. Sexes similar. Shy and difficult to see; stays on or near the ground in forest, often perching on small limbs a couple meters high (more so than the larger antpittas). Swings its body side to side. Song can be difficult to detect: a simple, extremely high pitched, descending whistle. Occurs from around 500–2,500 m, usually lower than other small antpittas.

New Britain Boobook

New Britain Boobook

Ninox odiosa

A small brown owl confined to New Britain with a dark brown head, prominent white eyebrows and throat patch, and orange-yellow eyes. Broad brown chest band contrasts with pale mottled whitish underparts. Upperparts and wings dark chocolate brown with scattered white markings. Occurs in forest and in modified patches and clearings, in the lowlands and foothills. Distinctive: the only small brown owl on New Britain. Song is a distinctive, incessant series of “whoo” notes, rising in volume toward the end.
