Green Catbird
Ailuroedus crassirostris
Chunky rainforest bird with emerald green upperparts, dark eye, and green-olive underparts with pale streaking. Inhabits the east coast of Australia from southeastern Queensland to the south coast of New South Wales, thus does not overlap with Spotted Catbird. Forages mostly in middle and upper story of the rainforest. Compare female and juvenile Satin Bowerbird (with blue eye, darker bill). Call a very loud yowl, which sounds just like a cat.
识别特征
Green catbirds are a medium-sized stocky bird with long, powerful legs and a long, stout bill. The back, wings and rump are brilliant emerald green, with very conspicuous pure white spots at the tips of the tertiaries and secondaries, which, on the tips of coverts, form two white wing-bars. The tail is brownish emerald with white tips. The head is greenish brown mottled black and finely flecked pale buff. The chest is greenish buff to dull emerald with distinctive short white streaks.<p>The bill is horn coloured and the legs are greyish brown.<p>The iris is bright red in direct sun with a partial white eye-ring.<p>Male and female birds share similar plumage, making it very difficult to distinguish between the sexes. Juvenile birds also have similar plumage, although it is duller. Very young birds have fluffy grey down on their heads (Donaghey. R. 1996).

分布与栖息地
According to The Field Guide to Australian Birds (Michael Morcombe, 2003) (2nd edition), green catbirds are found along the length of the east coast of NSW (in areas of suitable habitat) through to the Cooloola Coast in South East Queensland.<p>The birds are found in subtropical and temperate rainforest and paperbarks, and occasionally in adjacent eucalypt forest.<p>The average home range of the birds is five acres, although this is greatly reduced during breeding season. Breeding territories usually contain several fig trees which regularly produce large amounts of ripe fruit for several months which coincides with the catbird breeding season. Green catbirds drink and bath in pools of water that are found in the crevices of surrounding trees or water courses.

保护状况
Although the green catbird is listed as Least Concern on IUCN Red List of Threatened Species, it is listed as Vulnerable in NSW, which is the majority of its range.<p>Although it is widespread and common in its favoured habitat, ongoing clearing of rainforest and paperbark swamps for development is likely to continue to threaten the green catbird in the future.

Rufous-vented Tapaculo
Scytalopus femoralis
A fairly common cloud forest tapaculo found in the eastern Andes of northern and central Peru. Adult is gray with brown bars on the lower underparts. Young birds are browner and extensively marked with buff bars and scales. Similar to Trilling Tapaculo and Junin Tapaculo, and identification should be based on range and voice. Rufous-vented Tapaculo gives sharp chips and low frog-like notes, either alone or in an accelerating series. Inhabits forest understory and usually tough to see.
Buff-fronted Quail-Dove
Zentrygon costaricensis
Plump ground-dwelling dove, quite bright and colorful compared with other quail-doves. Body is grayish, wings are rich brownish-purple, and nape is suffused with iridescent green. Like many quail-doves, face is whiter with dark mustache line, but note buffy forehead. Pinkish-red legs. Sexes alike. Prefers forests, usually on the ground unless flushed up into the lower levels of a tree. Like most quail-doves, often best seen by quietly walking along trails at dawn and dusk.
Yellow-throated Bulbul
Pycnonotus xantholaemus
Plain, pale brownish bulbul. Endemic to very specialized habitat in South India. Only found in hills with dry rocky scrub and boulders, co-occurring locally with the more widespread White-browed Bulbul throughout its range. Although both species have a yellow vent and can sound similar, Yellow-throated can be distinguished by its yellow head that contrasts with its whitish underparts. Usually occurring in pairs, it tends to rove along regular circuits, often perching on exposed rocks and boulders. Voice like White-browed’s, but more melodious and higher in pitch.
