识别特征
Adult rufous-breasted wrens of the nominate subspecies are 14 cm (5.5 in) long and weigh 13.5 to 18.5 g (0.48 to 0.65 oz). Their crowns and upperparts are warm brown; their tail is gray-brown with heavy dark brown bars. They have a white supercilium with a black edge above it. Their face and throat are speckled black and white. The chest is bright chestnut. The rest of the underparts a duller chestnut with a grayish white center to the belly. Juveniles are duller than the adults and the facial markings are less distinct. The facial pattern and rufous breast are unique in the genus.<p>P. r. hyperythrus is similar to the nominate with the addition of blackish spots on the chest. P. r. laetus also has blackish spots but its underparts are colored richer than those of hyperythrus. P. r. hypospodius compared to the nominate is more reddish on the crown and back and its chest is more tawny and the flanks duller. P. r. interior's underparts are pale ochre and its flanks pale olive brown. P. r. intensus is more richly colored than the nominate and often has some spotting. P. r. tobagensis' bill is heavier than the nominate's; it also has longer wings and a duller chest.
分类信息
The rufous-breasted wren was formerly placed in the genus Thryothorus which in the old, broad sense was a motley assemblage of similar-looking wrens. Since being moved into genus Pheugopedius it has at times been treated as conspecific with speckle-breasted wren (P. sclateri) and spot-breasted wren (P. maculipectus). They do form a superspecies.<p>The rufous-breasted wren has seven subspecies:

Nepal House-Martin
Delichon nipalense
A typical house-martin, with dark upperparts, white underparts, a white rump, and a rather dumpy body. Differs from Common and Asian House-Martins by its sooty throat. Upperparts can have a bluish gloss if seen in good light. Breeds on ridges and cliffs, and occasionally around human settlements. Associates with other swallows and swifts, often gathering over water to catch emerging insects.
Abbott's Booby
Papasula abbotti
Gangly, stretched-out-looking black-and-white seabird. Strikingly slender and strange-looking in flight. Breeds in the rainforest canopy of Christmas Island, and forages in the adjacent ocean. Some birds, especially immatures, will forage much farther afield, but the extent of these rangings is still poorly understood. Bizarre long-necked and slender-winged profile is unique, and should readily distinguish this species from any others in range. Bill is pale pink in females and grayish in males.
Chestnut-rumped Thornbill
Acanthiza uropygialis
Small bird with thin pointed bill, found in woodland and shrubland across much of arid inland temperate Australia. Brownish gray above, cream-colored below, with white eye, pale speckling on forecrown, pale-tipped dark tail, and vivid chestnut rump, often visible in flight. Forages in small flocks in understory bushes and also on the ground. Young bird has dark eye and can be confused with Slaty-backed Thornbill. Compare Inland Thornbill, which has a heavily streaked chest. Typical calls are very thin rapid chatter interspersed with slower, high- pitched "seeeep seeeep."
