分类信息
The silvery-cheeked antshrike was originally described as Turdus cristatus. and was later transferred to genus Sakesphorus. Its transfer to the new genus Sakesphoroides was proposed in 2010 based on the species' distinctive morphology. It uniqueness was confirmed by a genetic study published in 2010. Based on that study, the South American Classification Committee of the American Ornithological Society, the International Ornithological Congress, and the Clements taxonomy quickly moved the silvery-cheeked antshrike to Sakesphoroides. However, as of December 2023 BirdLife International's Handbook of the Birds of the World retained it in Sakesphorus.<p>The silvery-cheeked antshrike is the only member of genus Sakesphoroides and has no subspecies.

分布与栖息地
The silvery-cheeked antshrike is found in northeastern Brazil from Ceará and central and western Rio Grande do Norte south through southeastern Piauí, western Pernambuco, and inland Bahia into central Minas Gerais. It inhabits the understorey to mid-storey of deciduous forest and arid caatinga, and also the ecotone between deciduous and ridgetop evergreen forest. It favors areas where the forest has a closed canopy, such as mata-de-cipó. In elevation it ranges from sea level to 1,100 m (3,600 ft).

Dinelli's Doradito
Pseudocolopteryx dinelliana
Small yellowish flycatcher of marshlands in central and northern Argentina, moving north during the nonbreeding season. Similar to Subtropical, Warbling, and Ticking Doraditos, from which it is most easily identified by voice, but note brownish cap and brownish (as opposed to olive or gray) auriculars.
Pine Warbler
Setophaga pinus
A medium-sized, rather robust and long-tailed warbler, with a noticeably stout bill. Variable plumage, from bright adult males with extensive yellow throat to extremely dull grayish-brown immature females. Always look for two white wingbars, diffuse streaking on the sides of the breast, large bill, and long narrow tail with a shallow notch. Well-named: almost always found in pine trees throughout the year. In spring and summer, listen for loud musical trill (compare with Chipping Sparrow and Dark-eyed Junco). Occasionally visits feeders, especially for suet. A short-distance migrant, wintering entirely in the United States.
Buff-banded Mountain Tanager
Dubusia taeniata
A relatively small and inconspicuous mountain-tanager found in the upper subtropical and temperate zones of the Andes. Blue above with a yellow belly and black head. Buffy breast band is not super conspicuous. Look for unique spangled blue eyebrow. Sexes alike. Found alone or in pairs, typically moving quietly through the understory of forest and edge. Often follows mixed-species flocks.
