Mouse-colored Penduline-Tit

Dull brown fulvetta with pale eyes, found only in central and south-central China. Note streaky throat, dark lores, and pale, narrow wing panel. Distinctive in its blandness; no other fulvetta in the region is essentially all brown with no dark eyebrows or significant patches of warmer, brighter colors. Occurs at 2200-4300 meters, favoring areas with shrubby oak or rhododendron cover. Typically forages low down or at middle levels of forest. Not as social as the “Alcippe” fulvettas, and are often encountered singly or in pairs, though small groups do occur. Song is a simple but variable series of whistles in which the first note or two rise and the last one or two fall, sometimes with an intermediary note in between: “tsi-tsi-dih-deer-deer.” Call is a high-pitched chittery rattle.

Fairly dull vireo, intermediate between Blue-headed and Plumbeous. Grayish-olive overall, but with yellowish flanks and greenish back. Note white spectacles contrasting with gray head and two whitish wingbars. Breeds in mixed coniferous forests, especially in mountainous areas; winters in Mexico. Often separable from Blue-headed and Plumbeous Vireos by range, but can overlap during migration and winter. Cassin's is less contrasty than Blue-headed, especially between the gray face and whitish throat, and the greenish back blends into the nape and crown. Some birds are best left unidentified.

Distinctive small tyrannulet with rufous brow, black mask, olive back, and yellow underparts. Looks like a more colorful version of Rufous-browed Tyrannulet. Sexes similar. Found alone or in pairs, often in mixed-species flocks, in the canopy of forest. Occurs in humid forest and forest edges of montane regions. The typical voice has four high notes “teeup teeup teeup teeup.” No similar species in range. Endemic to the Coastal Cordillera of Venezuela.
