棕眉山岩鷚 Prunella montanella

The most migratory of the accentors, moving from its breeding territories in Russia to its wintering grounds in northern China and the upper Korean peninsula; vagrates outside this range somewhat frequently. Face is brightly marked: black with a yellow brow and throat. The more faded-looking juvenile can resemble Brown Accentor, but juvenile Siberian has a buffy brow, a gray nape, and buffy underparts. Forages in shrubby areas and thickets, usually in open forests and forest edges. Often seen in dense foliage overhanging or bordering narrow waterways. Song is a rich up-and-down series. Call is a high, thin “seeseeseesee.”
