Grey-hooded Warbler

Grey-hooded Warbler Phylloscopus xanthoschistos is a Himalayan species, present in southern Tibet, with jerdoni in Shigatse Prefecture and flavogularis in Nyingchi Prefecture and both subspecies presumably present in Shannan Prefecture. HABITAT & BEHAVIOR Broadleaf and mixed broadleaf-conifer montane forests, secondary as well as primary, from 950-2750 m (3,120-9,020 ft.). Forages restlessly, constantly flashing tail and flicking wings. Mainly in mid-canopy, less often in high canopy and low bushes; rarely descends to ground. Sometimes hovers like sunbird. ID & COMPARISON Conspicuous yellow, grey, and green warbler, with blackish-grey eye-stripe, indistinct and broken white eye-ring, greyish-white supercilium, and faint pale-grey coronal stripe. Grey hood (to mantle and back) contrasts with bright yellowish-green rest of upperparts (including wings) and lemon-yellow underparts; brownish-grey tail with yellowish-green fringing, outer tail feathers largely white (tail may appear white from below). Juvenile duller. Feet orange-brown or pinkish-grey; bill blackish above, yellow-orange below. Race flavogularis is darker than jerdoni and has olive wash to flanks. Quite similar golden-spectacled warblers have yellow eye-ring and black lateral crown stripes but lack dark eye-stripe and whitish supercilium. Yellow-bellied Warbler Abroscopus superciliaris has olive-green nape, mantle, and back, greyish-white throat, and stronger and darker bill and lacks coronal stripe and extensive white on outer tail. VOICE Song, often introduced by psit call notes, a brief, high-pitched warble, constantly repeated, with short pauses in between. Common call a three-syllable psit-su-it, with middle note lower-pitched. — Craig Brelsford
