Smoky Warbler

Smoky Warbler Phylloscopus fuligiventer fuligiventer is in Shigatse Prefecture, Tibet; tibetanus in southeast Tibet; and weigoldi in eastern Qinghai, eastern Tibet, and northwest Sichuan. Non-breeding mainly at lower altitudes in northeast Indian Subcontinent. HABITAT Breeds in dense scrub above timberline, between 3000-5000 m (9,840-16,400 ft.). ID & COMPARISON High-altitude and western Chinese counterpart of Dusky Warbler P. fuscatus. Like Dusky, drab-brown, slender, lacking wingbars and with thin bill and distinct buffish-white supercilium. Smoky has darker, sooty-brown upperparts, mainly dusky-olive underparts, shorter and less distinct supercilium behind eye, shorter tail, and darker lower mandible and legs. Race weigoldi much paler below and similar to Dusky; fuligiventer has obvious yellowish tinge to underparts. Sulphur-bellied Warbler P. griseolus and Tickell’s Leaf Warbler P. affinis are paler and more yellow below and on supercilium. VOICE Call a more rolling chrek than Dusky. Song a single note, tsli, repeated up to 10 times, slower, simpler, and less melodious than Dusky. — Craig Brelsford
