Lemon-rumped Warbler

Lemon-rumped Warbler Phylloscopus chloronotus simlaensis ranges across western Himalayas to central Shigatse Prefecture, Tibet, and P. c. chloronotus from central Shigatse Prefecture eastward. Range of chloronotus abuts Sichuan Leaf Warbler P. forresti in eastern Tibet. HABITAT Breeds mainly in forests in which conifers predominate, also oak forests, between 1800-4200 m (5,910-13,780 ft.). ID & COMPARISON Member of Pallas’s Leaf Warbler Complex; very similar to Gansu Leaf Warbler P. kansuensis and Sichuan Leaf Warbler. Race simlaensis on average brighter and more strongly marked than nominate, which in turn is paler than Sichuan Leaf Warbler. Pallas’s Leaf Warbler P. proregulus has bright lemon-yellow supercilium (anteriorly) that is usually broadest in front of eye, darker sides of crown, and blackish eye-stripe (i.e., bolder head pattern), and on average greener mantle, yellower wingbars, and whiter underparts. VOICE One song type is trill or rattle consisting of two parts and lasting 2 or 4 seconds, first part fast and slightly buzzy, second part slower, more ringing, and on a slightly lower pitch; trills often interspersed by single or double tsi calls. This song can be similar to one song type of Sichuan Leaf Warbler, but Lemon-rumped dryer and faster. Other song is prolonged series of notes and trills. Sharp dweet call shorter than Sichuan Leaf Warbler. Also more ample si-tu call, second note lower-pitched. — Craig Brelsford
