Chinese Leaf-warbler (Phylloscopus yunnanensis)


Taxonomy

Taxonomy:

Phylloscopus proregulus yunnanensis

Soon after initially described, this taxon was synonymized with P. chloronotus (at the time treated as a race of P. proregulus); but significant differences in morphology, vocalizations, habitat choice and breeding biology now well known, as are sympatric breeding distributions and lack of response to playback of each other’s songs. Present form subsequently described as a new species, P. sichuanensis#R, which was later realized to be a junior synonym of yunnanensis. Monotypic.

Distribution:

C & NE China (E Qinghai, S Gansu, Shaanxi, Shanxi and Hebei S to Sichuan); non-breeding apparently SE Asia.

Food and feeding

Known to eat insects, but no studies undertaken. Forages both in canopy and in understorey; techniques include hovering and short flights.

Breeding

Poorly known. Territorial from mid-Apr, more commonly from early/mid-May, and eggs found in second half Jun. Nest spherical, with side... read more

Status and conservation

Not globally threatened. Locally abundant in breeding area. In non-breeding season, locally rather common in Thailand. No population estimates.
