Phylloscopus proregulus kansuensis
vicinity of Lauhukou, north Gansu Province, China.
Formerly treated as a junior synonym of P. proregulus or of P. chloronotus (which has similarly been lumped within that species). Various studies, however, have indicated that it is distinct vocally, genetically and in habitat choice; in playback experiments, present species and P. forresti responded little or not at all to each other’s songs. Monotypic.
C China (NE Qinghai, SW Gansu); non-breeding range unknown.
