Reguloides humei

W. E. Brooks

, 1878,

North-West Frontier Province, India


Formerly considered conspecific with P. inornatus, but differs clearly in vocalizations and plumage, and co-exists sympatrically#R; some evidence that the two may occasionally hybridize#R. Race mandellii sometimes treated as a separate species; differs genetically#R and in its generally duller, browner plumage above and dingier plumage below (not always perceptible; hence no score); song type 1 drops more in pitch initially (2) and has a wider frequency range (1), while song type 2 has subtly different note shape (ns[1])#R; moreover, calls are clearly different. Two subspecies recognized.
