Calls of the Jungle Crow (Corvus macrorhynchos s. l.) as a taxonomic characterResults of the Himalaya Expeditions of J. Martens, No. 224. - For No. 2…

Summary A discriminant analysis of the call structure completely separates three Corvus taxa (levaillantii and japonensis of the ‘macrorhynchos group’, splendens) inhabiting the southern slopes of the Himalayas (Nepal, Kashmir). The acoustic differences are considered taxonomically relevant, indicating species boundaries. Therefore the Jungle Crows of lower and upper Nepal (contact zone at around 2,000 m) are assigned to two biospecies (C. japonensis and C. levaillantii), as is consistent with morphological, ecological and parasitological data. It appears possible to extrapolate the findings regarding call structure to the systematics of other ‘macrorhynchos’ populations as distant as the R…
