However, the Clements taxonomy and BirdLife International's Handbook of the Birds of the World include A. m. fumosus within A. m. maritimus. This article follows the six-subspecies model. The black-billed shrike-tyrant is 22 to 24 cm (8.7 to 9.4 in) long. The sexes have the same plumage. Adults of the nominate subspecies A. m. montanus have a whitish stripe above the lores, a buffish white... Wikipedia →
