Streifenammer Oriturus superciliosus

Big, fat, rather social and conspicuous sparrow. Endemic in highlands of Mexico. Occurs mainly in dry bunch grass within open pine woods. Feeds mainly on the ground but perches readily on rocks and in pine trees. Usually in groups that sometimes mix with other sparrows. Note the bold white eyebrow, rusty-brown cap, dark mask, and plain pale gray underparts. No similar species in its limited range.
