Black-throated Sparrow

Amphispiza bilineata

Black-throated Sparrow
copyright Robert Shantz
Length: 6 in. (14 cm)
In flocks with other sparrow species in the winter or pairs alone in the summer, this desert-dwelling species is common. It lives in some of the most extreme heat and dryness on the continent but seems to thrive. It relies on moisture from the grass and insects it eats and only during the winter drinks water directly from ponds and streams. The male's song varies considerably from place to place. Its grassy nest is in a bush near or on the ground. The four-digit banding code is BTSP.
