About These Birds
Baird's Sparrow
The Baird's Sparrow is a small sparrow that breeds on the northern Great Plains of North America and winters in the southwestern United States and Mexico, weighing about 17.9g with a wingspan of 13.1cm. It inhabits native grasslands and feeds on seeds and insects. Grassland loss on both breeding and wintering grounds has reduced its populations.
