Western Savannah Sparrow
542b. Passerculus s. alaudinus. 5½ inches.
This is a slightly paler form of the preceding, and is very common in the fields and meadows, from northern Alaska to Mexico. They are birds but very little seen, keeping in the grass the greater part of the time. Their nests are hollows in the ground lined with fine grass and concealed by tufts of grass. They usually deposit four eggs, grayish white, blotched heavily with brown (.75 ×.55).
