This blue gray species is 10 inches in length; the feathers on the neck and underparts have narrow dark borders, thus giving the plumage a scaly appearance, from which the birds take their name. They have a small tuft of whitish or buffy feathers on the top of the head. It is especially abundant in the dry arid portions of its range, being found often many miles away from water. Their eggs are laid in a shallow hollow under some small bush or cactus, and number from eight to sixteen; they are creamy white, finely specked with buff or pale brownish. Size 1.25 x .95.
