Range. - North America, east of the Plains, and from New Brunswick and Manitoba southward; winters from the Gulf States southward.
This trim and graceful, but quarrelsome, species is grayish on the head, neck, and breast, shading to greenish on the back and quite abruptly into bright yellow on the underparts; the head is slightly crested and the inner webs of all the lateral tail feathers are reddish brown. They are abundant in most of their range but are generally shy so they are not as often seen as many other more rare birds. They nest in cavities of any kind of trees and at any elevation from the ground, the nest being made of twigs, weeds and trash, and generally having incorporated into its make-up a piece of cast off snake skin. They lay from four to six eggs of a buffy color, blotched and lined with dark brown and lavender. Size .85 x .65.
