627. Vireosylvia gilva. 5 inches.

Above olive-green; crown grayer but with no black border. These are among the most common of the Vireos and may be found even in the hearts of large cities, swinging their pretty little nests high up in shade trees. Their song is after the style of that of the Purple Finch, very different from that of the Red-eye. The eggs are white with a few brown specks on the large end. These birds breed throughout the U. S. and southern Canada.
