627. Vireosylva 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.
YELLOW-THROATED VIREO
628. Lanivireo flavifrons. 5¾ inches
Upper parts greenish; throat, breast and line over eye yellow; two prominent whitish wing bars.
A handsome Vireo found in localities such as are frequented by the Red-eyed species. Nowhere do they appear to be as abundant as that species, however; they are more abundant than many suppose, but the difficulty of clearly seeing the yellow breast when they are feeding in the tree tops, combined with the similarity of their songs, usually caused them to be passed by without inspection.
Song.—Similar to that of the [Red-eye], but louder and more nasal, less varied and not uttered as often.
Nest.—A pensile structure of strips of bark, grasses, etc., with the outside often ornamented with lichens; three to five eggs with a creamy or rosy-white tint, specked, more profusely than those of the [Red-eye], with reddish brown (.82 × .60).
Range.—Eastern U. S., breeding from the Gulf to southern Canada; winters in Central America.
