A less common bird than the Red-eye, but like it generally distributed
through woodland, garden and orchard. It's song resembles the Red-eye's
in form but is richer in tone, more deliberately uttered, and not
continuous. "See me--I'm here--where are you?" he seems to say, and
after a pause repeats the query.

The nest has the deep cup-shape of our other Vireo's but is externally
covered with lichens. The eggs, laid the latter part of May, are white
with a few specks of black or brown.

We know this Vireo chiefly as a migrant, one of the earliest of the
group of small arboreal wood-haunting birds (Vireos and Warblers) to
reach us in the spring. Its song, as well as its movements, are
deliberate. Vireo-like it peers beneath the leaves or inspects the
blossoms, removing a caterpillar here or an insect's egg there, the
while singing leisurely a rich-toned rendering of the Red-eye's theme.

It nests late in May, hanging its cup-shaped basket to a crotch usually
five to ten feet above the ground. The eggs are white with a few black
or brown
