This vireo nests in our area and we hear their calls all summer long.
Here I am, where are you. Over and over and over....

Vireo olivaceus

Song a broken series of slurred notes. Each phrase usually ends in either a downslur or an upswing, as if the bird asks a question, then answers it, over and over.

The red iris that gives the Red-eyed Vireo its name doesn't develop until the end of the birds' first winter. Then the brown iris the birds were born with becomes dull brick red to bright crimson in different individuals.

The oldest known Red-eyed Vireo was banded in its hatching year and then refound, and rereleased, when 10 years and 2 months old.
