Red-eyed vireo.

Slower at the pond today, seven species of warblers and a red-eyed vireo., among others.

Vireo olivaceus.
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.
