Field Marks and
Identifying Characteristics:
Was photographing birds in my sister-in-law's back yard area which borders on the Santa Clara River's edge. This vireo popped up, started taking pictures as it moved from branch to branch hunting for insects. Did not think much of it other than I was having a tough time IDing the bird for Utah primarily due to the undersides being completely yellow. Could tell it was a vireo due to the hooked bill and the eye stripe.

Song or call & method of delivery: No vocalization
Behavior: Hunting for insects.
Habitat: Scrub brush along river's edge; some oak and willow
Similar species and how
were they eliminated:
Knew it was a vireo; hoping for a western vireo as I'm from the Midwest and hoping to get more western species. In looking at my field guide the only vireo that had yellow on all the undersides seemed to be the Philadelphia Vireo, a species that we see during migration here in Northern Illinois.
Previous experience with
this & similar species:
As a bird bander I have identified, held, and banded this species during spring and or fall migration.
