Behavior: We first observed the bird perched near the trunk on a branch near the top of a tall tree. When it moved it hopped along the branches, and hopped short distances from branch to branch. It stayed near the trunk as it foraged for food along the branches. We saw the warbler catch a moth and it took a couple of minutes before the bird could pick off the wings and maneuver it's catch so that it could finally swallow it. It stayed in an open area near the trunk after it ate the moth. It sat there and looked around for a couple more minutes. We then lost sight of it as it flew out of the tree. We searched the nearby trees and relocated the bird about twenty minutes later as it flew into a russian olive tree close to where we first observed it. We were able to watch the bird for approximately two more minutes as it again hopped through the branches near the trunk.
Habitat: Small patch of mixed woods including both cottonwood and russian olive trees.
Similar species and
how were they eliminated:
Grace's Warbler is similar, however, this bird definitely had a triangular black patch on the face, a white eyebrow stripe, and a white patch near the ear area. The Grace's Warbler does not have these black and white markings on the face.
Previous experience with this & similar species: We have seen Yellow-throated Warblers in Texas

We've observed numerous Grace's Warblers in Utah, including at Devil's Canyon, Bryce Canyon, and Zion National Park.
