Habitat: Willows along riparian area, and tall cottonwoods along golf course.
Similar species and
how were they eliminated:
Warbling Vireo typically has no black in loral area, a more sloped head and longer tail, and brightest yellow on sides of breast and undertail coverts.
Red-eyed and Yellow-Green Vireos both have black eye-stripe extending into the lores, however they have stouter bills and black border between supercilium and crown.
Tennessee Warbler has white undertail coverts.
Previous experience with this & similar species: I've seen Philadelphia Vireos several times, most recently in May 2002, in Kansas and Missouri
