(Description:) Field Marks and Identifying Characteristics:	Dark end of the Solitary Vireo spectrum, with a dark blue/"slate" colored head with an obvious demarcation on the cheek creating a stark contrast between the dark hood, and bright white throat. Flanks were a vibrant yellow-green, while back was greenish. The yellow-green wash was apparent in the wings as well where the primary and covert edges showed the color nicely. (see photo)
Song or call & method of delivery:	None
Behavior:	Foraging at mid-canopy
Habitat:	Migrant Trap (deciduous trees)
Similar species and how were they eliminated:	Cassin's Vireo aren't as vibrant, and typically even the darkest individuals hoods aren't this stark. The demarcation on the cheek was also too clean for the usually smudged/faded or blended cheek of a CAVI.
Previous experience with this & similar species:	Have seen numerous times in the midwest and now 3 times in Utah.
