Thank you for posting these additional photos, most of which look much more
yellow than the previous ones. One of the most yellow looking is:

http://www.flickr.com/photos/dominikmosur/5116075289/in/set-72157625326006442/

but in that photo the entire underparts are suffused with yellow including
much of the throat, mid-breast, belly and undertail coverts. This pattern
is not found on Cassin's or any other vireo in the Solitary complex.

Anomalous yellow can occur in photos and in the field for a number a
reasons. One is the filtering of light through green leaves, or reflection
off of green or yellow leaves.
