    Details

    Spotted with Mark and Lyann at 9am at (38.527398, -121.795638), in a tamarisk just west of the rope swing. We noticed a large solitary vireo moving through the trees with a warbling vireo, and initially thought it was a Cassin's, but noted that the flanks and vent were almost a highlighter yellow color, and the head was very dark with a crisp line of contrast between the cheek and the clean white throat. The white supraloral is very well-defined with strong contrast to the crown, the outer rectrices show white edging around a dark center, and the bill appears to show a bluish base. Unfortunately the bird remained above us the entire time we could see it (about 3 minutes), so we weren't able to check for contrast between the head and the back color, but from what we saw in person and what is visible in my photos, this bird appears much closer to a BHVI than a CAVI.
    
    We lost track of the bird when it flew south across the creek, and seemed to keep going.
