This Solitary Vireo (Vireo sp.)
was photographed by Martin Reid at Mosque Point, Lake Worth, Tarrant
County, Texas on November 8, 2002. It's behavior was more Cassin's-like, in that it was quite active,
frequently wing-flicking, and sometimes hover-gleaning like a
kinglet.
Note the pure white wing bars and tertial edges, with greenish
tinges to flight feathers (i.e. no yellow) and limited, dingy
flank coloring that is only slightly yellow-tinged. Also, the
light olive-gray of the nape and lower ear coverts extends down
through the mantle and central back, separating the slightly more-green
scapulars:
there is an odd dusky smudge on the chin:
note the rather two-tone head, with a darker front half than
back half, and the darker subloral area that contrasts with the
paler forecrown:
the outer retrices are edged whitish, but with a yellowish
tinge to the edging, and the inner retrices were narrowly edged
yellowish-olive:
