Observation details

Continuing birds found by Nieman earlier in the week. Heard giving sharp trilling call (VEFL-esque) a few times, but mostly silent. Vocalization diagnostic (eliminating the nearly identical Couch's Kingbird). In flight underside of the tail was consistently dark (no white outer retrices as in Western or cream terminal band as in Cassin's). Underparts citrus yellow with a slate gray head. Breast greenish as was the back. Bill appeared thicker than I might expect for Western Kingbird, but perhaps thinner than I'd expect for Couch's. Relatively long billed. Dark "mask" not terribly well defined. Whitish throat. Seen on the west side of the street (across from and slightly south of the water park) from the alley between the neighborhood and a sports complex (labelled "Rio Pecos Tennis Shop" on Google maps). The bird that was photographed was working the elm trees along the main entrance road (Park Dr.)
