Update, October 31, 2004:
this has been Identified as a Hammond's
Flycatcher by some expert western birders.
This empid was found by Martin Reid and photographed by Jim Halff
at the Halff Brothers
Ranch, near Pearsall, Frio County, Texas on September
23 2004: in the field it was noted that the eye-ring was significantly
expanded at the rear, and that it had a distinct, rather shaggy
crest; it also flicked its wings and tail quite a lot - but note
that this bird came in to an owl tape; it did call a few times
when it first came in - a slightly disyllabic upslurred note:
