I take that Western Wood Peewee ID back ...

Having looked at a couple more references (Sibley, Stokes and the
National Geographic) I'm now fairly sure that the birds I saw are
missing features that would make it a Western Wood Peewee. Namely no
peak at the back of the head, the underside was lighter than the
Peewee (no "vest" as in Sibley) and the undertail coverts were much
lighter (and not smudges as in Sibley) and the head was a darker than
the throat and breast.

So the birds I saw were most likely an Empidonax flycatcher.

My field notes also say "mid to short tail". I think that might be
interpreted as "broad tail" rather than "narrow tail". That and range
gives me WILLOW FLYCATCHER as the most likley possibility. Others
might be HAMMOND'S FLYCATCHER or DUSKY FLYCATCHER or PACIFIC-SLOPE
FLYCATCHER but all seem to not quite match my notes.

Ah, "The most peeweelike flycatcher" says Sibley at the top of page
326 on the WILLOW FLYCATCHER :-)
