Gray Flycatcher in Central Oregon

I went camping with my 5-yr-old grandson near Lake Billy Chinook in Central Oregon. As the morning sun began to warm the juniper/sage habitat around our tent, several Gray Flycatchers appeared to be finding many active insects. Just as the book says, the rounded head of this species is a good field mark distinguishing it from the similar species in the Empidonax group of small flycatchers.
