Brown-crested Flycatcher, Myiarchus tyrannulus

Brown-crested Flycatcher
Myiarchus flycatchers are a regular identification challenge in Arizona, where three
similar species overlap. I got the assurance of an experienced Arizona birder that this
was a Brown-crested -- based on the large bill, relatively bright and extensive yellow
on the underparts, and particularly the extensive rufous running all the way to the tip
of the tail. Dusky-capped has less rufous, and Ash-throated is brown at the undertail
