Unexpected visitor this morning. It looks like a Cordilleran Flycatcher to me. They visit in the spring and summer, but this seems awfully late. Location: Boulder County, Gross Reservoir, alt. 7600 feet. Eyering appears not broken in other images, color is olive drab, might come across a bit blue here. Crest is more towards the back of the head than I have seen in summer -- willow flycatcher? Any clues appreciated.
