After considerable time spent trying to identify this bird, I believe it is a Hammond’s Flycatcher. Is that eye ring oval enough; is the bill short and dark; does it have a small, bull-head … whatever that means … to confidently identify this bird correctly? I know for sure it is a flycatcher, one of 17, and not the boxy-headed vermilion flycatcher which I see all the time here in SW Arizona as it is a resident at my elevation!
While this flycatcher can be seen from Alaska, USA to Nicaragua on its potential migration route, it is known to be in winter at elevations between 3000 – 5500 feet in my area. Now that I have added this bird to my life list, I will keep my eyes open when on the mountain roads this winter and look forward to its return in the spring.
