While birding on the Canon City, CO Riverwalk last week-end I spotted 2 large birds at the top of a tree over the trail and the top pic is what I saw--it took me a minute to realize that this was an Olive-sided Flycatcher from a bottoms-up view.
Given their location, the bottom 2 pics were the best I could get of these birds. I was surprised to see the light yellowish wash on the belly area when I enlarged the pics as they are usually not close enough to see this in pics and I don't think I've ever seen in in binoculars. I did check and
Birds of North America online which said: "Whitish belly sometimes has pale-primrose-yellow wash." I ran into 2 Olive-sided Flycatchers just about an hour ago and at the same location on the Riverwalk (same birds??? maybe using this as a stop-over location to fuel up for the rest of their migration journey). This time they were calling though all I could hear was the 'three beers' part of their 'quick three beers' call. They continued calling back and forth for several minutes and I stayed to enjoy this uncommon serenade--due to serious declines this species is Federally listed as a Candidate for Endangered Species designation.
