CoBirders --
Got a three-second look at what seemed to be a Myiarchus flycatcher while leading a 3rd grade class around Bluff Lake today. After the students departed, I went back down to the border between Bluff Lake and Aurora open space (go down the stairs and turn right) and quickly re-found the bird, which proved to be an Ash-throated Flycatcher. As far as I can tell, it's a first for Denver County (though in Denver Co, that's not saying much).
Also fun to see was a Warbling Vireo in that same general area. Kingbirds and orioles nesting right there.
Good birding!
