    Beautiful pictures Glen, I enjoyed all of them, but
    particularly of the Rufous Hummingbird.  This series
    of diagnostic photos is a real treat.
    I too am struggling with the Dusky and believe the
    broad yellow lower mandible, blocky head, off-white
    throat, and short primary projection track more
    closely with Willow Flycatcher. Willow also has a
    "whit" call, for what it's worth. Thanks for sharing
    your photos!
