August 2012 – Pinedale, WY
I am pretty certain this is a female Calliope Hummingbird. I think this one is because of the location and markings, and the way her wings sat when rested (some other images, which I haven’t posted here).
May 2010 – Hell’s Canyon, OR
A couple Calliope Hummingbirds spar in mid-air. This was about at mid-elevation in the canyon, during the lush springtime. These birds will often flare their “beard” as a display.
Another photo from the same day. This is a female Calliope… or so I assume given the markings, and proximity to the others.
