This Calliope Hummingbird may be a hybrid. The blue color is very unusual. The blurry hummingbird in the foreground is a female Calliope that was using the feeder when this male showed up.

Close up crop of above photo.

This is the same hummingbird as above taken seconds after the above shot. A slight blue color can be seen on the inner throat area.

Same Bird as above but no blue coloring can be seen.
