I think both are Broad-tailed, which are certainly more common in your area. Note the white between the eye and the bill on the male and the rusty flanks on the female. Listen when the male flies - it makes a whistling sound unlike the humming of a Ruby-throat. Later in the summer you will have to worry about distinguishing female Broad-tailed from Rufous and Calliope - that will be more of a challenge.
