Scott and Caleb, I believe this is juv female Black-chinned. Completely green central tail feathers rules out Calliope, which should have blackish tips. Crown is grayish (Ruby-throat would be greener). It looks like it is pumping its tail up and down, a behavioral trait of Black-chinned but not Ruby-throated). Bill is short due to young age. Broad-tailed would have more buff on flanks and rufous base of outer rectrices (tail feathers).
