These hummers seem to have a large population on the top on Camelback Mountain in Phoenix. They're still too impatient to pose very well, but their antics are always fun to watch while recuperating from the steep ascent up Echo Canyon. The Broad-Tailed is the most common Hummingbird in Arizona and in the Southwest up to Southern California, and it's nice to have colorful birds that stay in Arizona year-round, and in good numbers.
Their ruby-red throats also have a bright green on the sides, which I had never been able to see without the use of still shots. They have the shiny green backs common among hummingbirds, and the females (pictured first) lack anything more than a few freckles on their throats.
