Adel, great shot of the swan dive-those are hard to get. The only real way to tell if you and I are seeing an Allen's is to check the spread out tail besides the green on the back (which could also be a younger Rufous so the tail is the only true test). The Allen's have very narrow, pinlike outer tail feathers where the Rufous' are much wider at the end of the tail.

Here's a young Anna's that was watching for an attack.
