CLOSED: Can you ID these CA Hummingbirds?

I was just awed by the vast numbers of hummingbirds in southern California. One giant tree in Peter's Canyon was so full of them you could hear them yapping at each other before you even saw the tree. They were also HUGE! Everything is supposed to be bigger in Texas but those CA hummers were giants compared to ours. Ours are barely bigger than a bug. Of course, we have very big bugs here!

Anyway, despite the quantity and size, I didn't get any good pics, but hoped y'all could help ID anyway. I think this one is a Black-chinned even though his chin is way blacker than any of the pics I have of a Black-chinned.

Hummer 2

Hummer 3 -- I think this is hummer 2 flying away, but just in case I'm wrong, I'm calling it #3!

Hummer 4

Hummer 5 - last one

The first one, maybe an Anna's Hummingbird? http://www.birds.cornell.edu/AllAboutBirds/BirdGuide/Annas_Hummingbird.html

That certainly seems possible. The first one is probably the only one that can be ID'd. Wish my pics were better! Number 4 might be an Anna's too. Hmmmm.

Yep, Anna's for #1.

The rest are silhouettes, not much can be done with them, except that the longish tail projection on #4 also points to Anna's. Probability would also suggest Anna's for all of them, as that's the only hummer that is resident in California, except for Costa's right down on the Mexican border (going by the map in Sibley).

#4 could very well be Costas Hummingbird, they winter in Southern Cal: http://www.hummingbirds.net/costas.html

Thanks for your help! I knew it would be hard with these lousy pictures. If my family hadn't been pulling me along, I would have found a spot with good light and hung out until I got some good pics! Oh well. Family first right? If only I could get them as excited about birds as I am!

Sorry, not Costa's for #4; on Costa's the wingtips are just slightly longer than the tail, not shorter.
