The first one's a female Rufous/Allen's. (Most likely Rufous, but Allen's isn't impossible these days.) The second one looks like a young male, with the gorget coming in, again Rufous/Allen's. I agree that the third one looks like a Ruby-throated, although I can't see enough to rule out a vagrant Black-chinned.

Thank you both! I think the most common ones in my area are rufous and ruby-throated. 

I just looked through my sibley book, and practically see no difference between rufous/allen's and ruby-throated/black-chinned.

Is it not possible to identify them with the photos I have?

The last bird does not look like a Black-chinned to me.

You cannot tell the species or gender of the rufous/Allen's shots you have

although I agree with psweet on the probabilities.

Sorry, this is not a definitive method for determining gender in hummers.

Well, it is to a point. Given the date, the first bird almost has to be a female - a young male should be well into it's pre-basic molt by February, so there should be something coming into the throat. The second bird does have feathers coming into the gorget, and they're at the corners rather than the center. Female Rufous and Allen's have any iridescent feathers confined to the center, according to Pyle.

Rufous and Allen's are extremely difficult -- unless you have a male with a rufous back, the only sure-fire way to distinguish them is by the shape of the outer tail feathers, and that requires excellent photos. Ruby-throated and Black-chinned are a little easier, and I think I agree that this is a Ruby-throated. I'm basing that largely on the longer tail, which appears to project well beyond the tail feathers, and what little we can see of the primary tips.
