Female house finch?

First, I want to thank each person who responded so quickly and thoroughly to my last post.

I am wondering now if this bird is perhaps the female house finch (the last one was the male - perhaps this is his mate). This little lovely just appeared at my feeder a few minutes ago.

 

 

This is SUCH FUN!

There is another bird that I can't quite get a good picture of, but would like help identifying. They are dark grey/black on top, and white underneath. They are quite small. I will post the best pic I have of him - sorry though - it isn't too clear. What might this one be?

 

 

Thanks in advance for your expertise and words of wisdom to this rank-and-file n00b!
