Old & New Birds-Wed. Wings

I believe this is a male (first year) House Finch,although I had to scramble for the Stokes Field guide to help with identification as this is the first yellow one I have ever seen. 

Brown-headed and Bronzed Cowbirds are common to our area but here again this is a new bird for me. He was not Mr. Popularity at the feeder as the other birds would not tolerate him and succeeded in running him off.
