Hi PotatoJoe, I'm not sure where you're located, but you may want to check out tufted titmouse -- classic "peter" song. I've linked below for you. Have fun birding by ear. Cathy in SWPA Here is a link that might be useful: tufted titmouse info

The second photo I saw of this bird looked really familiar. I think it is a cardinal bird. Some times I saw this bird, my friends told me it was a cardinal. This picture looks pretty good. Where did you take it? Local or a place of interest? By the way, if I want a bird like this, can you show me how to get it?

No, it's an eastern bird. Bewick's would be more appropriate for your area at this time of year, possibly Pacific wren depending on how far south you are in California. Regardless you definitely have a wren! If the bird house is being used, there is probably two birds, the male and female! Congratulations! Having birds chose your yard to raise their babies is quite an honor, in my opinion.
