I Have No Idea What These Are....Other Than Cute!!!

I took these three pictures all in the same day, over at the Buford Trout Hatchery. I actually do no that the last one is a Bluebird! The first two birds were in the same tree, but I don't think they were the same species. I know the second one is a flycatcher of some sort, and I had thought Mockingbird for the 1st, but I still need to check it out.
