Blue-gray Gnatcatcher (from what I can tell)

So I was out with Russ and had my camera (you never know what you'll see).  Saw a bird I did not recognize (not even from a book).  I got fairly close (as you'll see).  Looked through my Iowa bird book and nothing.  So I Googled "gray and white bird" and then checked Images.  I'll let you decide, but I believe I saw a Blue-gray Gnatcatcher.  They do live in Iowa.  I am including pictures I took and then also including photos from BirdsofIowa.com Click here to see page from this website.



Same as above but just blown up.
