Savannah Sparrow ?

After looking on the internet and my bird book, Savannah Sparrow is my best guess.  I went to the refuge this morning hoping for baby owl shots.  Mama owl was asleep on the nest baby was not visible.  There wasn't much else out a few ducks and little birds.  Spent the afternoon helping my friend with a few Lightroom questions. We are having such beautiful weather it's like summer, I am on my way to enjoy the sun for a little while before making dinner.
