Central Florida - Possible Swamp Sparrow

Hello, can someone help please, not sure if this is a swamp sparrow or not.

Thank You

It looks like the pictures of Swamp Sparrows at www.allaboutbirds.org and my guide book. Both list "Lincoln's Sparrow" as a similar sparrow, but the streaks on your bird's breast aren't right for Lincoln's.

Thank You that's what I was thinking.
