Thanks Deb, Nancy, Billy and Chris. This little guy is always entertaining. He chases the other sparrows around, even gets after the House Finches and Goldfinces. I think the others are just playing, cause this guy is about the size of my thumb, maybe half the size of a normal house sparrow. 
Chris, I spend a lot of time with my yard birds too and this one is the only one that comes close, and it's more like he just doesn't see me or knows he can get away if I make a sudden move. Or, it could just be his character. 
Here's one more, after he moved. He moved around several times and kind of nestled down into the seeds like it was a beanbag chair each time.
