Tom - I think you goofed. That last shot is another of a White Throated Sparrow...
I think this one is a Chipping Sparrow but not positive. Hard to get a good ID on a lot of the sparrows. I have this one and the White Throated on my feeder every day, cool little birds. They spend more time on the ground than the feeder though.
Forgot about this thread when I got these, spotted some Bobcats not long ago when at the lake looking for Woodducks.
They were originally chasing a squirrel but I'm pretty sure they'd like this guy too...
