I think the one in the forefront is a chipping sparrow. Not sure of the other. The bush row along my fence line is full of house sparrows but these two looked different....smaller.
Close one is a chipper for sure, rear one looks like a song sparrow.
I believe the one in the front is a Chipping Sparrow, although I'm not sure that the far one is a Song Sparrow.
The supercilium doesn't look right for a Song Sparrow (then again, I could be wrong). Is it possible it is also a Chipper?
The one in the back is so much grayer. The only picture in my guide that comes close is a swamp sparrow.
I never realized there were so dang many different sparrows until I started visiting this site and looking in the guides?
The Sibley Guide
You wouldn't find young sparrows at this time of year, and also Swamp Sparrows are usually found in swampy areas.
There you go, Raptor said it best.
Chipping Sparrow, Lincoln's Sparrow.
