Chipping Sparrow

Description:

dark brown/tan with lighter brown stripes and looks like they are grey on the bottom. We have A LOT of these in our back yard (30+ at a time)

Habitat:

this is our backyard and these little guys come a lot and in big groups

Notes:

The very last picture, with the lone fat bird, I assume it is the same as the others, but it seems much fatter and maybe a little lighter in color than the others so I am not sure. It flew in the tree and I wasn't able to get another shot of it.
