At the feeder

by John Curr
(Buffalo, New York)

I'm rather new to birding, and bird photography, and after exhausting my copies of the Audobon guide, and Crossley's ID guide, I was hoping the astute readers could help me here. Although this little Rufous/Red fellow looks common, its the curious breast color/pattern that keeps me coming back to figure it out. Curiously, the chest is all rufous/red except for the patch, nearly dead center which is either white, or the same color as the predominant feathers around the beautiful chest/breast color.

Though I took the first picture of this bird more than a month ago, it didn't at first appear remarkable. But, I keep coming back to it. I only ever see one individual and as you can tell from the bird behind it, it doesn't seem to get noticed by the other birds and I have even seen it feeding on the ground alongside a Northern Cardinal.
Your thoughts?

The bird on the right looks like a House Finch.
