reopening this thread. identification was never made.
About once or twice a day I see a bird on my feeder that resembles the Black and White Warbler except that its breast is predominately black while all the pictures of the Black and White Warbler show a predominately white breast. It has the front-to-back white stripes over the eyes, and in the wings and breast like all the pictures show. When I used the wonderful Whatbird attribute search, nothing comes close except the Black and White Warbler.
btw, I use Wild Bird Centers Patio Mix in my feeder. This is a mixture of sunflower chips, hulled millet and peanut pieces. I live in the northeastern Atlanta suburbs.
