DR derBRUCER - I have seen five at the most....usually the biggest one eats at the crock on the ground where I put the sunflower seeds, and the others watch from a distance.....they nibble on the bird seed under the feeders. Once he's gone they fight each other to get sunflower seeds until everyone has had some.
The snow has made it difficult and haven't seen them for a couple of days. I cleaned the snow away from the sunflower seeds and put plenty out, but the cardinals are enjoying them right now.
