Lone, Chickadees are small black and white arborial birds that both reside here and north of here. In the fall, they migrate thru and like the sunflower seeds to refuel. My apologies to your little black bees, I said I was a hoarder and would like some of them too. This year I am putting up nesting material for the several species of solitary bees and wasps that frequent my small flower gardens. The leaf cutters riddle my roses, especially a climber they seem to favor. Doesn't seem to hurt the rose all that much.
