Tongue Teaser

I know the proper name for the little black capped birds in my yard is "Chestnut-backed Chickadee", and they are a special treat to have here. But, they are very like the "Black-capped Chickadee" and I often slip in referring to them by that name, because before I was a Birder, I wasn't aware of the differences. Well, here's a Tongue Teaser for all my Birder Friends: (its my own species)
