American Robin

I spied an American Robin this morning when I was walking on the treadmill.
It's short and stout with brick red round belly and tiny orange beak.
The head is black and back is dark grey.
 This robin would no doubt be considered obese with such a full belly.
It sits on top of a tree branch outside the fitness center window and grooms its feather leisurely.

Then it suddenly dives down fast from the branch for some delicious bugs or worms.
