Orange You a Bird Lover?

Pardon the poor photograph. I took it last night close to dark. Several of these clever little bird feeders were hanging from tree limbs outside the adolescent unit where I work, made by the young patients. A week ago, the orange halves were supple and filled with bird seed. Now they have dried but are still quite usable. They are simply halves of oranges that have been scooped out and pieced through with a wooden skewer. A cord for hanging to finish.
