I saw it on the street when I was walking the other day: a single feather. Dark, elegant, alone. From a crow, perhaps. At home we have feathers all over the house from our sweet parakeet, Hermes. But his are electric blue, or sometimes darker pinfeathers or fluffy white downy bits that float in the air like dust motes. We humans molt dead skin and fingernail parings. How much more lovely the gifts birds leave behind.
