I chuckled at the photo of the American robin in signs of spring. Most American robins do not migrate very far; they simply shift locally due to a change in their feeding habits (from worms in your yards to the berries on trees). If you want to find them in the dead of winter you have only to go so far as the deep woods nearby. For birds, a better sign of impending spring in most locations is to visit your local marsh and see if there are Red-winged Blackbirds. They're truly long-distance migratory birds that are easily identifiable by sight and song.
