The savannah sparrow is a small passerine found in open spaces through out North America. They breed through most of Canada and the northern half of the United States. Some savanahh sparrows at the southern edge of the breeding range are year round residents while those in most of the range migrate to the southern United States, Mexico and Central America during the winter when food is not as available.
There are seventeen recognized subspecies of savannah sparrows. The subspecies vary mostly in their coloration. Several subspecies, like the ipswich subspecies were once considered their own species. The ipswich savannah sparrows are larger then most the other subspecies. They breed on the coastal islands of Nova Scotia and winter on the Atlantic coast.
