Of the Crow Blackbird of the United States, three well-marked races are now distinguished in the species: one, the common form of the Atlantic States; another occurring in the Mississippi Valley, the British Possessions, and the New England States, and a third on the Peninsula of Florida. The comparative diagnoses of the three will be found on page 809.
