The birds are arranged in the order of their arrival from the South in
the vicinity of New York City. Nos. 43, 46, 47, 51, 57, 60-64, 67, 68,
70-72 winter in the Southern (chiefly Gulf) States. The remainder winter
in the tropics and reach the Southern States a month or more before they
arrive at New York. Compared with the dates here given for New York
City, Washington dates are from ten to fifteen days earlier; Boston,
about a week later; northern Ohio, eight to twelve days earlier;
northern Illinois, six to ten days earlier; southeastern Minnesota,
about the same as those for New York.
