Fall Migration. — As is true of most ducks, there is a 

 southward movement in August, but it is not until early 

 September that many appear south of the breeding 

 grounds, and in the course of two weeks a few birds 

 find their way even to the Gulf of Mexico, arriving there 

 by the middle of September. Some early dates are : 

 Erie, Pa., Sept. 6, 1893; Alexandria, Va., Sept. 13, 1890; 

 Long Island, Sept. 15, 1903; Rhode Island, Sept. 4; east- 

 ern Massachusetts, Sept. 11; Montreal, Sept. 3. The 

 main flight is a whole month later, bringing the birds in 

 large numbers to Chesapeake Bay the middle of October 

 and to the coast of North Carolina late in that month. 

 Some very early migrants have been seen in west central 

 Texas Sept. 4; at Corpus Christi, Tex., Aug. 18, 1902, 

 and at the southern end of Lower California, Aug. 29. 

 The last ones leave the Arctic just about the time the 

 first reach the Gulf of Mexico; the last were noted at 

 Point Barrow, Alaska, Sept. 7, 1882 ; Kowak River, 

 Alaska, Sept. 14, 1898; St. Michael, Alaska, Oct. 10; 

 Fort Franklin, Mackenzie, Sept. 27, 1903. Large flocks 

 begin to leave southern Minnesota the middle of 

 October, and most have departed by the 1st of No- 

 vember.
