The Migration of North American Sparrows 



los 



for the winter. Three forms, breeding in Alaska, come south in winter to 

 Cahfornia; but not enough data have as yet been secured to formulate their 

 times of migration. Nearly all of the dates gi\en in the following tables refer 

 to the eastern bird, and it is particularly to be noted that this is the case 

 with the Mackenzie records and those for Kotzebue Sound, Alaska. Note 

 also the variations in speed of migration; forty days are occupied in the 

 1,000 miles from Missouri to Manitoba, and only thirty days for the 2,500 

 miles thence to northwestern Alaska.
