warm days of spring, and the other of migrants from the south that arrive two 

 to six weeks later. 



Thus at Madison, Wis., during nine years of observation, the average date 

 of the first seen for five of these years is April 21, probably a fair average date 

 of arrival for this district, while, during the other four years, the average date 

 is March 27, representing birds that had wintered not far distant. Even at 

 Ottawa, Ontario, which is well toward the nothern limit of the breeding range, 

 the dates of the first seen during twenty-two years are for three years in Feb- 

 ruary, ten in March, six in April, and three in May. The above facts show the 

 reason for the lack of a regular progression in the dates as given in the follow- 

 ing tables.
