April and the other of unoartain date mark the northern limit from which 
birds have been reported. 
From these notes we learn that after leaving Utah part of the pintails 
go to California to winter in the interior valleys, while others cross to the 
Groat Plains and go southward to the Galf Coast in Sexas. She spring migra¬ 
tion carries these latter individuals northward through the plains again, east-

records in the Missouri Valley drainage in the United States ceased after 1915 
as in the following year spring shooting was prohibited by Federal Law and no 
further return came from ducks killed at this season, a It nay be noted that 
only a small part of the pintails found in early fall in the Salt Lake Valley 
nest there as the species is only moderately common as a breeder in that region. 
Migrants from other regions, probably to the northward arrive early, even in 
4k 
June, and continue to gather in suitable areas until fall.

Baeords for the present species give some idea as to the average length 
of life of a pintail after it reaches maturity. Of birds banded in September, 
1914, one was taken in April and one in Bovenber 1916, one in January, 1917, 
and one in December, 1917. Of those marked from August to October, 1916, one 
was shot in December, 1917, two in January and one in Hovember, 1918, while 
one was fortunate enough to escape until the last of Sovember 1920, a period 
of slightly more than four years.
