Prom these data we learn that after leaving Utah part of the 
pintails go to California to winter in the interior valleys* while 
others cross to the Great Plains and go southward to the Golf ooast 
in Sosa®. 'Wm spring migration carries the latter individuals north¬ 
ward through the Plains again, eastward as far as western Missouri, 
ani north at least into southern CJaaaada. Spring records In the Missouri 
Talley drainage ceased after 1915, as in the following yoar spring Shoot¬ 
ing in the United States was prohibited by federal lew, and no farther 
return oame from ducks killed at this season*. 
It may be noted that only a small part of the pintails found 
in early fall in the Salt take Talley 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 tee,

Banding records furnish 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 November, 1916, one 
in January, 191?, and one in December, 1917, Of those masked from 
August to October, 1916* one was shot in December, 191?, two in January 
and one in November, 1918, while one was fortunate enough to escape 
until the last of November, 1920, a period of slightly more than four 
years*
