FRANKLIN'S GULL 



quills blackish; tail gray at base, broadly black

2. Larus franklini (Richardson) 

 Franklin's Gull 



Chroicocephalus franklinii RIDGWAY, Birds of N. and 

 M. Amer., VIII, p. 641, 1919. 



Length 355 mm. (14.00 in.); tail 100 mm.- 

 (4.00 in.). 



Sexes alike. Very similar to Larus atricilla, 

 both in plumage and other characters, though 

 slightly smaller. The bill is stouter, and the 

 black of the outer primaries does not extend to 

 the ends, their tips being rather broadly white. 



A migrant from the interior regions of the 

 United States, where it breeds about fresh water 

 lakes and marshes, apparently frequenting the 

 sea coast only in its winter haunts.
