CACKLING GOOSE. 



Ridgway writes me, "is a seasonal character, and may 

 occur in all the sub-species. It fades out in summer and 

 reappears with the fresh molt in autumn. Of this fact 

 I had proof in a domesticated Hutchins's goose which 

 my father had for some eight or ten years." The back 

 and wings are slightly paler than in the Canada goose, 

 while the feathers of the breast are perhaps a little 

 darker. The tail feathers are i8 to 20, as in the Can- 

 ada goose; the bird's length is from 33 to 36 inches, 

 wing 18 inches or less. This sub-species is also called 

 the white-cheeked goose. 



Branta canadensis minima Ridgw.' 



The cackling goose bears the same relation to the 

 western goose that Hutchins's does to the Canada 

 goose, except that the difference in size is much greater.
