618 ANSER CANADENSIS. 



yellowish-green colour, thick-shelled, rather smooth, three 

 and a half inches long, The period of incubation is twenty- 

 eight days. The young very soon accompany their parents to 

 the water, but pass the nights on land, under their mother. 

 The parents remain with their brood until the following 

 spring. 



Having been long fostered in England, in some parts of 

 which it is not uncommon in a tame or semi-domesticated 

 state, it is said occasionally to attempt a free life, and to roam 

 in small flocks ; sometimes, however, it appears perfectly 

 wild, and, possibly enough, individuals may occasionally mig- 

 rate into England. I am not aware of its having been met 

 with in a state of liberty anywhere in Scotland.
