Inhabits the same countries with B. Leucopsis ; its nest is made of grass and sea-weed in morasses ; 

 it lays ten or twelve eggs, perfectly white. 



Like its congeners, it is easily domesticated. The trachea and inferior larynx is that of the 

 typical geese, but slightly expanded below the glottis.

An arctic species, and, like most of its genus, is only a winter visitant in these islands ; is easily 

 domesticated. Little is known of its nidiheation, it having only once or twice bred in confinement. 

 The trachea is like that of B. Brenta, but of rather smaller diameter.
