Breeding Notes. — Altogether some twenty nests of this 

 species were gathered, chiefly on sandy islets in the bays of 

 Franklin and Liverpool ; a few of these were also found on 

 islands in the lower Anderson. Fifteen of the nests contained 

 two eggs each, but five had as many as three. The nest was 

 usually a shallow depression in the beach. In one of them we 

 discovered an egg of the black brant. {Macfarlane) 



In the summer of 1896 this species was found breeding by the 

 large lakes in northern Ungava. {Spreadborough.)
