“Bustards, Laughing Geese, Ducks, and large Gulls, make their appearance here from the 27th to the 29th of April; Snow Geese and Black Geese about the 15th or 16th of May, when the other kinds become plentiful. They have mostly passed by the end of the month, though some, especially the Bustards, are seen in June. The White Geese and Black Geese breed only on the shores of the Arctic Sea. They return in September, and early in October, flying high, and seldom halting.” Sir John Richardson seems inclined to the opinion that the common Brant is here alluded to; which, however, we cannot consider so probable as that it is our present bird. So well acquainted with the water birds of Europe and America as he is, it could scarcely have been supposed by Mr. Murray that he had never seen so abundant a species as the common Brant. Besides, the white ring round the neck, as described, is exactly applicable to the Black Brant now before us, and its uniting on the front of the neck forms a peculiar character sufficient to distinguish it from any other species.
