number breed and pass the year. In the winter they are joined by a much Iar<'-er 

 number driven out by the ice from more northern places, where this barricade 

 compels them to move to more open water. Among these, Mr. Boardman informs 

 me, it is no uncommon thing to find individuals of this species in their full black 

 plumage in midwinter. 



Off the coast of Norway the JVIessrs. Godman found this bird Avintering in the 

 latitude of Bodo. During the summer it was everywhere common alono- the entire 

 coast of Norway, where its eggs are much sought for, and esteemed as a great 

 delicacy by the natives. 



In the British Islands it is more abundant in the more northern portions. It is a 

 resident species in the north of Ireland, and among the Hebrides and other Scottish 

 islands it breeds more or less commonly ; Mr. ^Macgillivray met with it among the 

 Hebrides. Mr. Salmon found it among the Orkneys in 1831, where it is called the 

 " Tyste." He found it breeding on a small holm eastAvard of Papa-Westra, where 

 it was very numerous, and would scarcely move off the rocks when approached. 

 In every instance two eggs were found together, deposited on the bare ground. He 

 describes the egg as white, slightly tinged with green, blotched, spotted, and speckled 

 with ash-gray, reddish brown, and very dark brown. The length is 2.25 inches ; the 

 breadth 1.50. The first covering of the young birds is a grayish-black down ; and 

 the feathers, which soon appear, are mottled with black and white. The young 

 of this species do not leave the nest until perfectly fledged, and able to provide 

 for themselves. Then the care of the parents ceases, and they do not even keep 

 company with their young. Their food is chiefly crustaceans and small fishes. 



In the summers of 1850 and 1851 I found the Black Guillemot breeding in the 

 Duck Islands, Grand j\Ienan. Their eggs were never more than two in number, and 

 appeared to be placed on the bare rock, without any preparation, e v^n of pebbles, to 

 keep them dry. They were placed under loose overlying rocks, the broken surfaces 

 of which left room for the ingress and egress of the bird. They Avere usually Avhere 

 they could not be reached by the arm, and could only be secured with the aid of a 

 short pole with a forked end. The birds were shy, and not infrequently betrayed 

 the locality of their nests by flying from under the rocks at our approach ; which, 

 had they not done, they might have escaped observation. The eggs were all fresh ; 

 and it is possible that a little later more than two might have been found in a nest. 



In the spring of 1836, in the months of April and May, this bird Avas still present 

 off Nahant, and specimens Avere procured, one of Avhich is referred to by Audubon. 

 They Avere obtained Avithout difficulty from an open boat ; for, though the birds are 

 expert divers, they Avould ahvays rise Avithin a short distance of the place Avhere they 

 disappeared, and could be shot before they had time to diA-e a second time. 



Giraud does not include this species among the birds of Long Island ; but Mr. 

 LaAvrence giA^ es it as found in the neighborhood of Ncav York. It is quite common 

 in the outer waters of Massachusetts Bay as far as ProvincetoAvn. South of the Cape 

 it is said to be much less common. 



Audubon states that this species ahvays lays three eggs ; but I think that he must 

 be mistaken — at least I never met Avitli more than tAvo eggs under one bird; and 

 this I Avas universally assured was the prevailing number. Dr. Bryant, in his 

 paper on the Birds that breed in the Gulf of St. LaAvrence, Avhere he found it breed- 

 ing everyAvhere in abundance, also states that he never found more than tAvo eggs 

 laid by the same bird. This Avas noticed on a small island Avhere there was nothing 

 indicating that the bird had been disturbed, where the greater number had but just 

 begun to incubate, and none of the eggs had been hatched.
