LIST OF BIRDS* 429 



rare. Usually seen in February, March and April. I have a 

 handsome male which was shot by Mr. Comeau April 29th, 



1882. 



131. Larus leucopterus. WHITE- WINGED GULL. Not common. 

 Commonly appears and disappears with the last. Mr. Comeau 

 has shot it as late as May 1st. (Said to breed on the Seven 

 Islands. N.A.C.) 



132. Icarus marinus. GREAT BLACK-BACKED GULL. Breeds and 

 is tolerably common. It is absent only in January and Febru- 

 ary. July 17th, 1882, I found one of their nests on Great Boule, 

 one of the Seven Islands. It consisted of a little coarse grass, 

 placed in a slight depression in the rook and was lined with a 

 sort of pad, about four inches in diameter, of beautiful soft 

 down, on which reposed a single egg. The egg had been in- 

 cubated, but failed to hatch. (Generally lays three to four eggs. 

 N.A.C.) 



133. Larus argentatus Smithsonianus. HERRING GULL. Very 

 abundant, breeding plentifully on suitable rocks. Arrives about 

 the middle or latter part of April, remaining into November. 



134. Eissa tridactyla. KITTYWAKB. Breeds abundantly. Ar- 

 rives late in April or early in May, remaining into December. 

 This and the preceding are the commonest gulls along this part 

 of the coast, and are constantly seen, both singly and in im- 

 mense flocks. They follow tihe receding tide and cover the sand 

 fiats that are exposed at low water, feeling upon the molluscs 

 and other marine animals that abound in such situations. I 

 have seen more than a thousand at one time. 



135. Pagophila ebumea. IVORY GULL. Very rare. Mr. Co- 

 meau shot a male in April, 1877, at Pointe des Monts. The speci- 

 men was presented to the Museum at Bersimis Mission, where it 

 is now preserved. (Dec. 9th, 1895, March 7t(h, 1906, Jan. 5th, 

 1908. N.A.C.) 



136. Chroecocevhalus Philadelphia. BONAPARTE'S GULL. A 

 tolerably common summer resident, arriving late in May. 



137. Sterna macroura. ARCTIC TERN. Very abundant at cer- 

 tain places where it breeds. Mr. Comeau once killed sixteen at 

 one shot flying. It arrives early in June. (A very regular mi- 

 grant, seldom varies more than a day or two in the date of ar- 

 rival. N.A.C.) 



138. Cymochorea leucorrhoa. LEACH'S PETREL. Common in
