about forty miles from Little Mecattina, and in early August noted 

 twenty or thirty in Bradore Harbor during a heavy gale. Stearns 

 records a specimen from near the mouth of the Esquimaux River, 

 Palmer saw a few in the Straits of Belle Isle, and Kumlien found them 

 abundant from this point to Hudson Strait. It is not unlikely that 

 this and the following species will be found to breed in northern Lab- 

 rador. 



Jaegers occur off shore in some numbers along the Labrador coast 

 in summer. More often we found them in pairs or less frequently 

 in small scattered groups of from four to seven or ten. The first 

 birds seen on our trip were off Cape Harrison on July 19, 1906, and 

 after that we noted them almost daily until our return south to 

 Battle Harbor at the end of July. A number were in the black phase. 

 We saw none in the Straits of Belle Isle. 



The Jaegers were readily distinguished by their easy gull-like flight 

 with frequently a short sail on set wings which curved sharply down. 

 They were constantly chasing one another, as well as the gulls and 

 even the shearwaters. 



Stercorarius parasiticus (Linn.). 

 Parasitic Jaegek. 



Common summer visitor; perhaps breeds in northern part. 



This species occurs along the coast with the preceding in summer 

 and like it, is not known to breed in Labrador. It appears to be less 

 common, however, than the Pomarine Jaeger. We saw several 

 birds whose smaller size seemed to indicate that they were parasiticus 

 while on our way along the east coast, and Coues, Brewster, and 

 Bigelow also mention it as observed by them off the southern and 

 eastern shores. 



Stercorarius longicaudus Vieill. 

 Long-tailed Jaeger. 



Rare summer resident. 



Off the Labrador coast this bird appears to be less common than 

 the preceding two species in summer, but is known to breed in the 

 northern part of the peninsula. Coues ('61) noted a few at sea on the 

 south coast in July, and Brewster saw one July' 20, 1881, near Min-
