410 THE CANADIAN NATURALIST. [Dec. 



Least Terji, S. frenata, Gamhel. — Apparently very rare. I 

 only examined one specimen, which was shot about the 10th of 

 September, 1887. This bird was probably blown across to New- 

 foundland by X.W. gales, which often prevail at that season. 



SULID.E, 



Common Gannet, Sula bassana (^Linn.^ — A very common 

 summer migrant and constant attendant on the large shoals of 

 mackarel and herring, which are migratory in spring and fall, the 

 seasons of which are indicated to the settlers by gannets and gulls. 



Phalacrocoracid.t: — The Cormorants. 



Common Cormorant, Graculus caibo (^Linn.) — A summer 

 migrant and very abundant at some breeding stations along the 

 coast. 



Douhle-crested Cormorant, G. dilophus (Swain.') — Equally 

 abundant with the preceding ; both species fly in the form of the 

 letter Y reversed, and breed in colonies: G. dilophus is said to 

 breed in trees in Hawk's Bav, Newfoundland. 



C0LYMBID.E. 



Loon or Great Xortliern Diver, ColymbusTorquatus, Brann. — 

 A very common summer migrant to Newfoundland, where it is 

 called ''Loo," not Loon. At this season nearly every lake and 

 large pond is tenanted by its pair of loos; I say by its pair, 

 because I believe the same pair, unless destroyed or continually 

 disturbed, invariably return to the same site for many years. In 

 1867 a female loo hatched her two es2;s on a rock in Parson's 

 Pond, within gunshot of a house of one of the settlers. The house 

 was not usually tenanted during summer, but some of the family 

 were daily going to and fromit. Tie same pair of birds (?) had for 

 many years hatched their young on this rock, which sloped gra- 

 dually into the water, and was nowhere at that season more than a 

 foot out of water. "When built on an island, or by the side of a 

 lake, I have never known the nest more than three feet from the 

 water, and very rarely so much : the birds are very awkward walk^ 

 ers, although wonderfully strong on wing, and breed on many ol' 

 the lakes in the interior of Newfoundland; not only on the plains 

 but on the high table-land, upwards of two thousand feet above 

 ihe sea. Loos are often taken in the salmon-nets of the settlers: 

 1 got a very fine adult male taken in this way on July 10th, 1867.
