 Macrorhamphus griseus (Gmel.). 



DOWITCHER. 



Rare transient visitor. 



This species may breed in Ungava but the evidence at hand does 

 not prove that it is more than an uncommon migrant on the Labrador 

 coasts. Turner speaks of it as rare at Fort Chimo, and mentions 

 specimens from that place and from Davis Inlet. Coues also obtained 

 an immature bird in southern Labrador on August 23, 1860. 



The coast of Labrador is largely rocky, and in most places bold 

 and precipitous. Salt marshes, sand beaches, and even pebbly beaches 

 are few and far between; most of the shore birds, therefore, are not 

 tempted to tarry long on the coast during the migrations. 



Tringa canutus Linn. 

 Knot. 



Uncommon transient visitor. 



Stearns found it an uncommon migrant on the southern coast and 

 in his account of "Bird-life in Labrador" records having obtained a 

 specimen on September 30th. Coues also shot a few immature birds 

 after August 21st on the south coast (Henley Harbor) and Palmer 

 secured two females from flocks of White-rumped Sandpipers on the 

 Mingan Islands. 



Arquatella maritima (Briinn.). 



Purple Sandpiper. 



Rare transient and winter visitor. 



The only positive record we have for this species is that of Audubon 

 who speaks of shooting specimens at Bradore on August 4, 1833. 

 Turner did not observe them. As they breed in Greenland and re- 

 main off the coast in winter if the sea be open, it is probable that they 

 occur more commonly in Labrador than our records would 'admit. 

 It is possible that they may yet be found breeding in northern 

 Ungava.
