This European species is a common summer resident in Greenland. 

 It has been found nesting in Labrador, and there is evidence of its 

 having bred at Godbout, Province of Quebec (Merriam, Auk, 1885, 

 p. 305; Comeau, ibid., 1890, p. 294). South of these points it is of acci- 

 dental occurrence. 



Mr. Saunders writes: "From early spring onward the Wheatear is 

 to be seen, jerking its white tail as it flits along, uttering its sharp chack, 

 chack, on open downs, warrens, and the poorer land; ascending the 

 mountains almost to the highest summits. . . . 



"The song of the male is rather pretty, and the bird also displays 

 considerable powers of imitating other species."
