(52 THK BIRDS OF GREENLAND. 



138. American Robin. (Merula migratoria.} 

 A chance visitor to South Greenland. 



139. Wheatear. (Saxicola cenanthe.) 



A summer resident ; breeds everywhere. Eggs laid from 

 May 30 to June 28. Number of eggs in a set, 5 to 8. 



From the above it will be seen that the birds of Green- 

 land are drawn more from America than from Europe. 

 About one half of the different species are merely chance 

 visitors, and of these only a small number are found in 

 North Greenland. 



[Of the one hundred and thirty-nine species here enumer- 

 ated one is extinct and fifty-three are merely accidental 

 stragglers, while twenty-four others are so rare that they 

 might be classed with the accidentals, leaving but sixty- 

 one species that should be recognized as regular inhabitants 

 of Greenland ; and of these several are of quite uncommon 

 occurrence. M. C.]
