Hareld is an inhabitant of the Arctic Seas, and is one of the 
few species whose summer migration extends to the highest 
latitudes yet visited, as we find it mentioned in all lists of 
birds furnished by the recent voyages of discovery to those 
desolate and ice-bound regions, where it abides whilst any 
portion of the sea remains unfrozen, and only migrates to the Periodical 
southward when compelled by the consequent failure of food Sasi

our winter visitants, and, as might naturally be expected, is 
most numerous and best known towards the northern extre- 
mity of the kingdom. In the Orkney and Shetland Isles it 
generally appears in considerable flocks late in October or 
about the beginning of November, and continues to haunt
