Sanderling. 



Calidris arenaria, LlNN. 



THERE is tardly a known bird which has a wider range than the Sanderling. 

 Roughly speaking, its breeding range is circumpolar, and very far north, 

 and in spring, autumn, or winter, it is to be found on the shores of the rest 

 of the world, excepting Australasia, which it does not approach nearer than Java 

 and Borneo. In Asia it goes southwards to Ceylon, in Africa to the Cape, in 

 America to Patagonia. It breeds sparingly in Iceland, Greenland, Smith's Sound 

 and the Parry Islands, and probably in most parts of the Polar regions, north of 

 lat. 73". From its great numbers, it is fair to conjecture that its breeding grounds 

 must be very extensive. Few satisfactorily authenticated Sanderling's eggs are in 

 existence, nevertheless. On our coasts, Sanderlings begin to appear about the 

 middle of August, and, as is usual with Waders, a few old birds, in rather faded 

 summer dress, are first to appear; by the end of the month, young birds of the 

 year are plentiful. A few may be found during the winter months, but, as a 

 rule, they leave us about the end of October for the south. In April they reappear, 

 but in smaller numbers, on their northward journey, some few remaining till mid- 

 May, or even June, and being then in full summer plumage.*

* The large flocks of Sanderlings which visit the N.W. coast of England in May and June, sometimes to 

 the number of three thousand birds in a flock, are in changing plumage, very few of them having quite assumed 

 the nuptial garb, though in process of doing so.— H.A.M.
