Geographi-

 tion. 



Bonaparte's Sandpiper, like its two nearest allies the Curlew Sandpiper and the 

 Japanese Knot, has the upper tail-coverts white, more or less streaked with brown. The two 

 central upper tail-coverts are, however, often only tipped with white. From both these 

 species, as well as from the Knot, it may easily be distinguished by its short bill, which 

 rarely measures more than "9 inch from the frontal feathers. 



In its seasonal changes of plumage it closely resembles the Japanese Knot, but the 

 summer chestnut of the upper parts is less brilliant though more generally diffused. 



Bonaparte's Sandpiper breeds in the arctic regions of the American continent, from 

 Greenland to the Mackenzie River. At Point Barrow it only occurred as an accidental 

 straggler. It passes through the United States and the Bermudas (Reid, Zoologist, 1877, 

 p. 477) on migration, and winters in the West Indies, Central America, and the whole of 

 South America. It was originally described by Azara from Paraguay, where it has recently 

 been obtained by Rohde (Berlepsch, Journ. Orn. 1887, p. 36). It is an occasional straggler 

 to Europe, and has been said to be a resident in Central Patagonia (Durnford, Ibis, 

 1878, p. 404), and to breed in the Falkland Islands (Abbott, Ibis, 1861, p. 157) ; but these 

 statements require confirmation. 



It appears to be the American representative of the Curlew Sandpiper, and to bear 

 the same relation to that species that the Japanese Knot does to the Common Knot.
