^ Cooper's Sandpiper {Tringa cooperi). — Asandpiper shot on 

 Long Island, New York, on May 24, 1833, by William Cooper, and 

 named by Professor Baird in honor of its discoverer, has remained 

 unique. This bird is described as identical in plumage with the 

 white-rumped sandpiper, except that there is less of a reddish tinge 

 above, and the white upper tail-coverts are spotted with V-shaped 

 markings of dusky. It is, however, about the size of the knot, with 

 a length of 9.50 inches; wing, 5.80 inches; culmen, 1.25 inches; 

 tarsus, 1.20 inches. This bird is supposed to be a hybrid between 

 the pectoral sandpiper and knot.
