Pisobia cooperi (Baird) 

 Cooper Sandpiper 



Similar to P. fuscicollis in color but ground-color of upper parts brownish gray, with only 

 the least trace of ocherous on some of the scapulars, and upper tail coverts conspicuously varied 

 with broad V-shaped marks of grayish dusky. Length 9.5 inches; wing 5.8; culmi'n 1.25; tarsus 1.2. 



A single specimen of this bird was taken on Long Island, May 24, 1833, and is now in the Smith- 

 sonian Collection, United States National Museum. As no further specimens have appeared, it is 

 believed that it may be a hybrid, or abnormal example of P. maculata.

The Baird sandpiper is a fairly common transietit on the shores of the 

 Great Lakes and the central chain, and is not rare on Long Island. It is 

 a nearctic species, breeding in the arctic region and migrating through the 

 interior of North America to Chili and Patagonia. It was overlooked by 

 the early ornithologists, and can be recognized with certainty only when 

 collected and carefully examined. The migration dates are as follows:
