 heaviest on the larger end. 



EREUNETES 0CCIDENTALI5 Lmin: 



Western Semipalmated Sandpiper. ' 



This species may be distinguished from E. piisillits by its longer bill, which is oftentimes ' 

 1.25 inches in length, while E. pitsilliis rarely if ever has the bill one inch in length. Occasionally 1 

 examples of the Western Sandpiper have the bill less than one inch, and in such cases it is 

 almost impossible to distinguish them from the winter examples of E. piisilhis j therefore it is 

 perhaps as well for the sportsmen to consider all of those birds having bills less than one inch 

 in length to be E. pjisillus, and if it is important to have the identification absolutely accurate, 

 they could easily obtain the opinion of some professional ornithologist to settle such a fine point.

 on the East coast.
