1"). Western Sandpiper (247. Ereun^tes occidentdlis). — This 

 bird is much like Xo. 14 in every way. In summer it can 

 be distinguished from it by the brownish-red edgings to the 

 feathers of the back, and usually also by the heavier spots on 

 the breast ; in fall and winter the best method is by compari- 

 son of the length of the bill. Xo. 14 rarely has a bill |- long, 

 while this species has one varying from ^1^^. Its range is 

 mainly through the west, though occasionally it is to be found 



with the eastern spe- 

 cies (Xo. 14) on the 

 Atlantic coast.
