many unnamed points and rocks just at or above tide which serve 

 as feeding ground for birds, also occasional nesting places. 



The above island descriptions may prove tedious, but it is 

 thought best to add them, that the reader may thoroughly 

 understand the bird-life environments, and also have a definite 

 idea as to where the islands and places mentioned are located. 



In giving the species below, the islands inhabited by a named 

 species will be given in succession, together with the estimated 

 number of birds of that species nesting on each respective island, 

 the total also being given at the close of the enumeration. 



Unless otherwise stated, the birds mentioned in the list below 

 are breeding residents. The number opposite the name of each 

 respective species is the number of that species in "Handbook of 

 Birds of the Western United States," by Forence Merriam Bailey.
