THE CONDOR 



A MAGAZINE OF 



WESTERN ORNITHOLOGY. 



EDITED BY WALTER K. FISHER. 



THE CONDOR is indispensable to 

 every serious bird student. 



During 1904 THE CONDOR will be 

 profusely illustrated with photographs 

 of wild birds from life. More than 

 half the magazine will be devoted to 

 articles dealing with the popular side 

 of ornithology— habits, life-histories, 

 exploration — from the pens of many of 

 the leading Ornithologists of the coun- 

 try. The series of portraits of promin- 

 ent ornithologists will be continued, 

 and there will be numerous short 

 notes, as usual. 



Have you seen the January- February issue 

 with the full-page portrait of the California 

 Condor, painted by Louis Ajrassiz Fuertes, 

 and K. H. Beck's remarkable picture of bird 

 life among the Galapagos Islands?
