WHAT BIRD IS THIS? 



BIRD LORES 

 BIRD CHART 



WILL TELL YOU. 



It figures 62 representative species of our 18 families of Perching 

 Birds, gives their range, numbers and family characters. With its aid 

 one so readily grasps the structural differences distinguishing one fam- 

 ily of birds from another, that it soon becomes an easy matter to refer a 

 bird to its proper family. 



We Will Give a Copy of This Chart 



With a free copy of our December number, containing Ernest Thomp- 

 son Seton's article on "Journal Keeping," to every one now subscribing 

 to BIRD-LORE for 1903. If you are a genuine student of birds you 

 cannot afford to lose the help BIRD-LORE will give you. In a series 

 of papers to run through the year, Frank M. Chapman will tell how to 

 make the best use of your eyes and opportunities in studying the nest- 

 ing habits of birds. You may also want to call on one or more of BIRD- 

 LORE'S 50 Advisory Councilors for advice or information. We pro- 

 pose to publish the portraits of the members of the Council in 1903 

 forming, in fact, an album of 50 prominent American Ornithologists. 



The annual subscription to BIRD-LORE is One Dollar. For this 

 occasion we offer five subscriptions for $4.00. If, therefore you secure 

 four subscriptions your own will cost you nothing.
