that any one person will be able to fill all of the spaces for a 

 single species, but rather in the hope that you may find some 

 point upon which you can give information. Any informa- 

 tion at all relating to any species of our birds will be received 

 with thanks and will be used somiehow in the final report. 

 Please do not neglect to return these blanks because there does 

 not seem to be enough upon it to pay for the postage. If 

 there is anything at all upon it let the compiler judge of its 

 value. One question answered is well worth while. 



Mr. Frank L. Burns has kindly consentel to undertake the 

 study of the life history of the Broad-winged Hawk, with your 

 cooperation. He desires information past, present, and future 

 concerning this species, upon all aspects of its life. The ac- 

 companying blanks for breeding notes can be used as far as 

 they go in giving the life history of this hawk. You will con- 

 fer a lasting favor upon Mr. Burns and upon the science of 

 ornitholog}' if you will not allow this appeal for notes to grow 

 cold and so finally entirely escape your mind. Send him what 

 vou have now.
