The Migration of Thrushes 



FIRST PAPER 



Compiled by Professor W. W. Cooke, Chiefly from Data 

 in the Biological Survey 



With drawings by Louis Agassiz Fuertes and Bruce Horsfall 



WE believe that all field -students of American birds will endorse the 

 statement that few ornithological papers have been published pos- 

 sessing greater enduring interest and value than those on the ' Mi- 

 gration of Warblers' which Professor Cooke has prepared for BiRD-LoRE. 

 We have, therefore, special cause for congratulation that, with the kind 

 permission of the Biological Survey, Professor Cooke has consented to treat 

 other groups of birds in the same equally thorough manner. — Ed.
