NOTES 



''bird study" as merely a pleasant pastime for children and a 

 harmless fad for the outdoor man and woman. It is a matter that 

 touches, not only the aesthetic, but the economic welfare of the 

 country: a matter that has concern for legislators and presidents 

 as well as for naturalists. In this connection it is helpful to read 

 some such discussion as is given in the first four references.

Peter, the gypsy, and Bob, the vagabond, are both famous 

 travelers, and might have passed each other on the way, coming 

 and going, in Venezuela and in Brazil. Peter, like Bob, is a night 

 migrant, stopping in the daytime for rest and food.
