Vegetable food. — Fruit was found in 5 stomachs and vegetable refuse 

 in 1 . There were a few seeds of blackberries or raspberries, and these 

 were the only things that could have been the product of cultivation. 

 The rest was wild fruit of no economic value. 



Summary. — The habits of the Acadian flycatcher do not lead 

 it to the garden or orchard, and its food has little direct economic 

 interest. It does not catch many useful insects and, as it does not 

 prey upon any product of cultivation, it may well be considered as one 

 of those species whose function is to help keep the great flood of insect 

 life down to a level compatible with the best interests of other forms 

 of life. 



TRAILL'S AND ALDER FLYCATCHERS. 



(Empidonax trailli trailli and Empidonax trailli alnorum.) 



The Traill's and alder flycatchers, one or the other of the two forms, 

 occupy in the breeding season the whole of the United States except 

 the southeastern part south of northeastern Texas, Arkansas, and the 

 mountains of West Virginia, and extend north into British America. 

 In winter they retire entirely be} T ond the southern boundary of the 

 United States. While the two subspecies differ in their geographical 

 range, they agree with each other, and differ from most other fly- 

 catchers, in a preference for bushy thickets along streams rather than 

 for more open country. Unlike most flycatchers they do not usually 

 select a naked twig or stake for a perch, and the nest is generally built
