A Report on the Nesting Birds in the Vicinity of Riverview Park, 

 Allegheny, Pa., for 1906 



By WILLIAM G. PITCAIRN 



THESE observations were all made in the vicinity of Riverview Park, 

 Allegheny, Pa., the greater part in the park. 



Riverview is a natural park of about two hundred and fifty acres, 

 mostly wooded hills and much hawthorn growth, situated about two and 

 one-half miles from the city of Allegheny. Being a picnic park, there is 

 something going on almost every day during the spring and summer, and I 

 think that this fact tends to limit the number of breeding birds; but, in 

 spite of the conditions, the birds seem to prosper fairly well, their chief 

 enemy being the small boy, who wantonly destroys many nests. 



There has been a considerable increase, I think, in the number of birds 

 in this locality, particularly in the cases of the Baltimore Oriole, the 

 Downy and Hairy Woodpeckers, and the many species of migrants.
