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. 



Rivervievv^ 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.
