The wiiter is under many obligations to Mr. George B. Sennett, of 
Erie ; Prof. August Kock, of Williamsport ; Dr. Walter Yan Fleet, of 
Benovo ; Dr. J ohn W. Detwiller, of Bethlehem — all gentlemen well versed 
in ornithological science — and others* who have spared no xjains to assist 
in securing reliable information relating to our feathered fauna. To Mr. 
Benjamin M. Everhart, of West Chester, a gentleman who deservedly 
ranks as one of - the foremost botanical authjQ^ities in this country, the 
writer is particularly indebted for much valuable assistance in ^he prepa- 
ration of the present work. Mr. Everhart, although sj)ecially interested 
in the study of cryptogamic botany, has for over forty years devoted 
much attention to the study of birds, and while he has become eminent 
in botanical circles his knowledge of the feathered tribes is such that he 
is one of the best ornithologists in the state. The copious field notes 
(manuscript) of Mr. Everhart, also his large and valuable scientific 
library, having been placed at the disposal of the writer, a considerable 
amount of interesting and valuable matter has been given on the follow- 
ing pages that would not otherwise have been obtained.
