The Birds of Warren County, O. 127 



ular occurrence in the county, the irregularity of my own ob- 

 servations must account for the fact that I have overlooked 

 them and have no other records to which to refer. Birds of 

 this class may be distinguished in the following list by the 

 quotations attached to their names, the Cincinnati quotations 

 being from Dr. F. W. Langdon's list of Cincinnati birds, and 

 those from the State at large from Dr. Wheaton's work on the 

 birds of the State, published in the report of the Ohio Geolo- 

 gical Survey. Any other authorities are named. The birds 

 to which no quotations are attached are birds which have oc- 

 curred in the State, many of them being recorded from the 

 vicinity of Cincinnati. They are birds w^hich are liable to oc- 

 cur in the county any year (except a few species here included 

 on the probability of their occurrence in former years, of which 

 some record may yet be found), but such occurrences will in 

 all probability be found to be very irregular, and many of them 

 w'ould come under the head of accidental.
