part only was explored. The broad valley of the Ohio and 

 the Scioto valley are the migration paths for the birds from 

 the northeast to southwest and north to south. The rest of 

 the two counties consists of various series of hills and small 

 ravines and valleys. Along the creeks and rivers small 

 groves are yet to be found, while the hills are covered with 

 woods, sometimes in tracts of 300 to 400 acres. The for- 

 ests consist mostly of deciduous trees, sparingly interspersed 

 with a few pine trees at a few localities. This accounts for 

 the presence of some rare species, while the bottom lands 

 are drawing new species in every year. The climatic condi- 

 tions are too well known to be mentioned in this connection. 



^Md one knows better than the writer, how incomplete is 

 this list of Southern ) Ohio birds; but not one record is 

 given that has not been carefully scrutinized by the writer. 

 The period of observation runs from Aug. 15, 1894, to July 

 1, 1,902, but a busy professional life has made it impossible 

 for the author to do "what he ought to have done." The 

 excuse for making up this list is the fact that practically 

 nothing is known of the ornis of Central Southern Ohio, 

 and that by it a gap in our knowledge of the birds of Ohio 

 may at least partly be filled out. The writer will be glad 

 of any corrections and any just criticism concerning this list. 



The birds of this region are represented by 216 species 

 which may be divided in the following way: residents, 42; 

 summer residents, 61; regular transients, 64; irregular and 

 rarer transients, 27; winter residents, 10; accidental vis- 

 itors, 7; extinct, 2; introduced, 2. 



Unless otherwise stated the species here enumerated are 

 represented by specimens in the author's or local collections.

 in both counties on the different streams and ponds. Arrivals^
