ATTENTION, OHIO OBSERVERS. 



Information is especially desired concerning the status or 

 occurrence in this State of the following species. Some of 

 them are merely under suspicion as probabilities; some are 

 just coming to recognition as newly elaborated sub-species; 

 others, once reckoned common by our ornithological fathers, 

 have unaccountabK' passed from our ken; others still, while 

 well known residents of our State, occupy variable areas, or 

 occur within limits not satisfactorily determined. In prepar- 

 ing a book on the Birds of Ohio the writer is both discover- 

 ing the weak places in his own armor, and waking up to the 

 fact that many likely species are being allowed to pass un- 

 noticed by the majority of observers. Any information re- 

 ceived will be gratefully acknowledged in these columns or 

 in the pages of the book:
