OBSERVATIONS ON CINCINNATI BIRDS. 

 By Frank W. Langdon. 



Since the publication of " A Catalogue of the Birds of the vicinity 

 of Cincinnati,"* by the writer, numerous additional facts relating to 

 the Ornithology of this locality have been brought together, the more 

 important of which form the subject of the pi'esent paper. 



With respect to the various sourc3s from which these additions 

 have been derived, especial acknowledgments are due to Mr. Charles 

 Dury, of Avondale, vvell known for his varied accomplishments as a 

 naturalist and collector, who has kindly placed at my disposal a series 

 of notes, embracing interesting observations on upwards of fifty species 

 of Ohio Birds. Want of space will prevent the reproduction here of 

 iSIr. Dury's notes in full, and I have, therefore, selected chieflj' those 

 relating to species not previously recordetl here, or of especial interest 

 for other reasons. 



Mr. John W. Shorten, of Cincinnati, jNIr. Edgar R. Quick, and Dr, 

 Rufus Raymond, of Brookville, Ind., and the several other naturalists 

 elsewhere mentioned, have contributed notes and information ot value. 



In the numbering and arrangement of the species, the following 

 notes correspond to the oi'iginal catalogue.
