Henninger — On Birds of Seneca County, O. 49 



The same painstaking care is exercised in determining the 

 species as that exercised in the writer's List of the Birds of 

 Middle Southern Ohio (Wilson Bulletin, September, 1902). 

 It would not be proper to publish this list without making 

 grateful acknowledgment to Prof. 'E. M. Klecknier, of Heidel- 

 berg University, Mr. Hergenrather, of the Tififin Fire Depart- 

 ment, and my indefatigable young friend, Mr. Karl J. Heil- 

 mann, of the Tiffin High School, for much efficient help ren- 

 dered the writer in many ways. 



1. Colymbus auritus. — Horned Grebe. A rather rare winter vis- 

 itor. One shot December 20, 1902. 



2. Podilymbus podiceps. — Pied-billed Grebe. A rare summer res- 

 ident, but abundant transient. Middle of April to October 6. 1902. 



3. Gavia imber. — Loon. A rare transient, more common in form- 

 er years. 



4. Gavia lumme. — Red-throated Loon. November 7, 1904, one 

 was observed for ten minutes on the Sandusky river, then shot at, 

 when he flew away. 



5. Lams argentatus. — Herring Gull. Abundant spring tran- 

 transient. April 1 and 2, 1904. Not seen in fall. 



6. Larus Philadelphia. — Bonaparte Gull. Not common spring 

 transient. April 1 and 2, 1904 Not seen in fall. 



7. Sterna hirundo. — Common Tern. Occasional spring migrant. 

 1904. 



8. Phalacrocorax dilophus. — Double-crested Cormorant. Two rec- 

 ords, one about thirteen years ago, one shot in spring of 1902. 



9. Pelecanus erythrorhynchos. — American White Pelican. Two 

 records. See Wilson Bulletin No. 53, December, 1905, page 126. 



10. Merganser amerlcanus. — American Merganser. 



11. IVlerganser serrator. — Red-breasted Merganser. 



12. Lophodytes cucullatus. — Hcoded Merganser. 



All of the above three species are in local- collections taken in pre- 

 vious years in the county. Lately M. serrator has not been taken 

 here, while the other two have become rare. 



13. Anas boschas. — Mallard. Abundant transient in both sea- 

 sons. Seen as late as June 3, 1904. 



14. Anas obscura. — Black Duck. All specimens taken in the 

 county belong to this form, rubripes not having been found. Nov. 

 2G, 1903.

 None lately.
