TAVERNER AND SWALES, ON BIRDS OF POINT PELEE. 51 



8. *Hydrochelidon niura mnrumnn-nHia, Black Tern. 



A common summer resident and breeder. Sets of eggs were taken 

 by Saunders in 188-1 and they were evidently nesting or preparing to 

 do so May 31, 1907. September 12, 1905, is our latest fall date when 

 we witnessed an interesting migration of the species. Early in the 

 morning a large number were observed passing southward along the 

 east beach. Many paused on their way, alighting on the net stakes 

 about half a mile out in the lake until every stake was covered. 

 Nearly all were immatures. By noon all had passed. 



9. * I'lKiliK-rocara.r (lil<ti>lmx- I ><mble-crested Cormorant. 



.March 10, 1907, we discovered the remains of a specimen of this 

 species on the eastern shore that we were informed had been killed 

 the previous fall. The head was preserved for record. 



10. Merf/diixcr americamis. American Merganser. 



Undoubtedly both Mergansers occur regularly on the waters ad- 

 jacent to the Point, though we have not noted them personally. 

 This is the species the gunners seem the better acquainted with and 

 they report it as common during migrations and through mild win- 

 ters. 



11. * /yo/>//m////r.s' ciH'iillatus, Hooded Merganser. 



Reported by the gunners as a common migrant. A tine male sent 

 us taken November 13. 190G. 

 IL'. *.lm/x hochas, Milliard. 



Without doubt a common migrant and a common though limited 

 breeder, as reported by the gunners. Birds seen and taken Septem- 

 ber 1. I'.Mir.. were likely raised on the marsh. Locally all females are 

 known as Grey Ducks by the gunners, who regard them as of a dif- 

 ferent species. This confusion is likely caused by the taking of 

 males in the "eclipse" plumage when for a short time during the sum- 

 mer moult it assumes the general plumage of the female. 



13. *.lm/.v oh.sT/n-(/,--Plack Duck. 



.1. ohnt'Hni is a more abundant species than bocJiu* and is reported 

 by the gunners as a common breeder. Sannders saw a pair waddling 

 about the marshes June 3, 1884, and May 30, 1907, he and Taverner 

 noted ducks in singles and nocks over the marshes to the number of 

 twenty or more that we took to be of this species. In all probability 

 late migrants will be found to be the form niltriix's. though so far 

 we have been unable to examine specimens from there later than 



October in nnoro. 



14. Chaulefasmus .v//r/>r/-//x. Gadwall. 



Gardner seems to know this duck, though he says it is not common. 

 Though it likely occurs rarely, until >pcHmens are secured its statin 

 must remain hypothetical. 

 l.~. * \cltinii furuliitnixix. Green-winged Teal. 



I'ndouhtedly small numbers are of regular occurrence during mi-
