territory, as in the cases of such intrusive forms as Cardinal, 

 .Yellow-breasted Chat and Carolina Wren that have formed- 

 permanent settlement here. In studying out the problems 

 presented it is well to bear in mind the fact that Prof. E. L. 

 Mosely seems to have conclusively prooved that within almost 

 historical times there was land connection broken but by 

 marshes and streams of comparatively narrow width between 

 the Ohio and Canadian shores. 



Taken all together, the bird life of Point Pelee, the islands 

 adjoining and the opposite American shore forms a subject of 

 absorbing interest and ground where migrational phenomena 

 of the Great Lakes can perhaps be studied to better advantage 

 than anywhere else in this section. There are many such 

 problems that seem to have a glimmer of light thrown on them 

 from work done here and should results warrant they will 

 form the grounds of subsequent papers. As a basis for such 

 future work and as a matter of present record the following 

 list is put forth by the authors : 



A LIST OF THE BIRDS OF POINT PELEE. 



1. Columbus auritns, Horned Grebe. 



Without doubt a regular spring and fall migrant as at Detroit, 

 Midi. Two seen on the Lake Pond, October 15, 1906, and listed by 

 Harry Gould (Ottawa Naturalist, Vol. XV, 1901, p. 16), September 

 19, 1900. 



2. * I'lHiiiiimbus podiceps, Pied-billed Grebe. 



A common migrant and undoubtedly a regular breder in consider- 

 able numbers. We have not observed it as yet in the spring during 

 our May visits, but at these times little marsh work was done 

 and they could easily have been overlooked. The species increases 

 in abundance from early September and are common by the middle 

 of the month on the ponds, though we have yet to see it on the Lake. 

 They were very common during October, 1906, and appear to remain 

 until driven out by the formation of the ice. In 1905 there were still 

 11111 n hers to be seen October 29.

Mr. Saunders found a nest during the first week in June, 1884, near 

 the west side of one of the ponds and remarks, "They were then

 mens have been examined by them personally.
