Saundkrs — On Summer Birds of Western Ontario 153 



this l)ird had ah-eady been noticed in summer at two or three 

 other locaHties in Ontario in other years, and one was heard 

 sing-ing- near London on June 5, 1909, and may possibly be 

 nesting" there. Another of this species was heard al)out 

 three miles from the east base of Point Pelee, which strength- 

 ens the conviction that they are to be found more commonly 

 near the base of the Point than elsewhere on the mainland. 



At six miles southeast of Amherstburg- we located another 

 Chat, in fact we heard two at once, but the note of the second 

 one was so peculiar that it necessitated special investigation to 

 determine the author. The first one was accompanied by its 

 mate and they were doubtless nesting- in the scrub at that 

 point. These birds are rather rare on Point Pelee and we 

 were not very confident of finding them on the mainland, but 

 at Renwick. about forty miles farther east anc^ther one- was 

 noted in a somewhat similar location, where it was doubtless 

 nesting. 



Another note of interest was the discovery of a breed- 

 ing ground of the Piping Plover. About six or eight pairs 

 of these birds were scattered along the lake shore beside the 

 marsh near the mouth of the big creek a few miles from the 

 Detroit River. One nest was found with four nearly hatched 

 eggs and the other birds were manifestly concerned at our 

 presence. Favorable nesting grounds for these birds are not 

 to be found very often. The others reported so far for the 

 north shore of Lake Erie are Point Pelee, the Rond Eau 

 sand bar and the Long Point. It is to be doubted if there are 

 more than two or three other localities at which these birds 

 are found in the nesting season, while on Lake Ontario the 

 Toronto island is the only point that I know of where the 

 species nests. 



The Savannah S|)arrow which is an abundant bird at Lon- 

 don was rare throughout all the territory covered and was 

 everywhere outnumbered by the Grasshopper S]:)arrow of 

 which we recorded as many as 10 in one dav. 



The Rough-winged Swallow was noted in two places, 

 single birds onlv, the other being doubtless on the nest. As
