92 The Wilson Bulletin — No. G3. 



One was taken September 5, and anothei* seen each day of the 13th, 

 14th, and inth, lflC5, in the waste fiekls near the end of the Point. 

 It has not l)e(Mi noted on any other occasion. 



174. *Deiulroica discolor. — Prairie Warhler. 



September 5, 1905, Klugh took a juvenile male of this species in 

 the dense thickets back of the eastern shore, just beyond the cross- 

 road (see Auk XXIII, 1900, p. 105), making the thii'd recorded speci- 

 men of the species for Ontario. This is our only record for the 

 Point, though Saunders thought that he heard one singing Septem- 

 ber 20, 190(i, and Taverner thonglit tiiat he recognized' anotlier indi- 

 vidual September G, 1907, that he failed to secure, on the same 

 grounds where Klugh took his. It may be found to be a regular 

 though rare migrant on the Point. 



175. *8eii(nis aurora pill us. — Oven-bird. 



Surprisingly scarce in spring. This was an unexpected condition 

 to meet anywhere in this section, for the Oven-bird is one of the com- 

 monest summer woodland residents we have. May 14, 1905, we saw 

 but one, and none the 20th-21st of the same month, 190G. May 31 

 and June 1, 1907, when all migrations were so disorganized, five and 

 eight were noted on the respective days. None were noted the first 

 three days of May, 1908, by Swales and Wallace, though it is true 

 that they were then hardly to be expected as at that time they had 

 not as yet arrived about Detroit. From this data we conclude that 

 but few, if any, breed on the Point, and that practically all seen there 

 are migrants. In the fall they are fluctuatingly connnon. Septem- 

 ber 5-15, 1905, they were noted nearly every day, but were more com- 

 mon during the early days of the visit. In 190G they were conmion 

 the first three days of September, but a few were noted on the 18th, 

 20th and 21st. The fall of 1907 but two individuals were seen August 

 30 and 31. These may have represented breeding birds as the season 

 was late and it was evident the migrants of this species had not yet 

 arrived. 



17G. *8eiuriis iwrchoracensis. — Water-Thrush. 



The Water-Thrush is, in all i)robability, a regular, if not a com- 

 mon spring migrant, though we have met it but once during the ver- 

 nal migrations, May 15, 1905, when several were seen along the in- 

 side of the western road on the edge of the marsh. Dr. P>rodie re- 

 ports that, during his July trip of 1879, Water-Thrushes were "very 

 common." Judging from adjoining Michigan standards this was 

 rather surprising, as it is with us but a scarce migrant, and has yet 

 to be discovered breeding with us. On our arrival at the Point, Sep- 

 tember 4, 1905, there were considerable numbers present, most of 

 which left the night of the 5th, for after that date but few singles
