1IM THE WILSON BULLETIN No. 61. 



August 29, 1907. These latter had been noted for several days in the 

 same spot, and going over the next day with the purpose of taking 

 recording specimens, we found them all gone. Though no specimens 

 h.-ivo boon taken, Mr. Brewster has examined series from the sur- 

 rounding localities, London, Ontario; Detroit, Michigan; and Oberlin, 

 Ohio; and has pronounced them of this sub-specific form. 

 105. *Empidonax minimus. Least Flycatcher. 



One of the most abundant Flycatchers. We have found it com- 

 mon on all our May visits, and in September, until shortly after the 

 middle of the month. In 1905 their numbers culminated the 9th, but 

 there were still a few when we left the 14th. In 190G they were com- 

 mon during the first three days of September, but were gone by the 

 time of our return trip, the 15th. In 1907 we did not notice any for 

 the first two days, but the 26th of August they commenced arriving, 

 and by the 28th and 29th were very common. After this they gradu- 

 ally decreased, though they were still not uncommon when we left 

 the Gth of September. Our latest fall date is September 14, 1905. 

 10G. *0ctocoris alpestris praticola. Prairie Horned Lark. 



Prairie Horned Larks are usually to be found along the east beach 

 and in the waste clearings near the end of the Point near the shore. 

 We have noted a few on each visit, but found them especially in 

 March and October. Specimens taken March 9, 1907, were evidently 

 breeding or preparing to do so. From the reports of Jones on the 

 Ohio shore, directly opposite, and Saunders, of Rondeau, a few miles 

 east along the Ontario shore, we expect that both 0. a. alpestris and 

 O. a. lioyti will eventually be found here in the winter, but as yet we 

 have received no specimens to verify our expectations. 

 107. *Cyanocitta cristata. Blue Jay. 



We have found the Blue Jay common at all times, but more abun- 

 dant in fall than spring. During the hawk flights of 1905 and 1906 

 they were much harassed by the Sharp-shins but, as they are per- 

 fectly able to take care of themselves and kept pretty close in the 

 grape vine tangles, it is not probable that they suffered much, unless 

 it was from the nervous strain of being continually on the outlook. 

 But who ever saw a Blue Jay suffer from nervousness? In fact once 

 within the shrubbery, they seemed to rather enjoy the situation, and 

 from their safe retreats hurled joyous epithets at their baffled ene- 

 mies. Saunders also notes the ability of the Jay to keep a whole 

 skin against the hawks, and we have only once found the remains of 

 a hawk-devoured bird of this species. 



October 14, 1906, we noticed a very interesting migration across 

 the lake. All morning long we saw large flocks passing out the 

 Point. In the afternoon we followed them to the end and, though 

 most then had passed, we witnessed one small bunch of perhaps fifty
