ly into Ontario. In Wayne Co. he finds it most common dur- 
ing the latter half of April and early May when all the way 
from singles to two or three hundred may be seen at one time, 
always circling high in the air and gradually working north- 
ward. The earlier birds are all or nearly all adults and the 
majority ‘from the middle of May to June are birds in the 
plumage of the second vear. Few adults alight in the county, 
but many of the junior do so and some remain in suitable lo- 
cealities. until the middle of June. At Detroit he has seen more 
of the birds passing over the city than elsewhere (probably 
from more frequent opportunity) but they do not seem to be 
concentrated at any special point along the river, and all cross 
into Ontario. Detroit is practically at the head of Detroit river 
and while this hawk is rare north of the city limits (Lake St. 
Claire), it is more or less common on the south side (Detroit 
river). He believes that the bulk of the S. E. birds work N. 
and E&., and the Michigan examples are all from the eastern 
Mississippi valley. 
Swales gives the time of arrival in southeastern Michigan, 
as late April and early May. Norman A. Wood gives four 
dates for Ann Arbor, the earliest being April 15, 1905, and the 
latest May 25, 1897. 
For Oberlin. Ohio, Baird gives March 1-10 for the earliest 
arrival based upon ten vears records, while Jones gives about 
the middle of March for same localities. Prof.’ Jones gives a 
very interesting account of several flights witnessed by him 
near Cedar Point, Ohio, (which lies nearly opposite ‘Point: 
Pelee, Ontario). The two most conspicious of these flights 
were May 2, 1904, when a large company, associated with 
6 Red-tailed, 4 Red-shouldered, 3 Rough-legged, 3 Sparrow, 
2 Marsh Hawks and 2 Bald Eagles, were watched from the 
top of a sand-stone knoll two miles south of Oak Point. The 
Broad-wings disappeared to the N. E., but all the others re- 
turned apparently to their nesting places. The other occasion 
was April 29, 1907, at Rye Beach, when the numbers were too 
great to be counted. These Broad-wings were near the ground 
when first seen, but rapidly ascended in spirals, all the while
