rather irregular in Missouri, seldom seen in March, oftener in 
early April, but summer residents cannot be expected with 
certainly before the latter part of the month (Widmann. ) 
Mixed flocks of Red-tailed, Red-shouldered, Broad-winged 
and Cooper’s Hawks were encountered in Iowa, April, 1862, 
when “hundreds slowly sailed over in the peculiar gyrating 
manner of these birds. They formed a long loose flock, ex- 
tending both to the northward and southward as far as could 
be seen, the whole company occupying more than an hour in 
passing a given point” (Allen). 
The earliest during 16 years’ observation by Dr. I. S. Trost- 
ler in Douglas and Sarpy Cos., Nebraska, was April 1; yet H. 
E. Lee noted a flock of 15 on the Missouri River at Pierre, 
Douglas Co., South Dakota, Mar. 25, 1906. Preston mentions 
the many pleasing freaks oi flight as the great company moves 
onward in the regions of the Red River of the North. Geo. 
E. Atkinson finds it early in May regularly, his first or earliest 
record being May 1, 1897, at Portage la Prairie, Manitoba. 
On April 27, 1892, a flight of hawks which lasted all day, 
was observed at Chicago by Dunn. At one time in an opening 
of a small woods called Hog island, 14 birds were in sight. 
Most of them appeared to be medium-sized, perhaps one-fourth 
were small. Mr. Craig shot one of the latter which proved to 
be a Sharp-shin, and Mr. Dunn shot two of the former which 
were Broad-wings. They were rather tame, several alighted 
among the trees. They were all flying south or perhaps S. W., 
while the woods was full of other birds migrating northward. 
The day was warm and pleasant, with light thunder showers 
in the morning and the wind south, strong. 
J. Claire Wood writes that along the Port Austin shore in 
Huron Co., Michigan, there is an annual spring flight. The 
local hunters spoke of shooting hundreds for sport and Arnold 
met with flocks there while after Eagles’ eggs in April. They 
follow up the shore of Saginaw Bay. The village of Port 
Austin is separated from the extreme north point (Point Aux 
Barques) by two miles. more or less wooded and he could get 
no information from this point but believes they crossed easter-
