BartscJh, Summer Birds of the Oneota Valley. 55 
passed the boundary between the two counties. Winnesheik and Allamakee 
counties. 
{16)-—Accipitercooperi. COOPER’S HAWK. 
Apparently not so abundant as the foregoing, and confined more to the 
timber area. Three young and an addled egg were taken from a nest at De¬ 
corah. Winnesheik and Allamakee counties. 
a7)-~Butes borealis. RED-TAILED HAWK. 
Quite common throughout the valley. Not a day passed but what a num¬ 
ber of these birds were noticed. Several young and adults were shot from the 
boat. Winnesheik and Allamakee counties. 
a8)—Buteo lineatus. RED-SHOULDERED HAWK. 
By no means as common as the last. Allamakee county. 
{19)—Buteo latissirrius. BROAD-WINGED HAWK. 
Several of these birds were seen but none secured. Winnesheik and Alla¬ 
makee counties. 
{20)Saliactus leucocephalus. BALD EAGLE. 
A bird, which I took to be of this species, was seen flying about a cliff on 
June 28th, in Allamakee county. 
{21)—Falco peregrinus anatum. DUOH HAWK. 
A pair of birds which I am inclined to refer to this species were noticed 
sporting about one of the steep escanpments. The graceful swift movements 
and size cause me to believe that it must have been this master, as he is the 
only one able to perform such feats of wing. Allamakee county. 
{22)'^Faleo spavarius. SPARROW HAWK. 
Not common in the valley proper; only a few observed and these frequented 
the more exposed situations. Winnesheik and Allamakee counties. 
{28)—Bubo virginianus. GREAT HORNED OWL. 
Quite common; a young bird whose head was still covered with down was 
shot. The birds keep close to the water and on several occasions I flushed them 
in early morning from fallen trees which extended into the water. The fact 
that this happened repeatedly led me to believe that Bubo might at times vary 
his diet by catching a fish. Is it not possible that the fish might be attracted by 
his glowing eyes? Winnesheik and Allamakee counties. ^ 
{2Jf)SyrniuTYV7viebulo8U7n. BARRED OWL. 
Seems to be more restricted to the hills and hill sides. Winnesheik and 
Allamakee counties. 
{25)—Megascops asio. SCREECH OWL. 
The querulous wailing note of this bird was heard many an evening in our
