RARER BIRDS OF AMES REGION 
215 
in a willow near the Veterinary Buildings. This specimen re- 
mained on the same limb for about two hours. 
Sparrow Hawk 
( Falco sparverius sparverius ) 
Common in Iowa but, strange to say, the sparrow hawk does 
not appear to be common at Ames. It was reported twice. One 
was seen April 28, 1918 (B. R. E.) and a pair was observed 
April 6, 1919. 
Barn Owl 
( Aluco pratincola) 
The writer obtained no record for the barn owl. They were 
observed, however, in the larch grove in 1921 (J. E. G.). 
Long-eared Owl 
( Asio wilsonianus ) 
The only evidence of the presence of this owl at Ames was ob- 
tained by Professor Guthrie who found the feathers of one under 
& tree which evidently was the haunt of a barred owl. 
Short-eared Owl 
( Asio hammeus ) 
Short-eared owls were observed flying about during the fall 
of 1921, according to Professor Guthrie, who states that one 
was shot near the dairy farm. This specimen is now in the 
college museum. 
Barred Owl 
( Strix varia varia) 
Although this species is very common in parts of Iowa only 
a single questionable record for this large predator was obtained. 
During the latter part of April, 1919, several persons reported 
the seeing of a large owl. On April 25, 1919, Dr. Fenton, of 
the Zoology Department, reported seeing an owl “larger than a 
crow.” Judging from the description he gave, this owl must 
have been the barred owl. 
Ruby-throated Hummingbird 
(Archilochus colubris) 
The abundance of the ruby-throat in any locality is largely 
dependent upon the prevalence of such nectar-producing flowers 
as the honeysuckle. Flowers of this kind are not plentiful at 
Ames, and where they occur they are usually cultivated. Records ;
