DUCK HAWK. 423 
Dr. Kirtland named it in his list on the implied authority of Audubon. 
Mr. Read refers to it, but not as an Ohio bird. Mr. Kirkpatrick men- 
tions a specimen taken by Dr. Sterling in the vicinity of Cleveland. 
Mr. Langdon, on the authority of Mr. Dury, notes: “A single specimen, 
female in inmature plumage, taken twenty miles east of Cincinnati, in 
November, 1878.” Doubtless this bird is of not unfrequent occurrence in 
northwestern Ohio. I have never meet with it in this vicinity. 
The nest of the Goshawk is placed in trees. The eggs, usually four, 
are dull greenish-white, sometimes faintly spotted with yellowish-brown. 
They measure about 2.30 by 1.80. 
GENUS FALCO. Linnzeus. 
Bill with a distinct notch and prominent tooth. Nostrils circular, with a central 
tubercle. Wings long and pointed; tail rather long and wide; tarsi short, robust; 
claws long and sharp.
