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 FA.LCO. Linnseus. 



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, robnst ; 

 claws long and sharp.
