mountains ; and Mr. Wm. Church Osborn procured one at Garrisons, 

 on the Hudson. Miss Anna B. Warner obtained a fine adult male on 

 Constitution Island, on December 27, 1880. The gunners occasionally 

 kill one. It likes to stay about the river marshes in winter.

136. Falco peregrinus nsevius (Gmelin). DUCK HAWK ; AMERI- 

 CAN PEREGRINE FALCON. A permanent resident; breeds. 



I saw a fine mounted specimen in the possession of Mr. Daniel 

 Ward, of Cornwall, which was shot while sitting upon a willow-tree 

 in front of his residence, beside the Hudson. I have seen it frequently, 

 but, chiefly through lack of skill in the use of the gun, have killed no 

 specimens in the Highlands, though I procured one on the beach oppo- 

 site Sayville, on Great South Bay, Long Island, on the 6th of Octo- 

 ber, 1880. There were several Duck Hawks on the beach, preying on 

 small birds. The specimen shot had been feeding upon various 

 passerine birds, which had first been roughly picked, and swallowed 

 in large pieces. Whole legs of the Robin, Alice's Thrush, Catbird? 

 and Warblers were found in its crop. 



Upon the cliffs between West Point and Cornwall, the young are 

 sometimes seen or heard ; but the nest has not been found, and would 

 probably prove to be inaccessible should it be discovered.
