A rare resident in Florida. According to Mr. C. J. Penuock, who 

 found its nest at St. Marks on April 3, its call somewhat resembles 

 the scream of the Red-shouldered Hawk, but is finer and more pro- 

 longed (Auk, vii, 1890, p. 56; see also Scott, ibid., vi, 18b9, p. 243).

"The Rough-leg i.s one of the most nocturnal of our Hawks, and 

 may be seen in the fading twilight watching from some low jiorch or 

 beating with measured, noiseless flight over its hunting ground. It 

 follows two very different methods in securing its food— one by sitting 

 or low tree and watching the ground for the appearance 



on some st 

 of its prey, 



as the Red-tail does; the other by beating back and forth 

 just above the tops of the grass or bushes and dropping upon its vic- 

 tim, after the manner of the ^larsh Hawk, . . . 



" The flight of the Rough-leg is seldom rapid and often njipears
