RED-SHOULDERED HAWK. 3O7 



Notes on the White-tailed Kite. There was a pair of this species about the northern end of 

 Merritt's Island, Fbrida, in the spring of 1866 and I quite frequently saw them there, and Mr. Wm. 

 Peterson sent me a pair which he procured near the same place the next year. 



FALCO SPARVERIOIDES. •- 



Cuban Sparrow Hawk. 



Sp. Ch. Form and size similar to the Sparrow Hawk, but differently colored. Above, excepting tail, 

 dark plumbeous, with a blackish collar below neck. Beneath, deep reddish, with a tinging of plumbeous 

 across breast. Throat, grayish white. The inner webs of the primaries arc slaty with transverse cloudino-s 

 . of darker. The female differs from that of the Sparrow Hawk in being dark rufous below and in havinc 

 •dusky mottlings on the inner webs of the primaries. Excepting as above, both sexes resemble the American 

 Sparrow Hawk. 



OBSERVATIONS. 



Known at once by the unhanded colors of both surfaces. Occurs in Cuba and Southern Florida. 



Note on Pigeon Hawk. In May, 1893, a nest of this species was obtained in a hole of a stub of an 

 apple tree near my place in Newtonville, Mass. The female was caught on the nest and with the cgs was 

 brought to me for identification. The tree in which this nest was found stood within two or three hundred 

 yards of an inhabited house. It was a low stub and the hole from which the eggs were taken was not over 

 ten feet from the ground. There were four of them, and they, with the female, are now in the collection of 

 Mr. E. W. Parker, of this place. 



A nest obtained by one of my collectors in the Magdalen Islands a few years ago was built of sticks and 

 placed in a tree. This contained four eggs, which are in the collectira of Mr Wm. Brewster, of Cambrid"e.
