BREWSTER: BIRDS OF THE CAPE REGION, LOWER CALIFORNIA. 83 



soaked, its body very thin, indicating tliat it had been made desperate by 

 starvation. 



Mr. Belding has seen Harris's Hawk about forty miles south of San Diego, 

 California, and hence very near the northern bounchiry of the Peninsula. Mr. 

 Br}\ant has observed it at San Jorge, near San .Juan, and at San Gregoria. 

 At the place last named he found a nest on April 6, 1889, built in the top of a 

 bush (Atamisq^iea emarginata) and containing two eggs, " one of them quite 

 fresh, the other with a small embryo."^ 



Mr. Anthony states that a few birds of this species nested in 1894 near San 

 Fernando, " in cirios between the mine and the beach," ^ and that during the 

 previous year others were seen in valleys " between Ensenada and Colnett, 

 and in one or two places on San Pedro [Martir] as high as 7000 feet."^ 



The general range of Harris's Hawk on or near the Pacific coast extends 

 from northern Lower California to Panama.

The determination of the Red-tailed Hawks collected by Mr. Frazar in 

 Lower California has proved .somewhat difficult, for they vary exceedingly in 

 color and markings. In fact I found it impossible to come to any satisfactory 

 conclusion regarding them until, thanks to the kindness of Mr. Ridgway and 

 Dr. Allen, I was able to compare them with the material in the U. S. National 

 Museum and in the American Museum of New York. This includes the type 

 of Buteo borealis lucasanus as well as four other specimens referred to that 

 form by Mr. Ridgway ; three specimens each, including the tj-pes, of Buteo 

 borealis socorroensis and B. h. costaricensis ; and a superb series of B. b. calurus,
