BIRDS OF LOWER CALIFORNIA. 279 



from Tia Juana to San Pedro Mavtir. Mr. Anthony found 

 them abundant along the coast and in open country, nesting 

 at Cape Colnett and San Ramon. They were not seen at an 

 altitude greater than about 2,500 feet. In Febraar}^, 1888, 

 I saw two on Magdalena Island and an immature specimen 

 was seen at lower Purisima caiion April 5, 1889. 



118. Accipiter velox (Wils.) 



Sharp-shinned Hawk. — Mr. Belding says it is rare at the 

 Cape region. Mr. Anthony gives it as resident of the region 

 north of San Fernando, ranging as high as 4,000 feet alti- 

 tude, and adds that this species, as well as A. cooperi, is very 

 destructive to quail. At San Juan, in March, 1888, I saw 

 one in pursuit of a small bird. One was seen on Santa 

 Margarita Island March 1, 1889. 



119. Accipiter cooperi (Bonap.) 



Cooper's Hawk. — Mr. Xantus collected this hawk at Cape 

 St. Lucas in October. Mr. Belding found it rare in the 

 vicinity of La Paz. Mr. Anthony found it comoion as high 

 as 4,000 feet altitude until late in the spring, and thinks he 

 has not seen it after the last of May. 



120. Parabuteo unicinctus harrisi (Aud.) 



Harris's Hawk. — Mr. Belding records it as common at 

 the Cape region where he frequently met with it in May 

 along the route from San Jose del Cabo to Miraflores. He 

 also found it within forty miles of San Diego, and shot a 

 specimen May 10, 1885. I first saw one at San Jorge, and 

 again near San Juan where a pair had built in a giant cac- 

 tus (Cereus). They were more often seen than red- tailed 

 hawks. On April 6, 1889, I found a nest at San Gregorio 

 built on the top of a bush (Atamisqitea emarginata) . The 

 nest was rather flat, composed of sticks and lined with grass 

 and '' orcMlla." It measured about two feet in diameter. 

 One of the birds was sitting and flew, when, standing on my 

 saddle, I raised my head to the height of the nest. Two eggs 

 were secured, one of them quite fresh, the other with a
