Common resident of the Santa Barbara group. J. Grinnell and F. S. Dag- 

 gett {11) saw an eagle on the Coronados, August 6, 1902, and were told that i\ 

 pair of them had a nest. One of these birds was later killed, and during my sev- 

 eral visits since 1910 I have never seen one. 



D. R. Dickey, L. M. Huey and I found them nunierous on San Clemente in 

 the spring of 1915, and a pair that occupied an accessible nest still had eggs 

 April 3. C. B. Linton {15) says that scattered about the base of the cliffs Avhere 

 the nests were situated, were numerous skeletons of sheep and young lambs, but 

 Mr. Howland told us that during fifteen years of almost continued residence on 

 the island, lie had never seen an eagle carrying a lamb but once, and that was one 

 that had died a natural death. He was quite sure that they did not molest the 

 sheep at all. Worked into the material tliat formed the above nest found by ]\Ir. 

 Dickey, was the dessicated remains of a whole fox. 



Eagles are reported as abundant on San Nicolas, and J. G. Cooper {2) states 

 that on July 9, in the sixties, he saw more than thirty birds in immature plumage 

 soaring about the north end of Catalina. A number are killed here annually by 

 tourists and sheepherders, until now they are not quite so abundant. Still, sev- 

 eral individuals may be seen at almost any time, and many of their nests are on
