Common resident of the Santa Barbara group. J. Grinnell and F. 8S. Dag- 
gett (17) saw an eagle on the Coronados, August 6, 1902, and were told that a 
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. Diekey, L. M. Huey and I found them numerous 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 where 
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, he 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 that formed the above nest found by Mr. 
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
