the cliffs. These are sometimes also built in the wind-blown trees near the preci- 
pices. 
I have seen eagles about Santa Barbara Island, as have others, but as the 
island is rather small, I think it probable that there is but one resident pair. Sev- 
eral pairs are resident on Anacapa, and it is interesting to note, as H. C. Burt 
(17) remarks, that all the sticks which enter into the construction of nests on 
this island, must laboriously be carried across five miles of sea from Santa Cruz 
Island. On the latter island they are said to kill lambs occasionally, and so are 
undoubtedly shot by the herders at every opportunity. A. van Rossem and I 
(18) found that most of the birds nested on the sea cliffs, but one nest was found 
in a large tree, well back in a canyon. This nest, on May 2, 1911, held a single 
young the size of a hen. 
The Bald Eagle occurs on San Miguel and undoubtedly on Santa Rosa as 
well. : 
The majority would seem to lay the first part of February, but fresh eggs 
may be found until late March.

from San Miguel, but no one else has since found it.

Common resident of all the islands. At least three and probably four pairs 
of these birds breed on the Coronados. During late March and early April, 1915, 
on San Clemente, I repeatedly saw a pair, but was unable to locate their nesting 
site. G. Willett (13) took a set of four eggs on Catalina, April 8, 1904, and I 
have observed several of the birds on the northwest part of the island. I flushed 
a pair from the cliff on the seaward side of Santa Barbara Island, where they 
undoubtedly had a nest of young, May 1, 1908, and H. C. Burt (72) noted a pair 
on Anaeapa. On Santa Cruz, O. W. Howard (13) collected a set April 5, 1906,
