38 PACIFIC COAST AVIFAUNA No. 12 
The nests of albociliatus can always be told at a glance from those of the 
two following species. They are quite bulky and well made, and are invariably 
formed of weed stems, small sticks, or whatever similar material is handy. They 
are always placed (on these islands) on the ground, usually on a high hillside. 
Although breeding in colonies, these are seldom compact ones, and where a peli- 
ean colony is available, they prefer to build among the nests of the latter. Three, 
more rarely four, and occasionally five, eggs are laid, but because of the depre- 
dations of the gulls the breeding season is a long one. In addition, the time when 
eggs are deposited would seem to vary greatly from year to year (as is the case 
with our other cormorants as well), for A. van Rossem (MS) took a set of five 
eggs on the Coronados March 26, 1909, while J. Grinnell and F. 8. Daggett (73) 
found two nests with eggs, and several containing small young, in the same loeal- 
ity, August 7, 1902.

This, our commonest species of the genus, is to be found about the shores 
of all the islands and the adjacent mainland, breeding on or near all the islands 
that have suitable rocky promontories. There are perhaps a dozen colonies of 
these birds on the Coronados, distributed over all four of the islands. J. Grin- 
nell and F. S. Daggett (12) found that they had completed nesting operations 
for the year there by August 7, 1902. ; 
©. B. Linton (15) noted immense flocks on San Clemente during January 
and February, 1907. These flew back and forth daily, between their roosts on 
the northwest coast and the feeding grounds, and I observed the same thing there 
the first part of April, 1915. Linton took specimens in breeding plumage in Feb- 
ruary and March, and reported the species as breeding in small numbers on the 
northwest coast of the island. 
J. Grinnell (7) states that there is a small colony on the north side of San 
Nicolas Island, and C. B. Linton (27) saw incomplete sets there April 3, 1910. 
They breed in limited numbers on several large detached rocks near Catalina. 
There are large rookeries on Santa Barbara Island, where I found fresh eggs
