98 PACIFIC COAST AVIFAUNA No. 12 
In habits the Catalina wren is very similar to that of the mainland, being 
met with in the dry, heavy brush and in the wooded canyon bottoms. The birds 
prefer to breed in the latter places, selecting a knot hole or crack in a tree trunk, 
and in such a situation, on April 11, 1911, I found a nest which held one fresh 
egg. The species has been ascribed to Santa Barbara and San Nicolas islands by 
J. G. Cooper (1), but no one has since reported it from either place. 
Another subspecies, 7’. b. nesophilus was deseribed by H. C. Oberholser (13) 
from a bird taken on Santa Cruz Island by C. H. Townsend, February 7, 1889. 
From charienturus it is said to differ in being darker and more rufescent above, 
and from spilurus in being lighter and grayer with a longer bill. H. S. Swarth 
(35) states that he finds birds from Santa Cruz Island most nearly like charien- 
turus, and that the difference is very slight indeed, specimens being practically 
indistinguishable from birds that occupy the intermediate coastal region between 
the ranges of charienturus and spilurus. It is inferred that this applies also to 
the wrens of Santa Rosa Island. 
On Santa Cruz these wrens may be met with wherever fairly dense brush 
oceurs. J. Mailliard (4) states that they have but one song, sounding different 
from that of their mainland cousins, who have several. In this locality during 
the latter part of April, 1911, A. van Rossem and I found a nest containing half 
grown young among the rafters of a small shack.

Abundant resident of San Clemente Island. Originally deseribed by A. W. 
Anthony (4). Differs from charienturus in coloration being grayer, under tail 
coverts less heavily barred, and wing and bill decidedly longer. These wrens are 
evenly distributed over San Clemente, frequenting the densest thorn bushes and 
cactus patches, from the tops of which their loud clear song, differing but little 
from that of the mainland bird, is given. Before one is within good range of 
them they will casually hop down into the lower cactus, and it is very hard indeed
