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 liottoms. 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, T. h. ncsophilus was described by H. C. Oberholser {13) 

 from a bird taken on Santa Cruz Island by C. H. Townsend, February 7, 1889. 

 From charientnrus 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 cliari&nturus 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 

 occurs. 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, 1011, A. van Rossem and I found a nest containing half 

 groAvn young among the rafters of a small shack.

Abundant resident of San Clemente Island. Originally described 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, frecpienting 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
