Reported from all the islands except San Nicolas. This subspecies was first 

 described by C. H. Townsend (,9) from a male taken on San Clemente, January 

 25, 1889. From lutescens it differs in being darker, with larger feet and bill, and 

 slightly shorter wings. 



On the Coronados I have found the Dusky Warbler common, frequenting 

 mostly the denser growth of bushes on the hillsides. On May 27, 1914, D. R. 

 Dickey (MS) found four nests in a certain kind of scrubby bush, the lower or 

 downhill sides of which are always grown with gray moss. All four nests were 

 situated in clumps of this, but were empty. 



Common on the eastern part of San Clemente, where O. W. Howard (20) 

 found several sets of eggs in April, and young ready to leave the nest the first 

 Aveek in May. On the western end of the island, however, the species is almost 

 lacking, as two or possibly three birds were all that three of us heard or saw 

 during a three week's stay in the early spring of 1915. 



On Catalina I have found it rather abundant in the darker canyons and on 

 the wooded hillsides. In April, 1907 and 1908, I discovered several nests with 

 eggs or newly hatched young, but in the same month of 1911, although I found 

 the birds to be unusually common, they showed no indications of building, and a 

 diligent search for a week failed to reveal a single nest. Here during the last of 

 December, 1897, J. Grinnell (ii) says that they were feeding on the fruit of the 

 opuntia, which had stained their digestive organs and the surrounding tissue a 

 liright red. 



Reported provisionally from Santa Barbara Island by J. G. Cooper (i), 

 but its occurrence there has not been confirmed, and he may have been mistaken 

 in the birds he saw. On Anacapa, however, it occui^s in limited numbers, and H. 

 J. Iieland(> (35) took a set of four slightly incubated eggs there x\pril 6, 1906.
