Reported from all the islands exeept 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 (JS) found four nests in a certain kind of serubby 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 
week 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 (14) says that they were feeding on the fruit of the 
opuntia, which had stained their digestive organs and the surrounding tissue a 
bright red. 
Reported provisionally from Santa Barbara Island by J. G. Cooper (1), 
but its occurrence there has not been confirmed, and he may have been mistaken 
in the birds he saw. On Anacapa, however, it ocewrs in limited numbers, and H. 
J. Lelande (35) took a set of four slightly ineubated eggs there April 6, 1906.
