1917 BIRDS OF THE SOUTHERN CALIFORNIA ISLANDS 83 



How many broods each season they may raise I do not know, ])ut there must be 

 three at least. Their notes are very similar to those of the mainland birds. 



G. Willett (26) reports that in June, 1910, this was one of the commonest 

 birds on San IMigiiel, and several writers have recorded it as present on Santa 

 Rosa Island in considerable numbers. Just why gratninea should occur in the 

 intermediate territory between the extreme ranges of clementae, with climatic 

 and food conditions apparently very similar, is a problem in distribution on 

 which I am able to throw no light.

Evidently a rather rare but regular winter visitant. J. Grinnell {!) took 

 one bird and saw another on San Clemente, March 30, 1897. He (,2) also saw 

 one on two occasions in a dooryard on Catalina in December, 1897, and there 

 was an adult female taken here by C. P. Streator (J) during April, 1892. Col- 

 lected also by J. Mailliard (i) in April, 1898, on Santa Cruz Island.

During the winter months fox sparrows occur on the islands in consider- 

 able numbers, but as they have been reported so often on sight identification 

 alone, it is hard to judge the relative numbers of the several forms. 



C. B. Linton (2) took a female of the subspecies unalaschcensis on San Cle- 

 mente Island, November 21, 1908, pronounced by J. Grinnell as not typical. A. 

 van Rossem shot one on Santa Cruz, April 27, 1911, and I saw another which 

 may or may not have been of this form.

On Catalina, during late December, 1897, J. Grinnell (1) took four speci- 

 mens referable to this race; C. P. Streator (2) shot three typical ones in April, 

 1892, and A. van Rossem (.5) secured a pair February 15, 1910. I shot a female 

 on San Clemente, March 28, 1915. On the day before I had seen a bird which 

 appeared to be of the same subspecies. G. Willett (.5) collected an adult female
