Rather common resident of Santa Cruz, and present on Catalina during the 

 winter at least. J. Grinnell (i) met with these birds in some numbers on Cata- 

 lina during December, 1897, flushing them from the north slopes, where they 

 were digging in the damp turf for larvae. I have noted two or three here in 

 early April. C. H. Richardson (8) considers them to be merely winter visitants 

 in this locality, as he was unable to find any old nesting holes. H. Linton (MS) 

 shot one on San Nicolas in May, 1910, which he presented to G. Willett. 



Numerous on Santa Cruz, and although no nests have been reported, they 

 surely breed as they are present throughout the year. A. van Rossem and I 

 found them exceedingly shy. We stated (10, 13) that many birds were seen in 

 which the usual red was replaced by yellow, and judged accordingly that there 

 were also Northern Flickers present, or at least hybrids which closely approached 

 the latter. I have since changed this opinion, and consider, that whatever may 

 be the correct explanation of the occurrence of the so-called hybrid flickers that 

 are reported from many parts of the west, the birds of Santa Cruz are amenable 

 to the same influences that cause the red of the linnets here often to be replaced 

 by yellow.

A regular but not common migrant through the southern islands. J. Grin- 

 nell (1) says that on San Clemente from March 30 to April 2, 1897, this bird 

 was heard each evening, and a female was secured March 31. As no one else has 

 heard them there, the above would indicate that perhaps there was an unusually 

 heavy migratory wave of them passing through that year. C. H. Richardson (3) 

 has seen them occasionally in April on Catalina, and during 1911 I saw two birds 

 on the 8th of that month and another on the 10th. 0. W. Howard (MS) shot a 

 bird on Anacapa Island,' April 6, 1906.

G. Willett (1) shot an adult female on Santa Barbara Island, June 20, 1911, 

 and dissection showed her to be breeding. Although a careful search was made 

 during the succeeding days, her mate could not be located, and it is barely possi- 

 ble that she liad wandered over from one of the larger islands the night before.
