1917 BIRDS OF THE SOUTHERN CALIFORNIA ISLANDS 
ue 
oe) 
The Catalina quail was separated by J. Grinnell (70), the type being a bird 
collected November 25, 1904. He says that it is about nine per cent larger than 
vallicola, and darker and more brownish dorsally than californica. Tail longer, 
bill heavier, toes and tarsus stouter, than in either mainland race. It was not 
aceepted by the A. O. U. Committee (74), but all the birds which I have seen 
could be easily told from either of the mainland forms, and I believe it to be a 
good subspecies. They are abundant on the island. A half finished nest found 
by C. H. Richardson (12) in April, 1907, differed in no manner from that of 
mainland vallicola. ? 
H. W. Henshaw (.3) states that quail were at one time introduced on Santa 
Cruz Island, but as none have been taken there as far as I know, they have prob- 
ably disappeared, and there is no way of knowing whether they were californica 
or vallicola.

Rather common resident of certain of the islands. J. Grinnell (5) found 
this bird quite numerous near the lower end of San Clemente during the spring 
of 1897. Twenty or thirty of them roosted in a small clump of cherry trees in a 
ravine, coming to it just at dusk. Two nests were found by him on June 3 and 6, 
respectively, both being situated on horizontal branches of wild cherry. In the 
treeless northern part of the island, however, they are distinctly rare, and I saw 
but a single individual during a three weeks stay in the spring of 1915. 
I have noted them in some numbers on Catalina, and C. H. Richardson (2) 
found that they pair in April there. J. Grinnell (5) saw about a dozen birds on 
San Nicolas in May, 1897, and remarks that a specimen secured is very much 
darker than any he had seen from the mainland. He also saw about the same 
number on Santa Barbara Island in May, 1897, but on the first of that month, 
1908, I could find but a single bird in the locality. This is such a small barren 
island that one feels surprised at meeting these birds. They, in addition to some 
of the other land birds, must get their supply of moisture from the ice plant 
which grows so abundantly. 
A. van Rossem and I found doves to be common on Santa Cruz the latter 
part of April, 1911, where they seemed partial to the upper edges of the bare 
grass lands, and to the borders of the little canyons. Tere H. Wright (72) found 
a nest containing a single egg, July 7, 1912.
