1917 BIRDS OF THE SOUTHERN CALIFORNIA ISLANDS .V, 



The C'atalina quail was separated by J. Grinnell {10), the type being a bird 

 collected November 25, 1904. He says that it is about nine per cent larger than 

 vnlUroJa, and darker and more l)rovvnish dorsally tlian ealifoniica. Tail longer, 

 bill heavier, toes and tarsus stouter, than in eitlicr inainhind i-ace. It was not 

 accepted l)y tlie A. 0. V. Coinmittee (ii), but all tiic l)ir(ls wliicli I liave neon 

 could be easily told from eithei' of the mainland forms, and T believe it to be a 

 good subspecies. They are a])undant on the island. A lialf finished nest found 

 by C. IT. Richardson (12) in April, 1907, differed in no manner from tliat of 

 mainland vallicola. 



II. W. Henshaw (3) states that quail were at OU'' time introduced on Santa 

 C'l'uz Island, but as none have been taken there as far as I know, tliey have prob- 

 ably disappeared, and there is no way of knowing whether they were califor)nc<i 

 or vallicola.

Rather common resident of certain of the islands. J. Grinnell (5) found 

 this bird quite numerous near tbe lower end of San Clemente during the spring 

 of 1897. Twenty or thirty of them roosted in a small elunip 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. II. 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. Here H. Wright (12) found 

 a nest containing a single (^^g, July 7, 1912.
