2^4 Grinnell, Wiiiter Birds of Santa Catalina Is., L. Cal. Ljuly 



Birds were most numerous in the larger canons, especially where 

 there was any water. The majority of birds in point of numbers 

 were winter visitants. Out of the 29 species identified, 14 are 

 known to me to be resident on this island. They are : CalUpepIa 

 californica valUcoIa^ Zenaidiira macroura, Buteo borealis calurus, 

 Haliceetus leucocephalus, Selasphorus alleni, Sayorfiis nigricans^ 

 Corvus corax sinuatus^ Carpodaciis viexicanus frontalis^ Pipilo 

 fjiaculatus megalonyx^ Lanius ludovicianus gajnbeli, Salpinctes obso- 

 letiis, Hebninthophila celata sordida, Mimus polyglotios, and Thryo- 

 thorus bewickii spilurus. 



I was surprised not to find several birds which are numerous 

 on San Clemente Island, for Catalina lies almost exactly between 

 that island and the mainland. Song Sparrows and Horned Larks 

 were remarkable by their apparent absence from Catalina, and 

 besides these, the Chipping Sparrow, Meadowlark and Bell's Spar- 

 row were not discovered. Horned Larks and Song Sparrows are 

 also abundant on Santa Barbara Island which lies about 20 miles 

 northwest of Catalina. The following is a briefly annotated list 

 of the birds detected on Santa Catalina Island during my Decem- 

 ber visit. 



Callipepla californica vallicola. Valley Partridge. — Verj abundant 

 in the brushy canons. The 'Quail' is not native on the island, but was 

 originally introduced from the mainland. 



Zenaidura macroura. Mourning Dove. — I saw several pairs among 

 the hill-tops toward the interior of the island. 



Buteo borealis calurus. Western Red-tail. — Scarcely a day passed 

 but what two or three of these large Hawks were seen circling among the 

 hills. An immature specimen in very dark plumage was brought in by 

 a local hunter. 



Haliaeetus leucocephalus. Bald Eagle. — Common along the pre- 

 cipitous margins of the island. 



Asio accipitrinus. Short-eared Owl. — I examined a newly-mounted 

 specimen in a taxidermist's shop at Avalon ; it had been shot about a 

 week before. 



Speotyto cunicularia hypogaea. Burrowing Owl.— I saw a single 

 individual on a hill-top in the interior. I was told that this Owl becomes 

 quite numerous at times. 



Ceryle alcyon. Belted Kingfisher. — Tolerably common along 

 rocky shores. 



Colap'tes cafer. Bed-shafted Flicker. — Tolerably common, being
