ARIZONA JAY 



The Arizona Jay (Aphelocoma sieherii arizofKB) is a subspecies of Sieber's 

 Jay, of which there are several subspecies in Mexico, but of which only the 

 present and following form occur in the United States. The Arizona Jay is 

 practically resident wherever found, and ranges from southeastern Arizona 

 and southwestern New Mexico south to northeastern Sonora and northern 

 Chihuahua. 



COUCH'S JAY 



Couch's Jay {Aphelocoma sieberii couchii) is the other United States race of 

 Sieber's Jay, and ranges from southern Nuevo Leon northwest through the 

 Mexican state of Coahuila to just over the United States boundary in the Chisos 

 Mountains of central western Texas. 



FLORIDA JAY 



The Florida Jay {Aphelocoma cyanea) is resident, locally, in the peninsula 

 of Florida, where it inhabits the low scrub south to Fort Myers and Miami 

 and north to Jacksonville. 



CALIFORNIA JAY 



The California Jay {Aphelocoma calif ornica) as a species now includes as 

 subspecies several forms of the genus Aphelocoma that were formerly considered 

 species. It thus has a rather wide geographic range from Washington and 

 Idaho south to southern Mexico, and from the Pacific coast east to Wyoming and 

 Texas. All its races, like all the other representatives of the genus, are 

 strictly resident, and we have, therefore, no migration dates to offer. 



The typical California Jay {Aphelocoma californica californica) occurs in 

 the coast district of central western California, east to the Coast Ranges, north 

 to the southern side of San Francisco Bay, and south to Santa Barbara and 

 Ventura counties. 



Swarth's Jay {Aphelocoma californica oocleptica) inhabits the coast region 

 of northern California, east to the Coast Ranges, south to San Francisco Bay, 

 and north to Wedderburn, southwestern Oregon. 



The Long-Tailed Jay {Aphelocoma californica immanis) is confined chiefly 

 to California and Oregon, ranging north to central southern Oregon and 

 southwestern Washington, west to the Coast Ranges of Oregon and northern 

 California, south to the southern Sierra Nevada and south central California,
