IGO NOTES OX JALIFOKNIA ANIMALS. 



The first is cliaiacterizeil by ii heavy growth of redwood forest, which 

 (h^es not extend much farther soutli in California than the Russian 

 lliver, and by a greater rainfall than any other part of the State. It 

 is apparently but a narrow southward extension of the redwood region 

 occupying the coast farther north, and with a similar climate. Several 

 species of birds are here found darker, or otherwise differentiated, 

 when couipared with examples from drier regions. Examples of such 

 ;(ri' the Valley Quail, the AVreu-Tit, and the California Jay, and they 

 have been distinguished from those on the opposite side of the mount- 

 ains as subsi)ecies. 



The second is the narrow northward extension of the great interior 

 l»laiu of California drained by the Sacramento lliver. It is compara- 

 tively dry and is usually unwooded, except in the vicinity of streams. 



The Magi)ie, tliu Koad-liunner, the Burrowing Owl, «&c., range from 

 the far south to the very head of the valley. The Antelope once 

 abounded here and the Badger finds here the open plains it requires. 



But the tliinl, or eastern, region, is the most nunked and the most 

 diversified. Beginning at the Xevada boundary line Avith level plains, 

 it rises through scattered hills to the li'gli Sierras. There are no large 

 streams, but large and small lakes are scattered everywhere, aiul open, 

 sage-covered meadows are fouud at random auu^ng the lower pine 

 forests. Birds of the central region of the United States, such as the 

 Sharp-tailed Grouse, Sage lien, and J^uttall's Whippoorwill, find the 

 Sierra XcN'adas an impassable barrier, and are found no farther west 

 in tliis latitude. The western limit of many mammals, among whicli 

 nmy be mentioned the Muh; Drerand tlie llocky Mountain Woodcliuck, 

 is also found here. 



In addition to the interest wliicli attaches to the meeting in Northern 

 California of the faunas of three se[)arate regions there is that of the 

 classitication of tlie country into tliree regions according to elevation: 

 The valleys or plains, but little above tlie level; the foot-hills or cliapar- 

 ral belt; and the i)iue forests extendiug from about o.OOO feet up to the 

 highest limit of timber. As might be ex])ectcd, these regions differ 

 greatly from ea(;h other in climate and vegetation.
