are California species and do not occur in Sioux county. The Acadian and alder 
flycatcher are eastern forms that are found there. 
The form of the horned lark as would be supposed is different in the two 
sections, the desert horned lark being the common form in Sioux county and the 
Mexican horned lark in Santa Cruz. 
The yellow-billed magpie of California has much the same habits as its eastern 
relative the black-billed, but it is not so abundant and consequently seems much 
wilder. Instead of the harsh call of the California jay or the rattle of the coastjay, 
in Sioux county the more musical croak of the pinyoii jay is heard, while an oc- 
casional eastern blue jay is to be seen endeavoring to make the other birds know 
that he is there to jolly up the hawks and owls. Once in a while a Clarke crow 
may be seen perched on the top of some tall pine. Rarely also the common crow 
will be seen winging its way across the canyon in search of better feeding grounds, 
and although it is quite uncommon in the Pajaro valley, it is more abundant than 
in Sioux county. That bird parasite, the cowbird, is common in Sioux county, 
and fortunately for the other birds it is not so in California. The bronzed grackle 
is an eastern bird without a California relative, but the red-wing of the east is re- 
presented by tlie bicolored black-bird. 
The family Fringillidae is largely represented by different species in the two 
localities. The Santa Cruz birds are the purple finch, linnet, Arkansas goldfinch, 
intermediate, Nuttall, and golden-crowned sparrows, Point Pinos junco, Santa Cruz 
song sparrow, California, and spurred towhees. The Sioux county species are the 
American goldfinch, McCowni longspur, western vesper, Baird, and w'estern grass- 
hopper sparrows, white-winged junco, mountain song sparrow, Arctic towhee, 
dickcissel, and the lark bunting. It is likely that the intermediate, and 
golden-crowned sparrows occur in Sioux county during their migrations as they 
are common further east. 
The warblers and vireos are well represented in the two sections; the western 
warbling vireo, Pacific j'ellow-throat, and the Calaveras, Townsend, pileolated, and 
black-throated gray warblers are Santa Cruz species, while the plumbeous, and red- 
eyed vireos, the western yellowy-throat and the Tennessee, and yellow-rumped 
warblers, and the redstart are Sioux county forms. One of the most interesting 
variations in the warblers is the fact that the Audubon warbler which is so com- 
mon a winter resident in the Pajaro valley is a rather common breeder in 
Sioux county. 
The remaining birds that w^ere found in Santa Cruz county were the western 
martin, California shrike, American pipit, California thrasher, the Vigors, western 
winter, and tule wrens, California creeper, plain-tit, Barlow chickadee, intermed- 
iate wren-tit, bush tit, ruby-crowned kinglet, western gnatcatcher, hermit thrush, 
varied thrush, and the western bluebird. Those in Sioux county are the white- 
rumped shrike, brown thrasher, catbird, western house wren, slender-billed nut- 
hatch, Townsend solitaire, wood thrush, eastern robin, eastern bluebird and the 
mountain bluebird. 
The best singers of both regions are found in these last two bunches. Perhaps 
the best California one is the California thrasher but I do not think that it equals 
either the brown thrasher, the catbird, or the Townsend’ solitaire which are all 
rather common in the Nebraska region.
