.. _____ <br />• Ing~ortant Wintering Passerine Species. The white-crowned sparrow was the nest <br />abundant species encountered during the winter passerine surveys, averaging <br />14.3 individuals/lan over all transects, This species was observed in the <br />alfalfa field, juniper and riparian habitats and exhibited a definite affinity <br />for the riparian type. l~lnite-crowned sparrows are usually found in thickets <br />adjacent to fields or open areas (F~bbins et al. 1966). <br />The Oregon junco was the second most abundant species observed averaging <br />8.0 individuals/lrn~ over all transects. The Oregon junco was observed in the <br />juniper and riparian types and exhibited an affinity for the riparian type. <br />This species is usually abundant in coniferous forests; however, in winter <br />the Oregon junco is oormnn in farn~yards and fields (Fabbins et al. 1966). <br />The third rrost abundant species observed was the western meadowlark averaging <br />7.1 individuals/lan over all transects. I-Iwever, this species was observed only <br />in the alfalfa field habitat, where it was the most abundant species observed <br />• (35.3 individuals/lan). The western meadowlark is a year-round resident of <br />the study area. <br />Although the raven was not found in high numbexs in any habitat type, it did <br />have a widespread distribution arrong habitats on the study area. It was found <br />in all types sailed and as a result of the cow number of observations an <br />affinity for any one habitat was not apparent. <br />Qualitative Surveys. Qualitative surveys of areas not subjected to strip <br />census were conducted during all wildlife studies to compile a cong~lete list <br />of birds occupying the study site. Passerine species observed during these <br />qualitative surveys but not encountered on transects were: crock wren, western <br />kingbird, and yellow warbler. These passerines were sighted during the s~smier <br />qualitative surveys. The western kingbirds are oomronly found about farms <br />and along streams where scattered trees provide nesting opportunities. The <br />one western kingbird sighted on the study area was in a grove of trees at the <br />farmstead on the study area, <br />• Fick wrens are oomron in rocky areas. One rock wren was observed in the pin- <br />-36- <br />JuM i i ~9eo <br />
