<br />Ing~ortant Wintering Passerine Species. The white-crowned sparrow was the rrost <br />abundant species encountered during 'the winter passerine surveys, averaging . <br />14.3 individuals/icn over all transacts. This species was observed in the <br />alfalfa field, juniper and~ripari..an habitats and exhibited a definite affinity <br />for the riparian type. FfiiYE-ero4med sparrows are usually found in thickets <br />adjacent to fields or open areas (Robbins et al. 1966). <br />The 7regon junco was the secrond frost abundant species observed averaging <br />8.0 individuals/)mi over all transacts. The Oregon junco was observed in the <br />juniper and riparian types and exhibitrxl an affinity for the riparian type. <br />This species is usually abundant in coniferous forests; however, in winter <br />the Oregon junco is eamnn in farmyards and fields U~obbins et al. 1966). <br />The third most abundant species observed was the western :resdaalark averaging <br />7.1 individuals/lan over all transacts. However, this species was observed only <br />in the alfalfa field habitat, where it was the most abundant species observed <br />(35.3 individuals/Jan). The western meadixalark is a year-round resiaent of <br />• ~ the study area. .- <br />Although ttve raven was not fourui in high numbers in any habitat type, it did , <br />have a widespread distribution almng habitats on the study area. It was found <br />in all types sanq~led and as a result of the iow 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 ware conducted during all wildlife studies to ax~q~ile a Mete list <br />of birds occupying the study site. Passerine species observed during these <br />qualitative surveys but not encountered on transacts were: rock wren, western <br />kingbird, and yellow warbler. These passerines were sighted during the summer <br />qualitative surveys. The western kingbirds are m~nuonly 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 grave of trees at the <br />farmstead on the study area. <br />~- Pock wrens are canron in rocky areas. One rock wren was observed in the pin- <br />. -36- <br />• <br />JUM 1 1 1980 <br />(Revised August 2006) Attachment 2.04.10-10-43 <br />
