BIRDS OF JACKSON CO., OREGON, & SURROUNDING AREAS 19 



Species restricted to the Chaparral-Oak Community, Lower Rogue 

 Valley are the following: 



California Quail Long-billed Marsh Wren 



Ring-necked Pheasant *Rock Wren 



Virginia Rail Blue-gray Gnatcatcher 



Sora Yellow-breasted Chat 



Poor-will Yellow-headed Blackbird 



*Acorn Woodpecker Tricolored Blackbird 



Western Kingbird ^Northern Oriole 



Black Phoebe *Lazuli Bunting 



*Plain Titmouse Lesser Goldfinch 



Wren-tit Brown Towhee 



Black-chinned Sparrow Lark Sparrow 



The Sora and Black-chinned Sparrow possibly breed in the county, 

 and the Long-billed Marsh Wren probably breeds there. All other 

 ' pecies have been confirmed to breed in the county. 



Five of the above species (des'gnated *) also breed in the Chaparral- 

 Oak Community of extreme southeastern Jackson County. This part 

 of the county differs from the Lower Rogue River and Bear Creek 

 valleys in climate, elevation, and somewhat by dominant vegetation. 

 Average elevations are 610 m for the valley area and 914 m for the 

 southeastern part of the county. Climatic conditions are not specifi- 

 cally known for the southeastern part of the county, but mean tem- 

 perature is undoubtedly lower than in Medford and precipitation is 

 probably greater with more snow. Dominant plants in the southeast 

 include Quercus spp., Pinus ponderosa, and Ceonothus spp. 



Species restricted to Mixed Conifer Forest {Pinus dominated) are : 

 White-headed Woodpecker, Pygmy Nuthatch, and Green-tailed 

 Towhee. 



Species restricted to Mixed Conifer Forest (non-Pinus) are : Pygmy 

 Owl, Vaux's Swift, Winter Wren, and MacGillivray's Warbler. 



Species restricted to True Fir Forest are: Williamson's Sapsucker, 

 Black-backed Three-toed Woodpecker, Olive-sided Flycatcher, Gray 

 Jay, Hermit Warbler, and Cassin's Finch. 



Species restricted to Timberline Forest are: Northern Three-toed 

 Woodpecker and Clark's Nutcracker. 



All avian species found in the Siskiyou Mountains are found in the 

 Cascade Mountains. There are, however, seven species found in the 

 Cascade Mountains that are not found in the Siskiyou Mountains. 

 Gabrielson (1931:110) also mentioned similar differences. The differ- 

 ences in the avifauna between the Siskiyou and Cascade mountains are 

 not readily apparent. Waring (1969) considers the Siskiyou Mountains 

 to be poorly represented by mesophytes and Franklin and Dyrness
