By far the most impressive examples of these habitats are in the Sierra Valley (Plumas and Sierra Counties), where, in conjunction with marshlands and wet meadows, these habitats attract impressive numbers of waterfowl and wintering raptors, nesting Sandhill Cranes, shorebirds, and waterfowl. Orchards and Vineyards Compared to all-natural habitats, orchards and vineyards are relatively barren of breeding birds. In some parts of the Foothill zone, largescale conversion of annual grasslands, oak savannas, and oak woodlands to orchards and vineyards has resulted in direct losses of bird habitat.
Red Fir Forests North 6,500 to 8,500 feet; South 7,000 to 9,000 feet Red fir forests receive the heaviest Sierra snows. In these shady groves deep drifts often last long into summer, gradually releasing moisture into the soil. Small numbers of red firs grow on north slopes in the mixed conifer zone, but higher up their dark, silent columns reign supreme. Entire forests consist of only these trees, with rings of chartreuse lichen circling their trunks above the snow line. Often lodgepole and western white pines are mixed in, as are white firs at the lower edge of these forests.
The sapsuckers are occasionally found at lower elevations (even down to the Central Valley) very rarely, but the grosbeaks seem to simply vanish in winter. Hardy birders venturing into the high Sierra in winter, and very observant birders anywhere, could add much to our knowledge of the movements and winter whereabouts of these species. What are the exact range limits of the two Sierra subspecies of White-breasted Nuthatch? Do Black-backed Woodpeckers require recently burned forests? This species spills over onto the West Side here and there, especially in the northern Sierra.
