Violet-green Swallow- Nests in coastal and Interior foothills, not on valley floor; <br /> probably a migrant species. <br /> Cliff Swallow- We saw no evidence of nesting colonies on the site, and suspect <br /> that they do not nest there. Colonies are usually under bridges with the nearest <br /> colonies on overpasses along Hwy. 99. <br /> Hermit Thrush -Winters on valley floor, breeds north to Canada, and In high <br /> Sierra. <br /> D86 <br /> California Thrasher - The presence of this species seems unlikely, except as a <br /> extrallmital wanderer during winter months. The area has limited habitat to <br /> support nesting California Thrashers. <br /> Yellow-romped Warbler- A winter visitor to the valley, nests in montane regions <br /> of the west, not in valley in summer. <br /> Warbling Vireo -A migrant species. Once breed in Sacramento Valley, but has <br /> been extirpated. The presence of this species as a nester seems highly unlikely. <br /> Orange-crowned Warbler- We are not sure what a migrant breeder Is. The <br /> species may be present as a resident, but is most likely a winter visitor and <br /> migrant. Confirmation of nesting would be required. <br /> Western Tanager- Not sure what is meant by the status"OB?" The species is a <br /> migrant through the valley, but nests in montane regions of California <br /> Northam Oriole - A neotropical migrant, nesting during the summer months, not a <br /> resident. <br /> Chipping Sparrow- A broader of montane habitats, present as a spring migrant in <br /> the valley. <br /> Dark-eyed Junco - A winter visitor not nesting in the valley. <br /> REFERENCES <br /> Barbour, M.
