Breeding Birds
This Central Valley Bird Club special publication compares the results of two Breeding Bird Atlases for Sacramento County conducted nearly 30 years apart. The comparison reveals changes in breeding bird status and distribution in the context of a warming climate and dramatic changes in land use. It focuses on the most significant changes with chapters on changes in land use and climate, new and lost breeders, and species showing significant changes in range or habitat use. The results for every species are displayed on individual pages with maps and charts. The changes are also put into the perspective of regional and rangewide trends. We have also made all the raw data available for download for anyone looking to use these data in their research.
