Description

The primary goal of this study was to determine the historical baseline (i.e., before rapid climate change) of breeding phenology for resident and migratory birds in California. The researchers draw on data from three museums and find that seven of 21 species examined had significant trends in laying date, with some species laying eggs earlier and others later. The largest changes were in the oak titmouse with an average shift of 20 days later per decade and phainopepla with the largest earlier shift of 8 days earlier per decade. This is a state-funded research study sponsored by the California Energy Commission.
