Indicator Species

The peregrine falcon is an important indicator species. Its carefully recorded population trends can be instructive about ecosystem health. We closely monitor the occupancy and productivity of peregrine falcons at approximately twenty-five nests in our Greater San Francisco Bay study area, and we band nestlings at a sample of those sites to learn more about the longevity, nest site tenacity, and juvenile dispersal patterns of Central California peregrine falcons. Citizen scientists around the bay report sightings of banded falcons.
