A Focus on the Peregrine Falcon


Our on-going Peregrine Falcon research in the San Francisco Bay Area, fueled by a dedicated group of student and volunteer falcon observers, is revealing interesting nest location choices and dispersal patterns for hatch-year birds. These open modern challenges, as falcons have move beyond their traditional cliff nesting habitats to tall city buildings and bridges, so we advise owners of structures where Peregrine falcons nest how to accommodate these fully protected birds.

Banding in the Wild


Formed in 1975, the UC Santa Cruz Predatory Bird Research Group worked under state and federal permits along with cooperation from the Pacific States Peregrine Falcon Recovery Team to save the Peregrine Falcon from the brink of extinction. Our pioneering work led to the bird’s removal from the federal list of endangered species in 1999 and from California’s list of endangered species in 2009.

The Santa Cruz Predatory Bird Research Group also led or initiated successful breeding and release efforts for elf owls, Aplomado Falcons, Harris’s Hawks, and Bald Eagles. We also undertook significant studies of Prairie Falcons, Bald Eagle migrations, Goshawks, and Golden Eagles. In all, more than forty years of conservation biology have been funded primarily by private sector gifts and grants and supported by a robust volunteer effort.
