A Focus on the Peregrine Falcon


We are an affiliated research group at the University of California Santa Cruz. Our on-going Peregrine Falcon research in the San Francisco Bay Area is revealing interesting nest location choices and dispersal patterns for hatch year birds. Today, we advise owners of structures where Peregrine Falcons nest how to accommodate these fully protected birds, and lead a dedicated group of student and volunteer falcon observers. See a description of recent work here.


The UC Santa Cruz Predatory Bird Research Group was formed in 1975. State and federal permits, along with cooperation from the Pacific States Peregrine Falcon Recovery Team, made possible pioneering work at the University that led to the bird’s removal from the federal list of endangered species in 1999, and California’s list of endangered species in 2009.

The Santa Cruz Predatory Bird Research Group also led or initiated successful efforts to breed and/or release Elf Owls, Aplomado Falcons, Harris’ Hawks, and Bald Eagles. Significant studies of Prairie Falcons, Bald Eagle migrations, Goshawks, and Golden Eagles were undertaken. More than forty years of conservation biology have been funded primarily by private sector gifts and grants, and supported by a robust volunteer effort.
