Sponsored by Friends of Griffith Park, the Los Angeles Raptor Study engages volunteers all across Los Angeles to monitor raptor nests (hawks, owls, and falcons) during spring and summer to learn how these birds are adapting to the urban environment.
The study was first launched in 2017 as Griffith Park Raptor Survey and has expanded since then. Each year, trained volunteers record observations at dozens of raptor nests located in parks, schools, and yards across the city and surrounding communities. This data-gathering is vital to biologists because it represents a specific, comprehensive dataset of raptor habits over multiple years.
Get Involved!
A community-science based program, the LA Raptor Study relies on volunteers. Early in the year, the leadership team provides volunteers with free training sessions to learn the types of raptors found in the LA area, how to track nest activity and how to record observations.
Volunteers are asked to commit to monitoring their nests at least twice a month and report the data regularly to one of the study coordinators.
If you are interested in volunteering for the study, please fill out this volunteer application. If you have questions about volunteering contact griffithparkraptors@gmail.com
Yearly Monitoring Schedule:
- Late January/early February: Volunteer training, led by biologists Dan Cooper and Courtney McCammon; nest-searching, including re-visiting known nest sites.
- March: Volunteers are deployed to monitor their assigned nests with individualized orientation by one of four study coordinators. If new nests are located, basic data is recorded on substrate/tree species, topography, GPS coordinates, and more.
- April-June: Volunteers continue to monitor nesting activity stages, such as egg incubation, chicks, and finally fledging, as birds leave the nest by the end of June.
- July-August: Volunteer party; data analysis and results presentation.

Daniel S. Cooper
Study Director
Bio
Daniel S. Cooper is principal investigator and scientific advisor for Friends of Griffith Park. Dan grew up in Pasadena with a passion for birds and nature. His academic credentials include: Harvard University, U.C. Riverside (MS), and UCLA Ecology and Evolutionary Biology (PhD). He is president of Cooper Ecological Monitoring.
As one of California’s leading ornithologists, Dan published Important Bird Areas of California and has a list of scientific publications to his credit. He has served several functions for California Audubon, including Director of Bird Conservation.
Beginning in late 2006, Dan became the lead ecologist conducting surveys under the umbrella Griffith Park Natural History Survey. After the 2007 park fire, Dan advised the Department of Recreation and Parks on fire recovery and was commissioned to write the Griffith Park Wildlife Management Plan. Highlights of his professional contributions to Griffith Park science include the Griffith Park Rare Plant Survey and the continuing Griffith Park Raptor Survey, both highly successful endeavors underwritten by FoGP.

Gerry Hans
President, Friends of Griffith Park
Bio
For well over fifteen years, Gerry Hans has been active with park issues and was a diligent member of the Griffith Park Master Plan Working Group which convened in 2005. He served as president of Oaks Homeowners for three years (2005-2007) and fought for the City’s toughest anti-mansionization code to protect the community’s unique character with plenty of open space. Gerry also played a role in establishing invaluable scientific work for the park beginning in late 2006 through the Griffith Park Natural History Survey. He served on the Parks, River and Open Space Committee of the local neighborhood council until 2010, and is currently active with the county-wide helicopter noise reduction movement.
Gerry comes from a large Midwest farm family of ten and holds a Biology degree from University of Illinois. He began graduate work at Colorado State in ecology, but was side-tracked by corporate positions, moving to Los Angeles 34 years ago. After leaving the corporate world, he and his spouse built a successful small business, from which he is now retired.
As a founding member of Friends of Griffith Park and its inaugural president, Gerry keeps busy tracking the organization’s progress with advocacy issues, including the revitalization of historic Fern Dell. He enjoys hiking and “botanizing” in Griffith Park, while thinking about ways to protect the park’s rich Mediterranean habitat and wildlife, in balance with recreation.
Gerry has been closely engaged with the science and conservation aspects within Griffith Park, and recently coordinated successful efforts with other conservationists to purchase and protect acreage adjacent to the Park.
