LA Raptor Study

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

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.
