The 2020 Raptor Survey is Again Gearing Up – Calling All Volunteers!


Maybe you had such a great time last year, you’re ready to participate again this year –or– time constraints prevented you from participating in the past and you now have free time to spend out in the field watching raptors fly… and make little raptors.

Either way, the Raptor Study is back for the fourth year and FoGP is excited to again be part of it. If you’re interested in participating, there will be two training sessions (attendance to one is required for all those wishing to participate). Volunteer application form pdf is included at bottom – you can fill it in and bring to the training session. A brief outline of what to expect if you’ve not done this survey before is also included. We guarantee you’ll have a really good time if you choose to become a volunteer.
Also, if you want to contact Courtney directly about the training or have questions,

First Session / Sat., Feb. 1 / 9:00 a.m. to Noon / Ranger Visitor Center Auditorium
Second Session / Sun., Feb. 9 / 9:00 a.m. to Noon / Ranger Visitor Center Auditorium

But first, little background about the study area from Cooper Ecological Monitoring.

Griffith Park, including the Los Angeles River channel, is home to about 150 regularly-occurring bird species. Intensive fieldwork following the May 2007 wildfire documented nearly 100 species in the park (exclusive of the L.A. River). Raptors are of particular interest since many tend to use the same nests or nesting sites year after year, and are of high interest to both the public and to conservationists. Because they vary in disturbance tolerance, raptors are good indicators of ecosystem health.

During each of the past 3 seasons (spring/summer), volunteers have documented 50-60 active each year within c. 10 km of Griffith Park. The Red-tailed hawk remains our most numerous species (more than half the detected nests each year), with Cooper’s Hawk, Red-shouldered Hawk and Great Horned Owl less common but still widespread. Unfortunately nests of American Kestrel remain elusive, although a probable territory has been noted in the Elysian Valley near the former Taylor Yards railway yard. In addition, Cooper Ecological received regular reports of likely nesting by Western Screech-owl and Barn Owl, but have yet to fully document these species within the study area.

Monitoring Schedule
Late Jan./Feb.: Volunteer training, led by Dan Cooper and Courtney McCammon; nest-searching, including re-visiting known nest sites.
March: Volunteers deployed to monitor nests as they are confirmed/discovered; new nests continue to be located, and basic data taken on substrate/tree species, topography, etc.
April-June: Volunteers continue to monitor nesting activity, as the first fledglings emerge and leave the nest by the end of June.
July: Volunteer party; report-writing.
