Pinnacles Raptor Monitoring Update for March 2023

Hi Everyone,

The following update details the status of breeding raptor activity at the park so far this season.

Prairie falcons (PRFA) and peregrine falcons (PEFA) have returned to nesting territories and are actively inspecting and preparing cliff cavity nest sites. Raptor advisories are in effect to help protect these magnificent raptors from disturbance, and advisory signs are posted at Balconies, Hawkins Peak, and near Little Pinnacles / Yaks Wall. For current advisories in effect, refer to the PINN raptor advisories page - and feel free to ask me for further clarifications.

For the 2023 season, PRFA and PEFA have been confirmed occupying nine and four territories respectively. The falcons are not yet nesting but should be selecting nest sites for egg incubation within the next few weeks. For information on territory locations and rock formations, refer to Brad Young's climber's guidebook to Pinnacles.

PRFA and PEFA breeding efforts for 2023 are listed below:

  • Resurrection Wall: PRFA pair
  • Egg / Teapot Dome: PRFA pair
  • South Balconies: PRFA pair
  • Crowley Towers: PRFA pair
  • Willow Spring Slide: PRFA pair
  • South Chalone Peak: PRFA pair
  • North Chalone Peak: PRFA pair
  • Drywall Slide: PRFA pair
  • Gargoyle / Piedras Bonitas Cliffs: PRFA pair
  • Little Pinnacles / Yaks Wall / The Hand: PEFA pair
  • Hawkins Peak: PEFA pair
  • General / North Balconies: PEFA pair
  • South Chalone Peak: PEFA pair

As noted above, climbing and hiking advisories are in effect for the 2022 season. The official park website reflects current advisories in effect, as do the Friends of Pinnacles and Mud 'n Crud websites (linked to on the Pinnacles website). Let me know if you have further questions.

PRFA and PEFA are actively defending territories and will alarm call or dive at intruders (including people!) that get too close to their intended nest sites.

In addition to PRFA and PEFA, other raptor species active in the park this year include American kestrels, red-tailed and red-shouldered hawks, great horned, western screech, and barn owls, and Cooper's and sharp-shinned hawks.

Two golden eagle pairs have also been confirmed occupying historic territories, in the park and just outside of the west side entrance. Like cliff-cavity nesting falcons, golden eagles are quite sensitive to human disturbance, so it is exciting to see golden eagle pairs in the area - they should begin nesting efforts soon!

This year several people are assisting with raptor monitoring at Pinnacles - Mike Baird, Joseph Belli, Kaitlin Lopez, and Megan Gnekow. All of them have been working with the condor and / or raptor monitoring programs for years, and their assistance in confirming raptor status at the park is greatly appreciated!

Thank you to all the staff who have continued to provide me with raptor observations; every detail on raptor behavior helps to provide a more complete picture of raptor breeding at the park. If anyone on staff wishes to report raptor or other observations, I would greatly appreciate it if you please email details of observations including species, date, location, and times. Your reports help us comprehensively track raptor activity at the park over the years.

If you have any observations within the park to report, or any raptor-related questions, please contact me via email or extension 4279. Thanks!
