观察细节
Heard familiar calling sound from hidden near top of trees at 37.72608114842144, -122.11558264884796. Merlin App appeared to confirm identification as PF. I have heard this sound at Pine Canyon Nesting site (Castlerock) when the Falcons call to each other. Ravens and Scrub Jay in area were agitated. However, when I returned back to area to confirm I saw two Steller's Jays in the area so more likely this was mimicking. These Jays do a good imitation of a Red Shouldered Hawk too.
