In case anyone asks, those artificial raptor perches we (the county) put up in the open space areas on Mount Diablo DO work.
I got up to North Lime Ridge early for a work party so I could look around and saw a red-tailed hawk on one of the perches. I stopped and watched.
It dropped off the perch and grabbed a ground squirrel, then flew back up to the perch and removed what it didn’t want to eat, and left those parts on the perch and flew off to a less open area to enjoy the ground squirrel in peace.
The County Ag. Dep. lady who works on that found Jerusalem cricket parts in a nice pile next to where the cricket had been eaten by a pallid bat as apparently the bat caught the cricket and then hung from the raptor perch to enjoy its meal. Nice to know at night we have those around here.

It’s really great to know that those artificial raptor perches are working as planned. And being used by bats, too, eh? I’ve also seen songbirds using them. Those perches are a super idea. Something simple and easy to install with wide-ranging positive benefits. Good show! /Gary
