We have a great horned owl who lands on our raptor perch just about every morning and every night. The great horned owl is doing its job in helping us with rodent control. It is important to use alternatives to rodent poisons and let our raptors help us!
I include a link to the Raptor Pilot Study for Levee Protection. The Ventura County Watershed Protection District (WPD) completed the study to see if raptors such as hawks and owls can reduce ground squirrels around dams and levees. You can read about the success of the findings below.
We built two perches and put them up on 3/8/2020. We are delighted to see hawks and owls enjoying the perches. I would recommend putting cameras up underneath the poles so you can see what birds are using the perches.
We are also moving forward with a project in Old Agoura! Four residents will have owl boxes mounted on poles. We'll keep you posted on the progress!
LESSON LEARNED: Before you purchase a box, ask a lot of questions. Find out if you need to make modifications to the box so it will fit on a pole. As for raptor perches? I LOVE THEM! I wasn't sure if any raptors were landing on them. I see there is a lot of action at night. Our great horned owl is out just about every night and uses our perch a lot. I notice other birds enjoy using the perches! I am a big fan of perches.

If you want to put up an owl box, it is important to notify your neighbors. If your neighbors are using poisons, one poisoned rat could kill the owl family.
