Saw whet owl leaving eaten mice in my driveway - wouldn't mind the free pest control but my young kids play in the driveway

I don't know a lots about owls. I do know that I find it strange when I start to find chewed up mice and mice skeletons in my driveway in or about the same place every day. I have a row of about 6 arborvitae trees that are probably about 20 feet tall where he took up residence. That makes the trees hard to trim at higher levels, so there is an overhang on to my driveway of branches. This baby owl decided to make a nest here, and regurgitate mice onto my driveway, where my kids play and bounce balls.

I didn't want to hurt the owl and I know they are nocturnal; so they'd vulnerable in the day if I could get up high enough on a 10 foot step ladder to take a picture. I eventually did. I didn't touch him or hurt him in any way. I needed to get rid of him because I can't have dead rodents where little kids are playing.

I ended up leaving a spot light plugged in for a few nights pointed at the trees and he went away and found a new home. He could've moved further into the same trees, where the rodent bodies would've fallen into grass and thick brush for all I I know. I just needed to get him to stop dropping his prey on my driveway.

Here is my best picture.

Here are my other two that aren't as good.

Here is a picture I found on the internet, so you can see one better for reference.

I am fairly sure I identified the owl properly. Do you bird experts agree? I think this is the same type of owl. I live in the Philadelphia, PA area. They say in some articles I read, that these birds do live in the Northeast US. Feel free to correct me if I'm wrong.
