We live near a lagoon with a lot of birds, many migrating, also see hawks - think it's red shoulder, that sometimes land on telephone poles, but have never seen any owls. We live near the beach. A few years ago, I worked at an in-land hospital on the 3rd floor. It had recessed windows on the upper floors. A pair of barn owls raised 2 fledglings on the window sill. It was amazing that the little tykes didn't fall off the ledge, especially since the parents were gone frequently hunting for food. I was surprised to see them in such an environment - in the middle of a bustling city - and especially the place they chose to lay their clutch. Still trying to decide the best approach to keeping the damage down from the mole/vole diggers. I want to create a water-conserving front yard anyway, so the lawn isn't being watered - so perhaps that in itself may be a deterrant, however, in the back yard, my main concern is for my newly planted dwarf apple trees - they are doing so great, would hate to lose them now. Thanks for your thoughts. Bejay

Thanks joepyeweed! As far as the entrance hole being enlarged, I think that's a problem in terms of predators entering the box. I'm not certain, but it's my guess based on the premise there's a recommended entrance hole size to being with. I didn't do anything to keep squirrels out. Both squirrels and birds had put quite a bit of nesting material in the box, which we cleaned out after the owl exited one night. Besides Chris' Eastern Screech owl web site, the best info. I've gotten on E S owls has been from Frederick R. Gelbach's book, The Eastern Screech Owl. Here is a link that might be useful: owl box info.

Vonyon, I listened to the recordings of the barn owl and then the screech owl. I'm certain it was not the barn owl. The first time I heard the sound (which was the summer before last) it sounded like the "a" call. I went in immediately and listened to various owl calls to decide if it was an owl and which one. Then, on Halloween (last year), I was outside and I heard sound "B". Around the same time I heard some voices of kids on another street, so I thought it was some kind of recording that they had; however, I heard it again sometime after that and checked out the owl calls again and determined it was the screech owl.

Animals can be so strange....you may put all your time and effort into building just the right box, selecting a 'perfect' site, and then....nothing. Or the opposite may happen, and it will seem as if they were sitting around WAITING for you to get their new home up and going for them. I think it's different for everybody, but you will have to be PATIENT. Years ago we got a booklet from the DNR that had blueprints and general info for houses that were specific for each species. We looked it over and chose to make wood duck boxes, thinking they would have a place to nest by our pond. What we learned, in fact, was that many species simply don't care if a box is not "designed" for them...if they can get their bodies through the hole, there's nobody already at home (depending on the animal this may not matter either) and the place seems safe enough, it's a done deal. Not only will screech owls use a duck box as a day haven, they will indeed nest and rear young in them. There is a slough I frequent that has three duck boxes on it, and during one spring I discovered one particular box was home to a nest of screechies. I think the slough was dry that year, but usually this box is surrounded by about 2 1/2 feet of water...a rough first flight for any chick. I can't recall how many chicks were in that nest...I will have to try to dig out the animal album and find the photos. But they will use a duck box. When we first hung out duck boxes here at our place, I was getting frustrated waiting. It was something like three years before we finally found a nest, and then all three boxes had action!! It's worth the wait, so hang in there. But I'm still waiting for bats to use their house....I don't think they need any extra places with all the shagbark hickories. But the winner in my Crazy Nester category goes to the bluebirds at my dad's place. For the past three years, there has been a pair of bluebirds nesting in his martin house. Not a thing to be seen of any martins, but these blues are shoulder to shoulder with house sparrows and to this day I don't yet understand how they are pulling this off.
