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.

Sadly I cannot see the pics. But having known an American Kestrel up close and personal, I know they are incredibly beautiful and colorful falcons. They will sometimes take small birds, but definately not their primary diet. They will nest in appropriate nestboxes in the right habitat, but they also have to compete with the invasive European Starling. When we lived on a farm, we had kestrels nest in a box mounted right outside our window, so we could watch them bring food to their young, and perch nearby to hunt. What a wonderful memory. Here is a link that might be useful: http://www.mn.nrcs.usda.gov/technical/ecs/wild/kestrel.pdf

The bird is not chubby. It's merely fluffing its feathers in cold weather. This is a very characteristic posture in winter. In an instant it can compress its feathers against the body and take on a sleek, aerodynamic form. We, too, are seeing a decline in kestrels in Ohio, totally from a lack of nest sites. Old rural buildings are being lost, and there are no large cavities in trees. The bird is ever more dependent on provided nest boxes. But one up (properly), and kestrels will come.

Oooooh. Darling little precious hijackers. Please don't call in the heavy artillery. No need to alert homeland security either. : )
