I do the exact opposite. I kill big mature trees so hawks and owls have places to sit and hunt. I don't want birds or rodents in my orchard at all. I also fell old beech trees near my fruit trees to make the cavities unattractive to raccoons and cavity nesters.
Lots of birds eat insects, many of which are beneficial to fruit trees. Rodents like voles and mice like to burrow under mulch and snow and eat the bark off apple trees. Rabbits are very efficient tree killers too.
Woodpeckers will strip a cherry tree of fruit in a day. Thrushes and magpies eat my cherries and peck holes in my apples and knock them off the trees. They also eat my gooseberries and currants. And they love to do all this right before the fruit is ripe.
And don't forget the arch nemesis of fruit trees, the yellow-bellied sapsucker, is a cavity nester, so any birdhouse in an orchard would be a dream come true.
I did, however, build a few dozen birdhouses through the years and put them in the forests and grasslands to encourage more birds to live near the places I used to frequent. I might some day put up a few more bluebird houses with tar-treated roof boards to see if that might help me see more of them. The last few "birdhouses" I built were actually mallard tubes for the neighborhood and the local Hunting Association's terrain.
My indoor free time in winter is generally spent reading about hunting, habitat work, and guns and trying too find bargains online. Otherwise I'm in the garage cutting up pallets, cleaning up, and practicing welding.
