You feed small songbirds and put up nest boxes to attract them. Why not do the same for owls?<\/b><\/p>\n

Your yard probably already has the worms, frogs, mice, rats, gophers, and rabbits that owls eat.<\/p>\n

Owls eat a lot of rodents! Cute and beneficial–who could ask for more!<\/p>\n

If you install an owl nesting box you can likely attract owls to your backyard. <\/p>\n

The easiest owl in the U.S. to attract to your yard with a nest box is the Screech Owl. <\/b><\/p>\n

In recent years scientists discovered that there are actually 2 species of owls in North America formerly considered one. We now have Eastern Screech-Owls<\/b> (Megascops asio)<\/i> and Western Screech-Owls<\/b> (Megascops kennicottii)<\/i>. These go along with another screech owl in the United States, the Whiskered Screech-Owl<\/b> (Megascops trichopsis)<\/i> found mostly in Mexico, but barely reaches into SE Arizona and SW New Mexico.<\/p>\n

Nearly wherever you live in the United States, then, (except for parts of central Wyoming, northern Michigan, northern Minnesota, northern Wisconsin, Maine, New Hampshire, Vermont) you can attract Screech Owls to your backyard.<\/p>\n\n\n\n\n

<\/span>What makes your yard attractive to owls?<\/span><\/h2>\n

Owls need food, water, shelter, and a place to nest.<\/p>\n

Your yard provides the food. It doesn’t take much “wild” space to attract owls. They can find food in the leaf litter under larger trees, or in the trees themselves. They can find food in taller grass in a vacant lot or field next door. There are almost always mice and rats in our yards that we never know about.<\/p>\n

Put your outdoor lights on timers<\/b> to turn off late at night. Owls like it darker.<\/p>\n

You can provide a bird bath for owls<\/b>. You’ll probably never know, though, that they’ve been there for a dip in the night.<\/p>\n

Dense trees and gnarled larger trees<\/b> make the best spots for owls to roost and sleep during the day.
\nTrees with cavities in them provide a nesting place. But you can provide an owl box for nesting, too.<\/p>\n\n\n\n\n

<\/span>Screech Owl nests in nature<\/span><\/h2>\n

Screech Owls nest in cavities.<\/p>\n

Frequently, cavities excavated by woodpeckers<\/b> serve as nests for Screech Owls. <\/p>\n

Larger woodpeckers that provide nest holes for Screech Owls include Acorn Woodpeckers, Red-headed Woodpeckers, Red-bellied Woodpeckers but, especially, Northern Flickers<\/b>. Do you have any of these woodpeckers in your neighborhood? Then you may already have Screech Owls visiting your yard!<\/p>\n

Natural cavities can form in trees due to rot or broken off branches. Oak trees, maple trees, cottonwoods, and old orchard fruit trees tend to form such suitable hollow limbs or trunks.<\/p>\n

Rarely, Screech Owls nest in cut banks or cliffs.<\/p>\n

The male Screech Owl scouts out and finds possible nest sites. He will lead his mate there. Often he provides her food to show he is a good provider. Finally, the female selects the best nest site. They may return for several years to the same nest site. They may roost in the nest throughout the year.<\/b><\/p>\n

The owls don’t add any material to the cavity for the nest.<\/b> <\/p>\n

On average, good nesting cavities are about 1 to 1.5 feet deep. The entrance hole is usually just large enough to get in. If it is too much larger other predators (raccoons, larger owls) can get in.<\/p>\n

Screech Owls begin courtship as early as January in southern areas with nesting and eggs as early as February<\/b>. <\/p>\n

In more northerly areas birds sitting on eggs can be as late as July<\/b>.<\/p>\n

Screech Owls lay 2-8 (usually 4-5) eggs. Incubation lasts about 26-34 days until the eggs hatch. <\/p>\n

Juveniles usually first fledge and leave the nest about 28 days after hatching.<\/p>\n

Parents will feed the young outside the nest for 8 to 10 weeks. The young may return to the nest cavity to roost at night during this time.<\/p>\n

<\/span>The Screech Owl nest box<\/span><\/h2>\n

Screech Owls will readily use artificial owl birdhouses. You can build your own as a DIY project. If you purchase or make a box, make sure it is close to the following dimensions.<\/p>\n

The box should be made from untreated and unpainted wood. Pine or cedar makes a good choice. A thickness of 3\/4 inches provides durability and insulation.<\/p>\n

Screech Owl nest box dimensions<\/h3>\n

The box dimensions are as follows. The floor should be about 10×12 inches. The height of the box should be 14 inches. The entrance hole should be 3 inches in diameter, centered 9 inches from the floor.<\/p>\n

The roof should overhang slightly and slope down in front so rain water doesn’t drip into the nest. Recessing the floor up inside a bit should keep water from seeping in. Be sure their are drain holes at the corners of the floor.<\/p>\n

Do not add a perch<\/b>, as perches make it easier for predators to reach the eggs or young. Instead, make the entrance hole with double-thick wood<\/b> to keep potential predators from being able to reach inside.<\/p>\n

One side of the nest box should be hinged for cleaning after the nesting season is over<\/b>. The boxes should last 2-3 seasons before they need replaced.<\/p>\n

Cut grooves or attach small strips of wood inside the box<\/b> below the entrance hole. This allows the owls to get out of the owl box more easily.<\/p>\n

Whether you make your own owl nest box or purchase one, look for these dimensions.<\/p>\n

Screech Owl nest box dimension overview<\/b><\/p>\n

    \n
  • Floor 10×12 inches<\/b><\/li>\n
  • Height 14 inches<\/b><\/li>\n
  • Entrance 3 inches in diameter, 9 inches up from floor<\/b><\/li>\n
  • Box height 10-30 feet above ground<\/b><\/li>\n<\/ul>\n

    Add 2 to 3 inches of wood shavings in the bottom of the box. After each nesting season replace the wood shavings putting in the box 2-3 inches of fresh shavings.<\/p>\n

    Here is one that has the correct dimensions and good reviews (includes hinged sides and wood shavings). (You will still need to figure out for yourself how to mount it.)<\/p>\n

    Screech Owl nest box placement<\/h3>\n

    Nest boxes for Screech Owls should be placed 10 to 30 feet above the ground<\/b>. Do not place multiple Screech Owl boxes closer than 100 to 1000 feet apart (I have seen both distances referenced). <\/p>\n

    Screech Owls are territorial. They will chase away other owls in this 1000 foot radius. On the other hand, having an alternative nest box for the pair allows the owls to choose their preferred nest site. It also give them a second place to nest if the first attempt fails. Or it gives a place for other birds to nest.<\/p>\n

    Ideally, the entrance hole should face southeast<\/b>. Face the front of the owl box in a direction ranging from east to south. Screech Owls love to sit in the entrance hole and warm by the rising sun. Avoid placing the nest entrance facing between north and west.<\/p>\n

    Owls are rather messy around their nest site.<\/b> So choose a location where white wash (owl poo) will not be a problem. You may also observe owl pellets (regurgitated bones and hair) under favorite perches.<\/p>\n

    When should you put up an owl box? Owls may roost in the box any time of year.<\/b> But for nesting in the next season put up the box in the fall<\/b> before the male owl begins scouting for possible nest sites in winter.<\/p>\n

    If you place the nest box in a tree<\/b>, consider placing the box under a branch. Young owls climb out of the nest box onto the top of the box and flap-hop out on nearby branches. The owls don’t like any branches blocking the entrance hole, though.<\/p>\n

    You may place a nest box on the east or south side of a barn<\/b> or other tall out building. Hang the box under the eaves to protect from rain, but also so that predators can’t jump down from the roof.<\/p>\n

    Using a pole mounted nest box<\/b> will work too. A pole may be best to keep out squirrels which may climb trees to take over the owl box. Use a baffle on the pole to keep squirrels from climbing up. Place the pole 10 feet from a tree or structure where the squirrel could jump across to the box.<\/p>\n

    Owls do like a staging perch placed about 12 feet from the nest entrance<\/b> and about 6 feet off the ground. A shepherd’s hook works well for this. So will a wooden raptor perch on a pole. The owls will land here first before flying into the nest box. The male will perch here and guard the nest while the female is inside incubating.<\/p>\n

    Nest box competitors and maintenance<\/h3>\n

    The Screech Owl nest box dimensions are also suitable for other birds and animals who may try to take over the box for roosting or nesting.<\/p>\n

    European Starlings<\/b> and various tree squirrels<\/b> may try to take over the box. They will fill the box with straw (starlings) or leaves (squirrels). Remember that the owls don’t add any material to nests. Starlings may take several days to a week to build their nest. So try to remove the invading nesting material before the starlings lay eggs. If you see starlings or squirrels inspecting your box you need to do so, too. Remove any foreign material they may have added.<\/p>\n

    These nest boxes are also perfect for American Kestrels<\/b> and Northern Flickers<\/b>, too. These are desirable birds, so I wouldn’t be too upset if they nested instead of the owls. Remember, owls generally nest earlier in the spring than other birds. So if the kestrels or flickers begin nesting in the boxes in May or June, the owls likely aren’t going to nest this late in the year anyway.<\/p>\n

    Put up nest boxes in the fall<\/b> or early winter so owls find them when they start scouting for nest sites in January. Raising young in a nest is messy. The nest box may become infested with various insects. Clean out the nest box in fall. Put in 2-3 inches of new wood shavings.<\/p>\n

    <\/span>Wrapping Up<\/span><\/h2>\n

    Before putting up an owl nesting box in your garden, there are several important things to consider to ensure its success and the well-being of the owls:<\/p>\n

    Habitat suitability:<\/strong><\/p>\n

      \n
    • Owl species:<\/strong> Identify the owl species you want to attract and research their specific habitat requirements. Different owls prefer different box sizes, locations, and surrounding landscapes.<\/li>\n
    • Food availability:<\/strong> Ensure your garden and surrounding area offer a plentiful food source for the owls. This could include small rodents, insects, and other prey.<\/li>\n
    • Quiet and disturbance:<\/strong> Owls prefer quiet, undisturbed areas. Choose a location away from busy roads, loud noises, and frequent human activity.<\/li>\n
    • Competition:<\/strong> Check for potential competition from other nesting birds or existing owl territories in your area.<\/li>\n<\/ul>\n

      Box placement:<\/strong><\/p>\n

        \n
      • Location:<\/strong> Mount the box on a sturdy tree trunk, building, or pole at least 10-15 feet high. Choose a location protected from strong winds and direct sunlight.<\/li>\n
      • Orientation:<\/strong> Face the box entrance north or northeast for protection from prevailing winds and hot summer sun.<\/li>\n
      • Clearance:<\/strong> Ensure the entrance hole is clear of branches and other obstructions.<\/li>\n
      • Safety:<\/strong> Avoid placing the box near windows, doors, or other areas where humans or pets could disturb the owls.<\/li>\n<\/ul>\n

        Box design:<\/strong><\/p>\n

          \n
        • Material:<\/strong> Choose a weather-resistant material like untreated wood or cedar to avoid overheating and toxic chemicals.<\/li>\n
        • Dimensions:<\/strong> Select the right size box for the specific owl species you want to attract. Consult owl conservation websites for recommended dimensions.<\/li>\n
        • Drainage:<\/strong> Drill drainage holes in the bottom of the box to prevent water accumulation.<\/li>\n
        • Cleaning and predator control:<\/strong> Make the box easy to open for cleaning and potential predator removal. Consider installing a predator guard below the entrance hole.<\/li>\n<\/ul>\n

          Additional considerations:<\/strong><\/p>\n

            \n
          • Legality:<\/strong> Check for any local regulations or permits required for installing owl nesting boxes.<\/li>\n
          • Monitoring:<\/strong> Observe the box discreetly to see if it’s being used. Avoid disturbing the owls during nesting and raising their young.<\/li>\n
          • Patience:<\/strong> It may take time for owls to discover and use your nesting box. Don’t get discouraged if they don’t come immediately.<\/li>\n<\/ul>\n

            <\/span>Frequently Asked Questions<\/span><\/h2>\n

            Do owl nesting boxes work?<\/strong><\/p>\n

            The surrounding habitat has a major impact on whether an owl will take up your nesting box. If your garden offers an abundant food source, minimal disturbance, and suitable landscape features for a specific owl species, the box is more likely to be used. <\/p>\n

            Choosing the right size box, constructing it from appropriate materials, and mounting it in a safe and secluded location all contribute to its appeal for owls.<\/p>\n

            Minimizing competition from other birds and taking measures to deter predators like raccoons further improve the box’s attractiveness and the owls’ success.<\/p>\n

            It may take time for owls to discover and utilize the box. Patience and discreet monitoring help ensure you don’t inadvertently deter them during the crucial nesting and chick-rearing period.<\/p>\n

            What time of year do you put up an owl box?<\/strong><\/p>\n

            The best time to put up an owl box depends on a few factors, specifically:<\/p>\n

            1. Owl species you want to attract:<\/strong> Different species have different breeding seasons and may be more receptive to a new box at different times. Here’s a general guide:<\/p>\n

              \n
            • Screech Owls:<\/strong> Mid-March to July<\/li>\n
            • Barn Owls:<\/strong> December to early March<\/li>\n
            • Great Horned Owls:<\/strong> January to April<\/li>\n<\/ul>\n

              2. Local climate:<\/strong> In warmer climates, you can install a box earlier, even as early as October or November, giving owls more time to become familiar with it before breeding season. In colder climates, wait until closer to the breeding season to avoid exposing the box to harsh winter conditions.<\/p>\n

              3. Existing owl activity:<\/strong> If you already see owls in your area during their breeding season, you can put up the box a couple of months before they typically nest. This gives them time to discover and assess the potential nesting site.<\/p>\n

              How close to a house can you put an owl box?<\/strong><\/p>\n

              The acceptable distance for an owl box from your house depends on several factors, including the specific owl species you’re hoping to attract, their tolerance for human activity, and your personal preferences. Here’s a breakdown:<\/p>\n

              Owl Species Tolerance:<\/strong><\/p>\n

                \n
              • Highly tolerant:<\/strong> Barn Owls can often nest successfully in boxes attached to buildings or even inside barns or garages. Minimum distance of 30 feet is recommended, but they’ve been known to nest much closer with minimal disturbance.<\/li>\n
              • Moderately tolerant:<\/strong> Eastern Screech Owls might tolerate boxes around 50-75 feet away from houses, especially if there’s intervening vegetation or structures.<\/li>\n
              • Less tolerant:<\/strong> Great Horned Owls generally prefer more secluded areas and might avoid nesting within 100-150 feet of human activity.<\/li>\n<\/ul>\n

                Considerations:<\/strong><\/p>\n

                  \n
                • Noise and light:<\/strong> Minimizing noise and light disturbances near the box is crucial for any owl species. Consider additional barriers like shrubs or fencing if the house is closer than the ideal distance.<\/li>\n
                • Human activity:<\/strong> Avoid placing the box in areas with frequent foot traffic or close to windows and doors where owls might feel observed.<\/li>\n
                • Chick-rearing period:<\/strong> During chick-rearing, owls can be more vocal and potentially disruptive. Consider the potential noise impact when choosing a location.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"You feed small songbirds and put up nest boxes to attract them.
