Best Screech Owl Boxes 2026: Cedar & Pine Nest Boxes Ranked

Quick Answer: The best screech owl box in 2026 is the Coveside Saw-Whet and Screech Owl House — solid eastern white pine built to the 8”x8” floor and 3” round entrance-hole specifications wildlife agencies recommend, at $84.99. If you want one box that also works for American Kestrels, the Coveside Kestrel & Screech House is sized for both. Whichever you buy, mount it at least 10 feet up with a predator baffle below it, add a couple of inches of wood shavings, and leave it up year-round — screech owls use nest boxes for winter roosting as well as spring nesting.

Eastern Screech Owls are one of the few owl species that will reliably move into a human-made nest box, and unlike songbirds they don’t add any nesting material of their own — they just need a cavity sized correctly and mounted high enough to feel safe. Cornell Lab of Ornithology’s All About Birds estimates a global breeding population of roughly 560,000, rated low conservation concern, but the species still depends heavily on dead-tree cavities that get removed from managed yards and woodlots long before natural replacements form. A properly sized box fills that gap, and because screech owls roost in cavities year-round, a box that never lands a spring nesting pair can still earn its keep as a winter shelter. Here are the boxes that get the dimensions right.

Screech owl boxes by the numbers

• A 3-inch entrance, 12 inches up. The standard screech owl box specification calls for a 3-inch round entrance hole positioned about 12 inches above the floor — larger than a bluebird’s 1.5-inch hole, smaller than a wood duck’s 4x3-inch oval, and sized to admit an owl or kestrel while keeping most competitors out.
• An 8x8-inch floor, 15 inches deep. Wildlife-agency plans (Tennessee Wildlife Resources Agency, Audubon) specify an 8-inch by 8-inch floor with roughly 15 inches of floor-to-ceiling depth — enough room for a hen and her clutch without the box feeling like an open platform.
• 10 feet minimum mounting height. Wildlife guidance places the box at least 10 feet up a tree or pole at the edge of woods, a field, or near wetlands — high enough to discourage ground predators from an easy reach.
• ~560,000 breeding birds. Partners in Flight’s estimate, cited by Cornell’s All About Birds, puts the global Eastern Screech Owl breeding population at roughly 560,000 — a species of low conservation concern, but one that still leans on cavities we increasingly remove from managed landscapes.

Our top picks at a glance

1. Coveside Saw-Whet and Screech Owl House — Best Overall

Putting this up before owls start scouting cavities in late winter? Try Kindle Unlimited free for owl field guides and nest-box monitoring how-tos while you wait to see who moves in — useful reading if this is your first cavity-nesting species beyond songbirds and feeders.

Coveside has built wildlife housing for decades, and this is the box most retailers point to first because it simply matches the dimensions agencies actually recommend: a 3-inch round hole, adequate floor space, and solid wood that weathers for years without rotting. It shares a design with Coveside’s saw-whet owl housing since the two species have nearly identical cavity needs, so the same box works for either.

The rougher-head exterior finish isn’t cosmetic — it gives an owl’s talons something to grip on the way in and out, the same reasoning behind the unfinished-wood recommendation on most wildlife-agency plans. Mount it at least 10 feet up with a predator baffle on the pole, add a couple of inches of wood shavings, and leave it up through winter as well as spring.

2. Coveside Kestrel & Screech House — Best Dual-Purpose

American Kestrels and Eastern Screech Owls have nearly identical cavity requirements — same hole size, similar floor footprint — which is why most manufacturers sell a single “owl/kestrel” box rather than two separate products. If you’re mounting near open farmland where kestrels hunt as well as wooded edges where screech owls roost, this is the box that keeps both options open instead of committing to one species.

Whichever tenant moves in first tends to keep returning in following years, since both species show strong site fidelity to a cavity that already worked once. Check it in late winter regardless of what used it last season — a starling claim can shut out either species just as easily.

3. Woodlink Screech Owl & Kestrel House — Best Value

Cedar’s natural rot-resistance means Woodlink can skip some of the finishing steps a pine box needs and still hold up outdoors for years, which is part of why this one typically undercuts the Coveside pine boxes at most retailers. The dimensions match the same 3-inch-hole, 8x8-inch-floor specification, so you’re not trading away function for the lower price — just paying for a different wood species.

It’s a reasonable first box if you’re not certain screech owls are active near your property yet and don’t want to commit to a premium pine box before finding out. If it fills, upgrading a second location to a Coveside box later is an easy call.

4. JCS Wildlife Screech Owl / Saw-Whet House — Best Weather-Durable Roof

The poly-lumber roof is the differentiator here — every other box on this list uses a wood roof that eventually needs resealing or replacing, while JCS Wildlife’s recycled-plastic panel shrugs off UV and moisture indefinitely. If you’re mounting in a spot you won’t check often, that’s one less maintenance task to remember.

Everything else matches the field: cedar body, 3-inch hole, and the same rough dimensions wildlife agencies recommend. It’s a reasonable pick if long-term low-maintenance matters more to you than matching the exact material Coveside or Woodlink use.

How to choose a screech owl box

• Match the standard dimensions. An 8”x8” floor, roughly 15 inches deep, with a 3-inch round entrance hole about 12 inches above the floor — a box built to spec is what actually gets used.
• Mount at least 10 feet up. On a tree or pole at the edge of woods, a field, or near wetlands, facing away from prevailing wind and harsh afternoon sun.
• Add a predator baffle. The same cone or stovepipe baffle you’d use on a bluebird or purple martin pole keeps climbing predators away from eggs and roosting owls alike.
• Use uncoated wood. Cedar, redwood, or white pine at least 3/4 inch thick — no paint or sealant on the interior, which can trap moisture or leave residue an owl doesn’t need.
• Add shavings, not nesting material. A couple of inches of wood shavings or sawdust cushions the eggs; screech owls don’t build or arrange a nest the way songbirds do.
• Check for starlings in late winter. Before screech owls start scouting cavities, clear out any loose nesting material a starling has already claimed the box with.
• Leave it up year-round. Screech owls use boxes for winter roosting as well as spring nesting, so a box that never fills with eggs in April may still be earning its keep in January.

Screech owls are one of several cavity-nesters worth housing beyond a standard seed feeder: our best wood duck box guide covers a much larger cavity nester with its own oval-entrance and predator-guard rules, our best purple martin house roundup covers the PMCA’s rules for a colonial cavity nester, and our best bird house guide has the smaller bluebird, wren, and chickadee boxes that share the same uncoated-wood and predator-guard principles at a smaller scale.

The bottom line

The Coveside Saw-Whet and Screech Owl House is the best screech owl box for most people — solid pine built to the standard 3-inch-hole, 8x8-inch-floor specification, at a price that doesn’t cut corners on material. If you want one box that also hosts American Kestrels, the Coveside Kestrel & Screech House covers both. On a budget, the Woodlink cedar box matches the same dimensions for less, and if low-maintenance matters most, the JCS Wildlife poly-lumber roof skips the eventual roof replacement the others will need. Whichever you choose, remember what actually decides success: the 3-inch entrance hole, a mounting height of at least 10 feet, a predator baffle, and a box left up year-round instead of just for spring.
