Best bluebird houses

Bluebird houses are the most-searched nest box in North America and the most often bought wrong, because the thing that decides whether a bluebird uses one — the entrance hole diameter — is exactly the figure a decorative box does not state. This page is the general nest box roundup narrowed to one species, with the NestWatch figures as the yardstick. We have not handled these boxes; every dimension is the maker's own, read on the date in the sources, and checked against Cornell's.

What we judged on

1. Entrance hole diameter. NestWatch publishes 1.5 in for Eastern Bluebirds and about 1 9/16 in for Mountain and Western Bluebirds. Much over 1 5/8 in admits European Starlings, which will take the box. A box that does not state the hole size cannot be judged at all.
2. Floor and cavity. NestWatch gives a 5.5 by 5.5 in floor and a 9 in interior cavity for Eastern Bluebirds. A box that publishes its floor can be checked; one that publishes only its outside dimensions cannot.
3. A predator guard. An extended entrance — a thick block or tube around the hole — makes it harder for a raccoon or cat to reach in. Cheap boxes omit it.
4. A clean-out door. Bluebirds raise more than one brood a season and the box should be cleared between them. A box that does not open is a one-season box.
5. No perch. A perch below the hole helps predators and house sparrows and does nothing for bluebirds. Its presence is the surest sign of a decorative box.
6. Ventilation and drainage. Vents near the roof and holes in the floor. Bluebird boxes sit in full sun by design, and an unvented one cooks.

Against the NestWatch Eastern Bluebird spec

NestWatch gives a 5.5 x 5.5 in floor and a 1.5 in hole. This box meets the hole and the width, and runs deeper than the published floor at 8 1/8 in.Source: NestWatch (Cornell Lab of Ornithology), Eastern Bluebird nest box specifications, nestwatch.org, read 2026-09-02

What it gets right

• Publishes the floor, the hole and the overall dimensions — most boxes publish none of the three
• 1 1/2 in guard hole is the Eastern Bluebird figure and small enough to keep European Starlings out
• Front clean-out door and an extended predator guard, both of which cheap boxes omit
• Cedar and rust-free hardware, so it can go up unpainted and stay up

What it does not

• Plain to look at, which is the point but is not what a gift buyer always wants
• Floor is deeper than the NestWatch 5.5 x 5.5 in figure; the maker does not say why
• The 1 9/16 in body hole behind the guard means the guard has to stay fitted to hold the 1 1/2 in size
• Nothing about a correctly built box guarantees occupancy in the first season

Who it is for

Anyone who wants a functional bluebird box rather than a decorative one, and would rather check figures than trust a picture. Mount it on a pole with a baffle, 4 to 6 ft up, facing open ground.

Skip this if

The recipient has no open ground. Bluebirds want a box facing open grass with a clear flight path, and a wooded suburban lot with no lawn is the wrong habitat no matter how good the box is.

What it gets right

• Keeps every functional feature of the plain box — guard, clean-out, vents, kerfs — under a roof that reads as a present
• 1 1/2 in guard hole, the correct Eastern Bluebird figure
• Galvanized roof sheds weather better than a cedar one over the long run
• Lighter than the plain box at 2 lb

What it does not

• The maker does not publish the floor dimension for this model, so it cannot be checked against NestWatch the way its sibling can
• A 6 in depth at 6 3/4 in width suggests a smaller cavity than the plain box, though we cannot confirm the interior figure
• A metal roof gets hot in full sun; site it with afternoon shade
• Decorative styling attracts buyers who then mount it too high or on a tree — read the placement notes

Who it is for

The gift buyer who needs the box to look like something when it is unwrapped, and who will pass on the mounting instructions with it. It is the better-looking of two genuinely functional boxes, not a decorative one wearing a hole.

Skip this if

You want the box to be checkable against a published floor size. The plain WWCH3 gives you that figure; this one does not.

Pick 03

Why placement beats hardware

A squirrel can jump a long horizontal distance and drop a long vertical one. A pole set away from fences, trees and roofs, with a baffle below the feeder, defeats them without any moving parts.

Baffle

A dome or cylinder on the pole below the feeder. It is the component that does the work; a pole without one is just a hook.

Placement

Cardinals prefer feeders within about ten feet of shrubs or trees for cover, so a pole needs to be clear of jumping range but not stranded in open lawn

Height, load rating and pole diameter

Not published by the manufacturer in a form we could verify consistently across this class

What it gets right

• Fixes squirrels, ant trails and awkward hanging spots at once
• Lets you hang several feeders in one place, which is how you get more species
• Works with any feeder the recipient already owns

What it does not

• Needs ground you can drive a pole into
• Cheap poles bend under a full feeder and a wind
• Load ratings are rarely published

Who it is for

Someone with a lawn who has hung a feeder off a fence and watched squirrels empty it. This is the actual fix.

Skip this if

The recipient only has a balcony or a paved yard. There is nothing to sink the pole into and it will not stand up.

Pick 04

Small gardens, where a bluebird box will never be used

Entrance hole

About 1 1/4 in for wrens and about 1 1/8 in for chickadees. Both are smaller than the 1.5 in bluebird standard, and the difference decides which bird moves in.

Why this suits a small garden

Bluebirds want open ground and a 4 to 6 foot post. Wrens and chickadees will use a box among shrubs and trees, which is what most gardens have.Source: NestWatch (Cornell Lab of Ornithology), Eastern Bluebird nest box specifications, nestwatch.org, read 2026-09-02

Material

The feature to check

An opening panel for cleaning between seasons

Published interior dimensions

Not published by the manufacturer in a form we could verify on many listings in this class — compare against NestWatch's per-species tables

What it gets right

• Fits the habitat most recipients actually have
• The smaller hole excludes starlings automatically
• Wrens are quick to adopt new boxes, so occupancy is more likely in year one

What it does not

• Will not attract bluebirds, which is what many gift buyers picture
• Interior dimensions are frequently unpublished
• House Wrens are territorial and may reduce activity in other boxes nearby

Who it is for

A suburban garden with shrubs and trees rather than open lawn — which is most of them.

Skip this if

The recipient specifically wants bluebirds and has the open ground for them. Then the hole size is wrong and the gift will not do what they hoped.

The two boxes against the NestWatch figures

Which of the two

The plain WWCH3 if you want the box you can check. It is the only one of the two that publishes a floor dimension, and its 1.5 in guard hole, front clean-out and extended guard tick every NestWatch box. It is also plain to look at, which is the point and is not what every gift buyer wants. The WWGH3-DECO keeps the guard, the clean-out, the vents and the kerfs under a galvanized roof that reads as a present, and gives up the published floor figure to get there. Both are functional boxes; only one is fully checkable.

Nature's Way sells several other bluebird models. We have listed only the two whose product pages showed them in stock on the day we read them — a farmhouse model and a maple model both flipped between in stock and pre-order across the maker's own pages, and a viewing-window model was sold out. If one of those comes back, it is built on the same hole and guard.

Mounting: the part that decides occupancy

A correct box hung wrong stays empty. NestWatch's figures are 4 to 6 ft above the ground on a pole, facing open ground with a clear flight path, away from dense cover where house sparrows and wrens dominate. A pole with a baffle below the box is the setup that keeps raccoons, snakes and cats off the eggs, which is why the same pole system that saves a feeder from squirrels is on this list. Trees are the wrong mount: they give predators a route up and put the box in shade bluebirds do not want.

• Height: 4 to 6 ft. Almost every box is hung too high.
• Facing: open ground, ideally east or away from prevailing weather, with a perch — a fence line or shrub — 25 to 100 ft away for the fledglings' first flight.
• Spacing: bluebirds are territorial. Two boxes 100 yards apart, not two boxes on one pole.
• Timing: up by late winter. Bluebirds prospect early, and a box hung in May has missed most of the season.
• Cleaning: clear the old nest after each brood fledges. This is what the door is for.

The two birds that will try to take it

House sparrows fit through a 1.5 in hole and will kill bluebirds to take a box. They favor boxes near buildings and dense cover, which is the placement argument again: open ground is the defense. European Starlings are excluded by the hole itself, which is why 1.5 in matters and why a box with a 1 5/8 in or larger hole hands itself to them. If chickadees or wrens are what actually nests in the yard, the honest move is a box with a smaller hole — 1 1/8 in for chickadees, about 1 1/4 in for wrens — which is why the wren and chickadee box is on this list as the alternative rather than as a bluebird pick.
