Buying a birdhouse camera takes about five minutes. Getting a bird to move into it? That can take a couple of seasons.
A feeder camera is instant gratification. Hang it, fill it, and the first chickadee usually isn't far behind.
A nest box doesn't work like that. You're offering a house, and birds shop for houses like the pickiest buyers you've ever met. Door too big? Pass. Too low, facing the wrong way, easy for a raccoon to reach into? Pass, pass, pass.
And even when you get every detail right, you might still wait a season or two, which is completely normal (more on that below).
So most of this guide is about the box itself. The cameras get their turn, but the box is what the birds care about.
The Three Birdfy Nest Models
I've got all three of these up in my yard right now, and my yard is about as shady as they come: a stretch of coastal Oregon packed with tall Douglas firs and Pacific wax myrtle, where direct sun is more of a rare treat than a daily thing.
On paper, they stack up like this:
| Nest Duo | Nest | Nest Polygon | |
|---|---|---|---|
| Camera | Dual 1080p, inside and out | Single 1080p, inside | Single 1080p, inside |
| Night vision | Infrared and white light | Infrared and white light | Infrared and white light |
| Battery | 9000mAh | 5200mAh | 5200mAh |
| Solar panel | 5W | 3W | 2W, built in |
| Material | Bamboo | Fir | Bamboo |
| Entrance plates | 4: 1", 1.1", 1.5", 2" | Not listed | 3 (sizes not listed) |
| Price range | $250 to $350 | $100 to $200 | $100 to $200 |
| Price | Check Price | Check Price | Check Price |
Price ranges are a guide only. Use the Amazon links for current pricing.
The Polygon costs a little more than the standard Nest, but its built-in solar panel is smaller: 2W, compared with the Nest's 3W, feeding the same 5200mAh battery. On paper, that means slower charging for more money.
All three have both infrared and white-light night vision. That turns out to matter a lot, and I'll get into why in the night vision section.
Now, the Polygon's looks. Mine is the blue-front one, and that blue was my biggest gripe.
Good news if you feel the same way: it now comes in a natural wood finish.
Birdfy also sells a cheaper Nest that skips the solar panel. I haven't tried that one.
Start With the Entrance Hole
If you only read one part of this guide, read this part.
The size of that front door decides who can move in. Even more important, it decides who can't.
| Species | Entrance hole |
|---|---|
| Black-capped, Carolina, and Chestnut-backed Chickadee | 1⅛" |
| House Wren | 1" |
| Tufted Titmouse | 1¼" |
| White-breasted Nuthatch | 1¼" |
| Eastern and Western Bluebird | 1½" |
| Mountain Bluebird | 1 9/16" |
| Tree and Violet-green Swallow | 1⅜" |
| Northern Flicker | 2½" |
| Eastern Screech-Owl | 3" |
Two numbers are worth memorizing:
- House Sparrows need at least 1¼". A hole of 1⅛" or smaller keeps them out.
- European Starlings can't get through 1½". A hole that size or smaller keeps them out.
Why those two birds? House Sparrows and European Starlings aren't native, and they're brutal about nest boxes. They'll take over a box and kill the birds already raising a family in it.
Keeping them out helps your chickadees and bluebirds more than anything else in this guide.
Now look at the plates that come in the box. The 2" plate in the Duo's set lets both of those troublemakers right in. I'd leave that one in the packaging.
The Duo's 1.1" plate is the one I'm excited about. Chickadees like a hole right around 1⅛" and House Sparrows need at least 1¼", so this little plate slips right into the gap between them, letting the chickadees in while the sparrows stay out.
In my shady yard, where Chestnut-backed Chickadees already visit the feeders, that's the plate I'd start with.
The 1.5" plate is the all-purpose option. Bluebirds, swallows, titmice, and nuthatches can all use it, and starlings can't squeeze through.
House Sparrows can, though. They're a little shorter than bluebirds and about the same weight, so they fit through any hole a bluebird can. No bluebird box is sparrow-proof, which is one big reason people who run bluebird trails check their boxes so often.
Inside size matters too. Nest box guidance lists a floor size for every species, because a roomy enough floor fits a full clutch of eggs and helps the nestlings stay warm.
About That Night Vision
Nest box monitoring guidance is clear on this one. Use infrared. Easy.
Birds can't see or feel infrared light, so it doesn't disturb them. The same guidance also suggests a camera with no visible power light, or one where you can switch that light off.
White light is different. Imagine a lamp switching on inside the box at night, right over a female sitting on her eggs. The guidance doesn't support it, and I'm not a fan either.
Since all three Birdfy models list both infrared and white-light, full-color night vision, this one comes down to a setting in the app.
Find the night vision option and keep it on infrared while birds are nesting. Is the color footage prettier? Sure. Save it for an empty box.
Funny enough, the marketing sells full-color night vision as the fancy upgrade. With a bird inside, infrared is the one you want.
Where to Put It
Height depends on who you're hoping for:
- Chickadees, titmice, and Red-breasted Nuthatches: 5 to 15 ft
- White-breasted Nuthatches: 5 to 20 ft
- Bluebirds: 4 to 6 ft, with the entrance around eye level, which makes monitoring far easier
- Tree Swallows: 5 to 6 ft
- Violet-green Swallows: 9 to 15 ft, with open air in front of the box
- Screech-owls: 10 to 30 ft
Which way it faces matters, too.
Turn the entrance away from your prevailing wind so rain doesn't blow in, and keep it out of the hottest afternoon sun so the box doesn't cook.
Bluebirds seem to like east-facing boxes. Screech-owls are pretty easygoing about direction, but a common tip is east or south and never north, since they like to sit in the doorway and soak up the sun.
If you can, aim the box toward a tree or shrub within about a hundred feet. Fledglings need somewhere to land on that first wobbly flight, and a good target keeps them up off the ground and away from predators.
After the hole, the mount is your biggest decision.
A free-standing metal pole is the best choice. Predators struggle to climb it, and a baffle slips right on.
Trees are a mixed bag. Chickadees and nuthatches do fine on them, but anything that can climb bark can reach the box, so a tree is a riskier spot for bluebirds.
Fence lines and building walls have the same problem for bluebirds, since climbing predators can get to the box. Boxes close to houses also tend to get claimed by House Sparrows.
That box in the photo at the top? It's on a 12-foot post along my deer fence, the one spot in my yard that gets a little out from under the canopy.
The Duo and the Polygon mount to a pole, a wall, or a tree. The Nest hangs from a bracket. If you've got the choice, pick the pole.
When to Put It Up
Earlier than you think. Get the box up by February in the southern US, and by mid-to-late March farther north.
That feels early, but birds don't wait until egg-laying to pick a spot. Some species settle on a territory three to four weeks before the first egg shows up. Put the box up once you notice nesting behavior and they've already chosen somewhere else.
Roughly when nesting season starts in the middle of the country (it runs earlier down south, where bluebirds can get going in late February):
- Bluebirds: March into early April
- Carolina Wren: mid-March into April
- Screech-owl: late March into April, and it uses the box year round
- Chickadees: late April into early May
- House Wren and Tree Swallow: late April into May
Screech-owl boxes are their own thing. Put them up in fall or early winter, and have them in place by January.
Running late? It's not wasted! Bluebirds usually raise two broods (sometimes more where it's warm), so a box that goes up in May can still catch round two. Birds also use boxes as winter roosts, which is a sweet reason to have one up when it's cold.
Early matters even more with a camera box. In one study of Great Tits, researchers put dummy cameras in before breeding season so the birds could get used to them, then swapped in the real cameras once nest building was well advanced.
Their worry was that a shiny, lens-like gadget showing up mid-season could spook a bird that's already brooding. Box up and empty right now? Perfect.
Mine Are Still Empty (and That's Normal)
All three of mine are empty. No nests, no eggs, no footage of anybody moving in.
I'm telling you because the product photos make it look like a family moves in the first week. When that doesn't happen, it's easy to assume you messed something up.
You probably didn't. The big nest box programs all say the same thing: don't get discouraged if a box sits empty at first. If a species isn't already common near you, it can take a few seasons for birds to find a new box.
Maybe a pair moves in your first spring. Or nobody shows up for two whole seasons, and a bird starts roosting in it over the winter before anyone nests there. All of that is normal, and none of it means the box is broken.
What you can control is the setup: the right hole, height, and mount, up before the season, with a predator guard. Get that right and the odds are on your side.
Past that, the birds work on their own schedule. A camera box at this price can sit quiet for a while, so go in expecting to be patient.
Add a Predator Guard
Guards make a real difference. National nest monitoring data show boxes with guards have about 7% higher nest success, and for some species, like Carolina Wren, the boost is closer to 16%. And with a camera inside, a guard is what keeps you from watching something you'll never unsee.
The gold standard is a stovepipe baffle. You want one about 8 inches across and 24 to 36 inches long, mounted so its top sits 3 to 4 inches below the box, with the top of the baffle at least 4 feet off the ground.
That stops snakes, raccoons, opossums, and cats. Skip the skinny 4-inch PVC versions, because snakes may be able to coil right around them.
A cone baffle about 3 feet across works well against most raccoons, cats, and snakes, though a really determined raccoon or a very big snake can sometimes get past one.
A hole guard (a metal plate sized to the entrance) handles a different problem, which is squirrels chewing the hole bigger. Once a hole gets chewed much past 1½", starlings can start squeezing in.
A roof that sticks out about 5 inches past the front helps too, since it makes it harder for raccoons and cats to reach down into the entrance.
None of these are perfect. A decent guard still beats no guard by a mile.
One last thing, and it's a big one: no perches! Cavity nesters grab the edge of the hole and pop straight in. A perch does nothing for them. What it does do is help predators get at the box, and it tends to attract House Sparrows.
When I see a perch on a nest box in product photos, I can tell nobody who actually monitors nest boxes was consulted.
Watch Out for Heat
Nest boxes run hotter than the air around them, sometimes by several degrees.
Past roughly 107°F inside, eggs and nestlings die. Even below that, long hot stretches can dehydrate them and slow their growth. Darker boxes can run noticeably hotter than light ones, too.
Standard specs call for ventilation (two 5/8" holes near the top of each side wall) and drainage (at least four 3/8" to 1/2" holes in the floor). Without those, you've basically built an oven.
Whatever camera box you buy, look for both. Then mount it somewhere out of the hard afternoon sun.
Where a Camera Box Really Shines
The best reason to get a camera box has more to do with the birds than with the fun of watching.
Standard monitoring guidance asks a lot of you:
- Check every three to four days.
- Keep each visit under a minute.
- Go in late morning or afternoon instead of early morning.
- Skip cold or rainy days.
- For bluebirds, stop opening the box once nestlings are about 12 to 13 days old, since they may leave the nest too early, and fledglings that leave too soon have low survival.
A camera box lets you follow every one of those rules without ever opening the door. With solar charging and a remote, you never have to walk out to the box during nesting season.
You'll see way more than someone peeking in once a week, the birds get less disturbance than even a careful check would cause, and that, to me, is where a camera box really pulls ahead of a plain wooden one.
A gentle heads-up, though. Watching a nest live means watching what really happens, and not every nest succeeds or every chick fledges. The camera shows you that part too.
Frequently Asked Questions
Which entrance hole should I fit? Pick the bird you're hoping for first, then match the hole. Use 1⅛" for chickadees, which also keeps House Sparrows out. Use 1½" for bluebirds and swallows, which keeps starlings out but not sparrows. And skip the 2" plate.
Will the camera keep birds away? I haven't found a study that tests camera boxes against plain ones. Most research using nest cameras hasn't reported problems, but very few studies actually test for harm, and one study of eagles found that adding cameras close to egg-laying lowered breeding success. So timing is the real concern. Get the camera installed before the season starts.
Is infrared safe for the birds? Yes! It's the setting to use while birds are nesting, because birds can't see or feel infrared. Keep white-light night vision off whenever the box is occupied.
How long before something nests in it? It could be the first spring. It could take two or three seasons. An empty first year is common enough that the big nest box programs specifically tell people not to worry about it.
Can I move the box if nothing uses it? Yes, between seasons, but never during an active nesting attempt. If a box sits empty for two seasons, take another look at the mount, the height, the direction, and whether there's a landing spot nearby before you blame the box.
Do I need a predator guard if it's on a pole? Yes. A pole is the best mount, but it isn't predator-proof on its own. The baffle is what makes a pole a great mount.
Which One Should You Get?
For most people, the standard Nest. It's the most affordable of the three, and its camera is right in line with the other two.
If you want to watch the comings and goings outside too, the Nest Duo. That second, outside camera is what you're paying extra for. The bigger 9000mAh battery and 5W panel also mean you'll worry about charging the least.

If you want a bamboo box you can mount on a pole, the Polygon. It's priced close to the Nest, and it mounts to a pole, a wall, or a tree (the Nest only hangs from a bracket).

Whichever one you choose, give the hole, the baffled pole, and the timing as much attention as the camera. Those are what get you a nest to watch.
