Two bird-box cameras, from the maker pages

This is an explainer, not a review. We have not filmed a brood with either camera. The figures are copied, in plainer words, from the maker pages opened on 14 November 2026. The links go to those pages. They are not affiliate links: the Green Feathers and Birdfy programmes have not been joined. Amazon listings were not added, because the untagged Amazon pages did not open.

We haven't tested this. Figures are as the maker states them (checked 14 November 2026).

What to decide before the spec sheet

The hole, if the product is a whole box, has to suit the bird. The BTO’s make-a-box table is 25 mm, 28 mm and 32 mm for the small hole-nesters, and the putting-up page adds 45 mm for starlings. A camera you drop into your own box leaves that choice with you. A camera sold inside a box with one fixed hole does not. Read hole sizes beside the entrance figure below.

Power is the other split. A camera that needs a 12 V cable has to be near a supply you can run before the birds arrive. A battery and a solar panel avoid that cable, and still need enough winter light to keep up. Neither page we opened states a guaranteed Wi-Fi range in metres for these two models. Do not trust a range we did not read. Stand in the garden with a phone and see whether your own network is usable there. The Green Feathers page suggests you want download speeds of at least 40 Mbps.

Once birds are building, leave the box alone. The legal note is in cleaning a nest box.

Green Feathers WiFi HD camera

The page is the WiFi bird box camera. The option priced below is the camera for a bird box, product code GFWF3GB-B01, not one of the packs that include a wooden box.

The maker states:

• 2 megapixel, 1/3 inch CMOS sensor, 2.8 mm lens.
• Main stream 1920×1080, sub-stream 640×480, 15 frames per second, H.264.
• Built-in microphone. The speaker is described as for setup only.
• microSD card up to 128 GB, not included. Recording can be continuous or on motion. They say recording uses about 2 GB an hour, so a 64 GB card is about 32 hours and a 128 GB card about 64 hours.
• Infrared LEDs for night vision, described as a 1 m range on this model.
• Wi-Fi on both 2.4 GHz and 5 GHz. They say cameras bought after October 2024 are dual-band.
• Power is DC 12 V on a 2.1 mm jack. About 1.5 W with infrared off and 1.7 W with it on. Operating range −20°C to +50°C. The camera body is 44×44×33 mm.
• IP54, and a separate sentence that this camera is not waterproof.
• Apps: iOS 10 or later, Android 5 or later. ONVIF is listed.

The spec block does not mention a subscription. Storage is the card in the camera. We are not upgrading that silence into a promise that a future app will stay free.

The page showed £134.10, next to “Save 10%”, against £149.00, for the UK camera-only option. Packs that include a box were listed higher (a starter pack at £158.00 against £197.50, a complete pack at £191.20 against £239.00). Those are the figures on the page that day, not a price we negotiated.

You mount this in a box you already own, so the entrance hole is yours to match to the BTO table. Run the 12 V supply before February, when the BTO says pairs start looking.

Birdfy Nest Wood

The page is the Birdfy Nest Wood on the UK shop.

The maker states:

• Resolution 2K, 2304×1296. Night vision is white light or infrared.
• 2.4 GHz Wi-Fi only. The page’s own “why 2.4 GHz” line is that it has more range through walls than 5 GHz. No metre figure is given.
• Battery 5,200 mAh, charged at DC 5 V / 1.5 A. A 2 W solar panel is built in.
• Entrance 38 mm (they also write 1.5 inches), and “no guards”.
• Two-way audio, Bluetooth pairing, a passive infrared motion sensor.
• Species recognition described as “lifetime free”.
• MicroSD replay: not available.
• Cloud storage described as free for the whole breeding cycle, plus 30 days after the birds leave so you can download clips.
• Working temperature −10°C to 45°C. IP65. Weight about 1.38 kg. Body about 210×207×320 mm. Material given as Cunninghamia plus ABS. Warranty 2 years.

The selling price shown was £129.99. The page also showed a compare-at figure of £239.99. That higher number is not a second price you should expect to pay; it is the compare-at figure on the page.

The 38 mm hole is wider than 25, 28 and 32 mm. The BTO buying page treats 32 mm as the general small-bird hole and does not list 38 mm. We will not guess which species will use it. If you specifically want blue tits, this entrance is not the 25 or 28 mm those BTO pages discuss.

There is no microSD playback on the spec, so the archive they describe is the free cloud window, not a card you own. If that window matters to you, read the current wording on their page before you rely on it.

Choosing between them

The Green Feathers camera leaves the box, the hole and the power cable in your hands, and records to a card. The Birdfy is a whole box with a solar battery, a 38 mm hole, and cloud storage instead of a card. Neither link earns this site a fee. Prices will move.

If the camera can see a neighbour’s garden or the pavement, read garden cameras and privacy.

Do these cameras need a subscription?

The Green Feathers spec we read does not list one; it lists a microSD card. Birdfy describes cloud storage as free for the breeding cycle plus 30 days, and species recognition as lifetime free, and lists microSD replay as unavailable. Check the live pages. We have not signed up for either app.

Which has the longer Wi-Fi range?

Neither of these two pages gave a distance we can quote. Test your own signal where the box will go.

Can I open the box in April to move the camera?

Not if a nest is being built or is in use. That is the England and Wales offence described in the cleaning guide, and the BTO’s advice is to have the box ready before birds prospect in late February.
