Most nest boxes keep their secrets until the chicks have left. This one has a camera built in, so you can watch birds visiting and nesting from your phone without opening the box.

It is made from solid pine, carbonised to make it more weather resistant, with a metal-guarded entrance and a 180-degree magnetic door that opens for cleaning. The camera is listed as 4MP with night vision and a built-in microphone, and the box shows the nest's temperature and humidity live. A solar panel powers it, and the app sends a notification when a bird is detected. The listing also mentions AI identification of birds.

Worth knowing: The listing does not give the box's measurements or the entrance hole size, and the camera is described as 4MP in the text but 2K in the photos, so treat the figure as approximate. Check the app and Wi-Fi requirements before buying.
