Installing a basic nestbox camera gives an intimate view inside the nest and an immediate idea of how successful each brood has been. You need to connect this type of camera to your TV or computer by feeding the cables through an airbrick or windowframe air vent. Some even come complete with microphones so you can hear what is going on as well. Getting involved with projects such as the Big Garden Birdwatch (www. rspb.org.uk) and the BTO Nest Box Challenge (www. bto.org) means that your observations can contribute to science and help us to understand more about the changing populations of birds in the UK.
