Garden BirdWatch monitors the changing fortunes of birds and other garden wildlife through its network of 'citizen scientists'. Observations collected by BTO Garden BirdWatchers are analysed by BTO researchers and published in leading journals. BTO Garden BirdWatchers have charted the decline of the House Sparrow, the rise of the Woodpigeon, have discovered that urban birds get up later than their rural counterparts and have alerted conservationists to the impact of an emerging disease in Greenfinches.

Coal Tits are seen in more gardens during the winter, and are generally recorded by at least 40% of Garden BirdWatchers in November, when they are driven to garden bird feeders by cold weather. This year is turning out to be exceptional, with Coal Tits seen in an unprecedented 70% of gardens in November! In some years they are seen in many more gardens, and research using GBW data has shown that their presence is affected by seasonal availability of tree seed crops in the wider countryside.
