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.
