Garden BirdWatch (GBW)
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.

New Garden BirdWatch interactive results pages
An astounding amount of data has been collected by thousands of volunteer BTO Garden BirdWatchers over the last twenty years but until recently only a fraction of it was available online. Now, thanks to recent developments in technology, we have been able to make more of it available in an interactive way on our results pages allowing the public to find out in greater detail how gardens are used by birds and other wildlife.
Is garden bird feeding driving evolutionary change in Blackcaps?
New research using data from Garden BirdWatch volunteers has revealed that bird food provided in British gardens has helped Blackcaps to rapidly evolve a successful new migration route. This is the first time that garden bird feeding has been shown to affect large-scale bird distributions.
