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.

Garden BirdWatch celebrates 20 years
This year we're celebrating 20 years of GBW and we'd like to thank our dedicated supporters - without them there wouldn't be a survey. In the last 20 years:
- GBW volunteers have contributed an astonishing 7.3 million hours of their time submitting just under 100 million observations.
- 481 different species have been recorded from several taxa.
- 30,271 gardens have contributed at least one week of data.
- An average of one scientific paper has been produced per year including several investigating the decline of the UK's House Sparrow population, which was first discovered through the BTO's garden-based data.
Cold weather boost to garden bird numbers
Until recently, it looked like garden bird numbers were going to stay as low as they were during the winter of 2013/14. However, with large parts of the country now experiencing frosts and snow, preliminary Garden BirdWatch results show that our garden birds are moving back in.
Good year for Robins, Santa included
Thanks to a relatively mild start to the year, a bumper breeding season, and plenty of food available in the wider countryside this autumn, it’s been a good year for Robins, including the extraordinary Santa Robin! First brought to our attention in 2012, this remarkable leucistic bird (with a Santa beard) has now survived at least three winters in Derbyshire.
