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.

Birds less reliant on gardens this spring

The Garden BirdWatch 2013 annual results show how much things can change in a year.

However, this year, so far, has painted a very different picture. Read more about it here.

Help monitor the health of garden wildlife
Dunnock with avian pox, by Dave Wragg


A new project to monitor the health of garden wildlife went live this summer. Called Garden Wildlife Health, the project allows you to submit observations of sick, dead and diseased wildlife and to (optionally) send carcasses to project vets for post mortem examination. You'll need to register with the project in order to access the online system (which you can do here). The project has also faciliated a small number of changes to our existing GBW Online system. Click here to find out what these changes are and what they mean to your weekly recording. Garden Wildlife Health is a joint project between the Institute of Zoology, BTO, Froglife and the RSPB.

Keep telling us about your unusual-looking garden birds
Blue Tit (Phil Littler)


The BTO Abnormal Plumage Survey and Big Garden Beak Watch projects are still on-going. If you see a bird with unusual-coloured plumage or a deformed beak in your garden, please let us know so that we can keep a record of these individuals. We are particularly interested in knowing where these birds are seen, the kinds of abnormalities that they experience and whether their behaviour differs from 'normal' individuals.
