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 Data Entry System for Garden BirdWatch

We've just launched a brand new data entry system. The new system is designed to make entering your weekly records easier by phone and tablet. In addition to this, we're now asking whether or not you'd record other wildlife if you saw it. This is a small but important change. You can find out more about the importance of this in an article by Kate Risely. To make this easier you are able to set your preferences by clicking 'edit my details', which is just below your GBW number on the right-hand side of the screen. 

Tawny Owl by Howard Stockdale/BTO

Heard an owl?

Are there Tawny Owls calling in your area? By listening out for them in your garden or nearby green space you could help us to understand their calling behaviour and distribution, and to discover the impact of urbanisation and artificial lighting. 

It's easy to take part - just listen for 20 minutes during at least one evening between now and 31 March 2019. You can listen from your garden, local park or woodland. You can even listen whilst lying in bed with the window open! All information is valuable, even zero counts.
