Joining the dots using bird and butterfly data

By working with Butterfly Conservation (BC), we have been able to test the extent that sites with a greater abundance of birds also support other wildlife, in this case, butterflies and so see the effect of environmental change on a relatively small scale. To celebrate our collaboration we have a unique 2 for 1 special offer where you can support the work of the BTO and BC by joining both for just £30.

Cuckoo by Edmund Fellowes

Three Cuckoos across the desert

During the early hours of the 13 April, locations recieved from Stanley and Derek showed that they have joined Dudley in successfully making the crossing of the formidable Sahara Desert. We now have two birds in Europe and one in Morocco. Follow our Cuckoo tracking project.

Garden BirdWatch celebrates 20 years

This year we're celebrating 20 years of Garden BirdWatch 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. From this 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.

House Martin by Peter Dedicoat

Select a square for the House Martin Survey

We’re looking for volunteers to take on a 1-km square for the new House Martin Survey this year. Just three visits are required from late May onwards. Have a look at the available random squares to see if there is a square near you. The survey requires you to find and map House Martin colonies in the square and to count occupied nests.
