The BTO is an independent charitable research institute combining professional and citizen science aimed at using evidence of change in wildlife populations, particularly birds, to inform the public, opinion-formers and environmental policy- and decision-makers. Our impartiality enables our data and information to be used both by Government and NGO campaigners.

Over 40,000 volunteer birdwatchers, in partnership with professional research scientists, collect high quality monitoring data on birds and other wildlife. Membership subscriptions and donations help to secure our future. Proceeds from our organic cotton clothing and accessories go to funding our research.

All our t-shirts, tops, sweatshirts and tote bags are printed in the UK on premium quality 100% organic cotton made in an ethically accredited wind-powered factory.
