British Trust for Ornithology (BTO)

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. Their impartiality enables data and information to be used both by Government and NGO campaigners.
 
Their long-term monitoring data on the status of UK birds sets the standard worldwide for understanding the effects of environmental change on wildlife. Over 40,000 volunteer birdwatchers, in partnership with professional research scientists, collect high quality monitoring data on birds and other wildlife. The combination of professional ecologists, long-term datasets some in excess of 50 years, and volunteers participating all over the country gives the BTO a unique, impartial and knowledgeable voice in nature conservation.
