Our updated and improved bird library covers all of the main species of bird which are seen in gardens, and both those that feed on food put out for them and those that just visit, or nest, such as the Swallow. We’ve combined our own considerable knowledge with facts and figures we’ve carefully researched, and frequently referenced the BTO’s up-to-date information and data on different species. We hope you find the library useful and informative, and please do contact us with any questions or suggestions on how we can improve it further.
