BTO has been at the forefront of bird monitoring and research since we were founded in 1933, and since that time we have accrued a vast body of knowledge. Sharing our understanding of birds is an important part of our work, helping to invigorate and inform our vital volunteer base and inspire the next generation of ornithologists to tackle the conservation challenges of the future.
BTO strives to provide a deeper understanding of birds their behaviour. BirdFacts is a one-stop shop for data on British birds.Read our masterclass articles covering one aspect of ornithology in depth. Let us recommend what to read next in our book reviews.
A collaboration between 70 authors and 70 artists with a single goal: to raise funds for conservation work focused on our most at-risk birds.
Almost a third of UK bird species are in population free fall, and as a result our lives are diminished. Profits from the sale of this book will be donated to BTO and The Rare Breeding Birds Panel to further their work on Red-listed birds.
