30 Years of BTO’s Garden BirdWatch

Santiago Cárdenas - Garden BirdWatch Survey Organiser, British Trust for Ornithology

For three decades, Garden BirdWatch has harnessed the power of citizen science to reveal how birds use our gardens and adapt to a changing world. From tracking population shifts to uncovering emerging threats, the project demonstrates how thousands of small observations can generate big scientific impact—and how people and birds remain at the heart of discovery.
