🐦 📉 Once a familiar garden sight, Greenfinches have crashed in number since the early 2000's due to trichomonosis. BTO's Garden BirdWatch revealed the scale of the crisis - the sharp decline shows how fast wildlife can change, and how long-term monitoring is crucial for understanding these changes.
