The Rare Breeding Birds Panel (RBBP) was founded 50 years ago this month. It uses data, mostly collected by volunteers, to track the fortunes of around 100 of the UK's rarest breeding species, including Golden Eagle, Crane and Turtle Dove. The Panel's work informs a wide range of conservation and monitoring work, including the reintroduction of Red Kite and White-tailed Eagle, and assessments of Sites of Special Scientific Interest and Special Protection Areas.
