Rare Breeding Birds Panel

The Rare Breeding Birds Panel (RBBP) is an ornithological body which collects data on the breeding attempts and successes of the rarer species of birds breeding in the United Kingdom. It was created in 1968 as a subcommittee of the RSPB, with representation from the Nature Conservancy Council (NCC) and British Birds magazine.
