The official Manx List of wild birds is maintained by the Manx Bird Records Committee (MBRC), a sub-committee of the Manx Bird Club formerly Manx Ornithological Society (MOS). The list documents all species deemed to have occurred in a wild state in the Isle of Man.

Records of scarce and rare Manx species as well as rare Manx breeding species are reviewed by MBRC in the first instance. Those supported by adequate proof of identification and circumstances, and hence deemed to have been proven, are added to the Manx List. Records of species that are rare in the wider context of the British Isles are scrutinised by the British Birds Rarities Committee (BBRC), while records of rare breeding birds are notified to the Rare Breeding Birds Panel (RBBP).
