The UK400 Club has updated its list for Britain and Ireland. As a result, BUBO Listing has updated the underlying base list for the UK400 authority.
The UK400 Club now recognises 646 species, including four species previously listed as 'provisional' by BUBO Listing - Glaucous-winged Gull, Long-billed Murrelet, Olive-tree Warbler and Canada Warbler - as well as Masked Booby and Atlantic Yellow-nosed Albatross.
Conversely, the new UK400 Club list no longer includes Brown Skua or Eastern Orphean Warbler.
