Mega’s (non-passerines)
Records for species are in order of date, then in alphabetical order of county, locality.
After the scientific name and author of the species there are in parenthesis two numbers, the first figure denoting the number of records up to 31st December 1949, with the second figure for those recorded from 1950 to date, in compliance with Europe. The records prior to 1950 can be found in detail elsewhere.
All records are referenced in parenthesis. Where WIP is used for referencing it is because the record is taken from the BBRCs Work in Progress file to keep this web site as up to date as possible.
The four seasons are classed: Winter (Dec. - Feb.), Spring (Mar. - May), Summer (Jun. - Aug.) and Autumn (Sep. - Nov.).
Taxonomic order follows AviList Core Team. 2025. AviList: The Global Avian Checklist, v2025, displaying the Family followed by indented species. Species with trinomials are accepted BOURC sub-species.
Anatidae Ducks, Swans and Geese
At the 2020 BBRC AGM a stricter set of criteria for the acceptance of rare ducks and geese was agreed. The following is reproduced from British Birds, May 2021: “They must be seen to be fully-winged; be seen to be unringed (or have been ringed in the wild in its natural range); behave as a wild bird; be at a location frequented by wild ducks; arrive at an appropriate time of year for a vagrant, not linger through the summer; be with an appropriate carrier species (applies for Eurasian ducks and all geese)” [BBRC News May 2021].
