Birds List [2018 revision]

A list of the birds reliably recorded to date

Families, species and sub-species names are listed with links to species pages (note that not all of these have been published yet, with others being updated and improved). For those species that have been designated as 'extremely rare' (see abundance key below), I have included the year of the record(s) in the list for quick reference. If you wish to see more information, including dates of 'very rare' and some 'rare' species records, visit the respective species account. Records marked with an asterisk have probably not been seen by, or considered, or accepted by the respective local Recorder's committee. Having said that, it is equally possible that some may have been rejected by the local Recorders' committees (Somerset as was, or, Avon as is), or the British Birds Rarities Committee (BBRC). Unfortunately, decisions are often not published, which leads to confusion. At some point, I will try and clear up decisions with those listed records for the sake of clarity.

This revision of the list follows the decision made by the British Ornithologists Union (BOU) to adopt the nomenclature and order given by the International Ornithologists Congress (IOC) World Bird List from 1st January 2018. I've set out the list as follows:

IOU World Bird List Order

IOU World Bird List Family

Some, mainly rare, very rare and extremely rare species, are linked to their own page which will provide more details about occurrences at the lake with dates, finders etc. This should be more or less up to date, and will be added to accordingly. In time, I hope to complete species accounts for all birds on the list. If you can provide any information to add to my database of bird sightings at the lake I'd be really grateful. I plan to publish a paper in due course and any information that is provided will be duly acknowledged.

Categories A, B & C

Species in Categories A, B and C form the British List.

Species in Category A have been recorded in an apparently natural state at least once since 1 January 1950.

Species in Category B have been recorded in an apparently natural state at least once between 1 January 1800 and 31 December 1949, but have not been recorded subsequently.

Species in Category C, although introduced, now derive from the resulting self-sustaining populations:

Sub-total 250 spp.

Category D

Species that would otherwise appear in Category A except that there is reasonable doubt that they have ever occurred in a natural state. Species placed only in Category D form no part of the British List, and are not included in the species totals.

Category E

Species that have been recorded as introductions, human-assisted transportees or escapees from captivity, and whose breeding populations (if any) are thought not to be self-sustaining. Species in Category E that have bred in the wild in Britain are designated as E*. Category E species form no part of the British List (unless already included within Categories A, B or C).

Note 1: Some, or all, of the Bar-headed Geese recorded locally were Bar-headed x Snow Goose hybrids. It would be worth reviewing photos of those reported where they're available.

Sub-total 19 spp.
