Blagdon Lake Birds

Annotated Site Bird List

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. Some rare, very rare, and extremely rare species, will be linked to their own page (e.g. Pied-billed Grebe) which will provide more details about occurrences at the lake with dates, finders etc. These 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. 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) dated 29th November 2021 to adopt the nomenclature and order given by the International Ornithologists Congress (IOC) World Bird List (v12.2). This document follows the Tenth edition of the British List (BOU, 2022. Ibis 164: 860-910) and subsequent changes to the List included in BOURC Reports and announcements ( I've set out the list as follows:

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:

C1 – Naturalised introduced species - species that have occurred only as a result of introduction, e.g. Egyptian Goose Alopochen aegyptiaca.

C2 – Naturalised established species – species with established populations resulting from introduction by man, but which also occur in an apparently natural state, e.g. Greylag Goose Anser anser.

C3 – Naturalised re-established species – species with populations successfully re-established by man in areas of former occurrence, e.g. Red Kite Milvus milvus.

C4 – Naturalised feral species – domesticated species with populations established in the wild, e.g. Rock Pigeon (Dove)/Feral Pigeon Columba livia.

C5 – Vagrant naturalised species – species from established naturalised populations abroad, e.g. possibly some Ruddy Shelducks Tadorna ferruginea occurring in Britain. There are currently no species in category C5.

C6 – Former naturalised species - species formerly placed in C1 whose naturalised populations are either no longer self-sustaining or are considered extinct, e.g. Lady Amherst’s Pheasant Chrysolophus amherstiae.


A new Category F is currently being worked on by the BOU. It refers to records of bird species recorded between c. 16 000 BP (before present) to 1800.


Key to abundance (in a Blagdon Lake context):

Very rare - five or less records

Rare - less than annual; several years may pass between records

Very scarce - less than annual; typically recorded every two or three years

Scarce - very small numbers virtually every year (population counts 1 - 10)

Uncommon - low numbers recorded every year (population count 11 - 100)

Fairly common - occurs in reasonable numbers (population count 101 - 1000)

Common - occurs regularly in good numbers (population count 1001 - 10000)

Abundant - large numbers occur (population count 10000+)


Occurrence (in a Blagdon Lake context) :

R - Resident

SV - Summer Visitor

WV - Winter Visitor

PM - Passage Migrant

I - Introduction

F - Feral

V - Vagrant

WB - Storm/Wind-blown visitor

I - Irruptive

B - Breeder or suspected breeder in recent years
