The recording area
The Bristol region follows cover the following four ‘unitary authorities’:
- South Gloucestershire (SG)
- Bristol (BR)
- Bath and North-east Somerset (BA)
- North Somerset (NS).
The area covered by these four administrative units corresponds almost exactly to the old county of Avon, which ceased to exist on April 1st 1996.
Submitting your records
Records should supply details of the species, the number of individuals, the date seen, the site; with as accurate a grid reference as possible and any other relevant information.
Records can be submitted in a number of ways:
- to the BOC, either monthly by email to or via the ‘Contact us’ page on this website.
- daily to the AVON BIRDS blogspot – email
- by inputting them to the BTOs BirdTrack website
- annually, before the end of January, by e-mail to . Ideally they should be as an Excel spreadsheet or a Word table, with each record on a separate line and dates in a dd/mm/yyyy format.
- BTO WeBS counts and other BTO and local survey data are automatically made available to us.
All records are kept – they are stored by Bristol Regional Environmental Records Centre (BRERC) in Bristol so they are properly archived and can be used for conservation and scientific enquiries, sometimes of considerable importance to the bird-life of the area.

Species for which a description is required
For the locally rare species and subspecies set out below we require a description (reasons for a description) that confirms the plumage, and other details noted in arriving at the identification. The figure in brackets is the number of live individuals recorded between 1983 and 2017. Species without a figure, have not yet been seen in Avon or have only recently been added to the list.
The figure preceding the brackets refers to the conditions when a description is required:
