BBRC

For modern interest the following two sub-pages list all species that currently have been recorded now on less than fifty occasions.

Where a locality is on the border of two counties, it becomes a dual-county record, but if a bird is found in one county then moves to another county it forms two records with only the first sighting counting in the totals.

Other dual-county records are due to counties working with the Watsonian county boundaries to keep consistent recording data with the neighbouring county adopting the 1974 goverment changes.

In 1985 'At sea' records were considered for the first time by the British Birds Rarities Committee (BBRC) and this area was referred to as the UK Economic Exclusion Zone. The boundaries are defined as 200 nautical miles (370 km), except where there is a median line between countries.

The Isle of Man during 2006 decided to have their own list, the Manx List, with BBRC carrying on in adjudicating on certain records and these Manx records appear in the BBRC statistics. However, BOURC have removed all Isle of Man firsts for Britain and added the next record as the new first.

I have decided to remove all the firsts for Britain that appeared in the Isle of Man from these listings as it is confusing the British List. The following species have had records removed:

Mourning Dove, Magnificent Frigatebird, White-throated Robin and Song Sparrow.
