Smew - added to list, with only 0.9 records per year in the last ten years it falls below the rarity threshold for inclusion.
Sabine's Gull - amendment, only east coast records will be assessed. There is a regular population of over-summering passage birds in the Minch during the summer months. These account for the Broadford Bay records in strong northerlies, and passage to and from this area accounts for the other west coast and ferry route records.
Black Tern - amendment, all records now assessed including adults. Only 0.4 records/yr of adult Black Terns in the last ten years, and only 2.2 records/yr of juveniles.
