This following list is for general interest and shows all of the birds that are on the Bucks list but which have not been seen for some years. Sometimes for a great many years! This of course does not cover all of the species that have never turned up in the county. That would be a long list!
If you have been birding in the county for quite a few years then maybe you have seen a few of these. If not then it is maybe something to aim at!
While some of these are certainly possible (e.g. Rose-coloured Starling) others look extremely unlikely (e.g. Pallas’s Sandgrouse)! It also seems strange that a bird such as Puffin has been recorded 11 times in the county, but none since 1979!
The data was kindly compiled by Roger Bibby.
