Modern records
This is a very rare migrant to the UK and in most years is not recorded at all. In fact, fewer than 20 individuals are thought to have been seen in the UK since the 1950s and it may now be completely absent from the country. From Jenyns’ accounts it appears to have been similarly rare 200 years ago, as he talks about specific individual specimens being collected, rather than localities where the species was found in any number.
