Suspected to be an Acadian flycatcher from North America, the historic landing on the beach at Dungeness in Kent is about to spark the biggest mass gathering of twitchers in years.
Thousands of twitchers are expected to descend on the south easterly tip of the country overnight to catch a sight of the small robin-sized bird that should, by rights, be basking in the tropical forests of Panama or Colombia.
Somehow it has been caught up in a fast-moving Atlantic weather system that has taken it from its nesting grounds in eastern USA to the famous gravel headland overlooking the English Channel.
Dungeness is renowned for its huge nuclear plant as well as being the backdrop of music videos and atmospheric crime dramas.
