This small yellowish warbler is a very rare autumn visitor from North America, where it is a common breeding species across much of Canada.

Blackpoll Warbler is the most regular North American warbler to be found in the UK, but is still a major prize for any birder lucky enough to stumble across one. Records average one or two per year, with the Isles of Scilly by far the most favoured place for them. Most are found in October.
