Forming a superspecies with Eurasian and Australasian, this Bittern
was actually first described in England, the type specimen is from Devon, indicating that transatlantic vagrancy
was much commoner than the extreme rarity of today. However, it's not an easy bird to see in the USA, although I have
seen one all my photos were taken in the UK. The left bird is the latest record, at Carlton Marshes, in Suffolk in 2018.
