An Alaskan breeder migrating to the west coast of the Americas and islands of the Pacific, occasionally reaching New Zealand and Australia, where its close relative, Grey-tailed Tattler, is far commoner. Whilst the latter has reached Britain, Wandering Tattler is still unrecorded here, but there is a possibility of its turning up since the breeding area is very close to, and may extend into, W.Siberia. From there a reverse migration could bring it to Western Europe.
