This Sub family differs from the last in having the tail square or rounded. With few exceptions its species are migratory, whereas the Forktails are invariably resident and whilst the Redstarts and Robins are essentially Palaearctic forms the Forktails are essentially tropical or sub-tropical. Both subfamilies, however, have much the same form of bill and wings; they have their feet and tarsi formed for running on the ground and the plumage of the nestlings is somewhat similar.
