Many species of North American landbird have been recorded in Great Britain as vagrants. Most occur in autumn; southwest England attracts is time than in autumn. Weather systems are thought to be the primary reason for the occurrence of birds in autumn; some birds seen in spring may simply be overshoots, although ship-assistance may also play a part.
