Low pressure waves that contributed to the formation of Hurricane Wilma in the western Caribbean produced westerly winds in the central Caribbean and Puerto Rico during the second week of October, 2005. On October 12 and for the following two weeks Swainson’s Thrush (Catharus ustulatus, six locations) and Veery (C. fuscescens, one location) were reported from the island. These species usually migrate through Central America and the central Caribbean and appear not to have been recorded before in Puerto Rico. The hurricane season overlaps the autumnal migration. Increase in cyclonic activity with local wind direction dependent on the location of centers of low pressure may increase vagrancy.
