Among the birds that came to Southeast Farallon Island in a spectacular migrational wave on 12 September 1974 was a Dotterel (Eudromias morinellus). The number of shorebird species on the island had increased from 5 the previous day to 13, and the number of other migrant species from 14 to 59. The island, located 43 km west of San Francisco, California, is visited regularly in the spring and fall by migrant birds.
