The southern extent of the known breeding range of the Horned Puffin is Forrester Island, Alaska. They have not yet been found breeding in British Columbia. However, in 1973 Sealy and Wilson (Syesis 6:51-55) reported that Horned Puffins (Fratercula corniculata) were becoming a regular winter and spring visitant to the coasts of British Columbia. Later, Hoffman, Elliott and Scott (Western Birds 6:87-94, 1975) reported that the species had been sighted along the Oregon and California coasts in May, June and July.
