The Flammulated Owl (Otus flammeolus) is a widespread migratory species which breeds in mountains west of the Great Plains from southern British Columbia (Godfrey 1966; Cannings 1982) south to Veracruz, Mexico (AOU 1983). A number of recent papers provide a review of the distribution, habitat affinities, and seasonal occurrences of Flammulated Owls in California (Johnson and Russell 1962; Winter 1974, 1979; Marcot and Hill 1980; Bloom 1983); however, there is still much to be learned about the migratory habits of this species.
