Habitat selection and distribution of the Flammulated Owl (Otus flammeolus) in California is incompletely known. Grinnell and Miller (1944) noted only two locations in the northeastern part of the state. Johnson and Russell (1962) provided records of at least 33 individuals in seven additional northeastern California locations.
The most comprehensive survey to date has been by Winter (1974), reporting 59 specimen and 89 sight records since 1860 in California. Two of the records Winter reported for the northwestern portion of the state are from Humboldt County, and five are from Trinity County.
