Grinnell and Miller (1944) considered the Tree Sparrow (Spizella arborea) a rare winter visitor to California, indicating it occurred chiefly in the northeastern plateau region. However, they cite but two records for that region: an undated specimen from Fort Cook, Shasta County, and two specimens, along with others seen, from the area at the north end of Honey Lake, Lassen County, in January and February 1936. In addition they refer to a specimen taken in Pacific Grove, Monterey County, on 13 October 1916, and another specimen taken in Riverside, Riverside County, on 7 February 1888, along with a doubtful record from Butte County and an erroneous record from Alameda County.
