The Tree Sparrow (Spizella arborea) has generally been considered a rare winter visitant in California, most frequently found in the northeastern portion of the state (Grinnell and Miller, Pac. Coast Avif. No. 27, 1944). McCaskie (Western Birds 4:65–70, 1973) summarized all California records and demonstrated that the Tree Sparrow was somewhat more abundant and wide-ranging than previously realized, listing five spring records (May and June) from the Farallon Islands and one on board a ship farther south. He suggested that a record for 14 June might be the latest south of the Canadian border. More recent spring records from the Farallon Islands (American Birds 29:906, 1975; 31:1045, 1977; 31:1187, 1977) extend the latest date to 26 June.
