Synonyms—Strigiceps uliginosus; Brachyotus palustris; Brachyotus cas-

small numbers on extensive marshy areas, as those around San Diego and San 
Francisco bays. Reeorded definitely as breeding at Los Bafhos, Merced County 
(Bishop, Condor, vir, 1906, p. 29), and New Hope, Fresno County (Tyler, Pac.
