Culmen: 5.56 cm; tarsus: 7.197 cm; wing: 41.2 cm.
Total Length: 61 to 68 cm; Wingspan: 132 to 142 cm (Ref. 8812). Occupies the continental shelf; <80 km (Ref. 356). Scavengers; exhibits kleptoparasitism (Ref. 356). Opportunistic feeders that eat a wide variety of food. Based on stable isotope analysis (SIA) diet study of egg albumin, belongs to lower N signature group (based on ratios of stable isotopes of nitrogen and carbon) indicating a more planktivorous diet. Switch in diet from garbage to fish when chicks hatch for its higher nutritional content to assure higher fledging success. Early breeding and early egg-laying assures higher fledging success for this species. On the Farallon Islands, California, high nest failures recorded during ENSO (El Niño) events; severe events in 1982-1983 causing adult mortality. (Ref. 87784).
