					Total Length:  127 to 178 cm; Wingspan:   244 to 299 cm (Ref. 8812). Coastal; <50 km (Ref. 356).  Migration route from northern and central Canada and the US unto the southern states of Baja and into the Gulf of Mexico.  Grows a bill horn in preparation for courtship which is shed after incubation commences. Pre-pairing procedure involving complex communal interactions, chases, and terrestrial, aquatic and aerial processions. Extra-pair copulation rare.  Embryos are exceptionally known to elicit parental incubation behavior by vocalizing. Mortality rate of immature birds is 41% in the first year. The pesticide DDT in the 1960s caused egg-shell thinning such that they broke during incubation  (Ref. 87784). Displays surface seizing (Ref. 356).
