>Cassowaries have a reputation for being dangerous to people and domestic animals. During World War II American and Australian troops stationed in New Guinea were warned to steer clear of them. In his book Living Birds of the World from 1958, ornithologist Thomas E. Gilliard wrote: "The inner or second of the three toes is fitted with a long, straight, murderous nail which can sever an arm or eviscerate an abdomen with ease. There are many records of natives being killed by this bird."[19]
>This assessment of the danger posed by cassowaries has been repeated in print by authors including Gregory S. Paul (1988)[20] and Jared Diamond (1997).[21] Of 221 attacks studied in 2003, 150 were against humans. 75% of these were from cassowaries that had been fed by people. 71% of the time the bird chased or charged the victim. 15% of the time they kicked. Of the attacks, 73% involved the birds expecting or snatching food, 5% involved defending natural food sources, 15% involved defending themselves from attack, 7% involved defending their chicks or eggs. The 150 attacks included at least one human death.[22]
