Second, its two predators are both easily frightened by whistles, because hermid ibis vulnerable period are preety short, with the human guard with whistles, hermid ibis can easily pass this dangerous period. Third, Although it cannot learn the migration from its parents under the way of captive, but human can trained it to learn the migrate route. By make it follow a small airplane, it can be trained.
