the peregrine falcon is derived from the time of king john i of mann. in 1405, he was granted the isle of man, on condition he paid homage to king henry iv of england, and gave two peregrine falcons to him and every future english king their coronation day. the descendants of john i ruled the isle of man until king george iii of great britain as the lords of mann. the presentation of falcons continued on, until the coronation of king george iv, in 1822.
