The word perilanner is a falconer's term for a hybrid between a peregrine falcon and a lanner falcon.^[1] It is larger and faster than a lanner, but does not fly as far as a peregrine and thus is less likely to fly far away and become lost. As a rule, the peregrine is the father and the lanner is the mother. Perilanners are a popular choice for modern falconers.
