A hybrid or cross between a falcon and a peregrine, or a rare bird combining falcon and peregrine characteristics.
Compound word: falcon plus peregrine. This neologism describes mixed-species birds, though such hybrids are extremely rare in nature.
Falcoperegrine hybrids almost never happen in nature because falcons are so picky about mates—but when they do, they create birds that might be even faster than their parents!
