The Mariana mallard was a resident allopatric population – in most respects a good species – apparently initially derived from mallard-Pacific black duck hybrids; [139] it became extinct in the late 20th century. [140] The Laysan duck is an insular relative of the mallard, with a very small and fluctuating population.
