Pacific Black x Mallard ducks

Pacific Black ducks had been recorded as stragglers since the 1850's at Lord Howe Island, and there is a record of ducks breeding here in 1941. But in the 1970's a small number of Pacific Black ducks crossed with American Mallard ducks colonised the island and established a breeding population. Numbers fluctuated with breeding seasons, predators (Currawongs and owls) and food supply. In 2007 the LHI Board had investigations done into the status of the duck populations on the island, and declared they were all more feral Mallard than native Pacific Black duck, and have begun an extermination program.
