Mainland islands are sites on larger islands where predators have been removed and excluded through fencing, or are permanently controlled in order to provide safe breeding locations for threatened island species. We do this by protecting habitat, removing invasive species, and then attracting or translocating bird species into these areas.
Translocation is the moving of a species from one location to another to start a new colony. We move chicks of imperiled bird species before they have imprinted on their birth colony, and hand-raise them at their new colony (within the predator proof fences) until they are adults. They will then imprint on their new colony and return to breed as adults and create a new colony.
