Pazifische Ratte
The introduced Australian common brushtail possum ("Trichosurus vulpecula") and introduced species of rats – mainly the ship or black rat ("Rattus rattus") but also the kiore or Polynesian rat ("Rattus exulans") and brown rat ("Rattus norvegicus") – have significantly reduced the amount of fruit available for pigeons and other native birds, and also prey on eggs and nestlings.
