Black Rat

Rattus rattus

Type: Non-native Species | Status: Least Concern | Nativeness: Introduced


Widespread, omnivorous rodent commonly dispersed by people. Occurs in several colour morphs with fur ranging from black to tawny brown. Can be distinguished from the related brown rat (absent from Ascension Island) by its smaller ears, pointed face and a longer, hairless tail that is used for balance. Highly arboreal in wooded areas, preferring a diet of fruit and seeds where available, but will consume a wide range of food items, including predating small animals and eggs.
