Black Rat (Rattus rattus)

August 24, 2017 by

Pennsylvania Counties for Black Rat

Common Name: Black Rat

Scientific Name: Rattus rattus

Habitat: In close association with humans near seaports.

Diet: Omnivorous—probably feeding on all types of organic material.

Interesting Facts:
This species is thought to have been extirpated from (forced out of) the Commonwealth by pressure from the more aggressive Norway rat. Although some individuals may continue to find their way to coastal seaports such as Philadelphia via incoming ships, it is unlikely that populations will be successfully re-established.
