common brushtail possum

The common brushtail possum (<em>Trichosurus vulpecula</em>) is a medium-sized marsupial with occurrences recorded in the Czech Republic, New Zealand, Norway, and Sweden, though it is native to Australia and was introduced to New Zealand. This species typically inhabits diverse terrestrial and aquatic environments, including eucalyptus woodlands, urban parks, and gardens. The common brushtail possum has not been formally evaluated on the IUCN Red List. As a member of the family Phalangeridae, it is recognized by its bushy black tail, large ears, and silvery gray fur. The species often forages nocturnally, feeding on leaves, fruits, flowers, and occasionally invertebrates. In New Zealand, where it was introduced in the 19th century, the common brushtail possum has become a significant ecological pest, threatening native vegetation and bird species. It typically shelters in tree hollows, roof spaces, or dense vegetation during the day. Biological traits of this species remain poorly documented in the scientific literature.
