Collared Sparrowhawk

The Collared Sparrowhawk, known scientifically as <em>Accipiter cirrocephalus</em>, is a small bird of prey belonging to the family Accipitridae. As a member of the genus Accipiter, <em>Accipiter cirrocephalus</em> is characterised by its short, rounded wings and long tail, adaptations that enable agile manoeuvring through forest and woodland habitats while pursuing bird prey. The species typically inhabits forests, woodland, and forest edges, where it hunts small birds and occasionally insects. It is reported to occur in Norway according to available range data. Adult males of this species often display a distinctive rufous collar on the nape, which contributes to the species' common name. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Sparrowhawk is currently assessed as Least Concern on the IUCN Red List.

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.
