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 Ground-Pine

The common ground pine, <em>Dendrolycopodium obscurum</em>, is a vascular plant belonging to the family Lycopodiaceae, a lineage of ancient clubmosses. This species is typically found across North America, with its known range encompassing Canada and the United States. As a lycophyte, <em>Dendrolycopodium obscurum</em> represents a deeply divergent lineage among land plants, distinct from mosses and ferns. The species typically grows in moist forested habitats, particularly in coniferous and mixed woodlands where humidity and leaf litter provide suitable conditions for its growth. Its upright, tree-like sporophylls give it the common name ground pine. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
