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 Moonwort

Common Moonwort (<em>Botrychium lunaria</em>) is a small fern in the genus <em>Botrychium</em>, family Ophioglossaceae. It is distributed across Asia, Europe, and North America, with confirmed presence in Belgium, Denmark, Norway, Portugal, and Sweden, as well as Taiwan and the United States. The species is typically found in moist, shaded forest floors and tropical canopies. Common Moonwort is currently classified as Endangered on the IUCN Red List, indicating that it faces significant conservation challenges across its range. Its distinctive frond is divided into two parts: a sterile fan-shaped leaf portion with rounded lobes resembling a crescent moon, and a fertile spike bearing spore-bearing structures. As a fern ally rather than a flowering plant, it reproduces via spores rather than seeds. The species is associated with stable, undisturbed habitats including ancient grasslands, upland heaths, and rocky slopes. Its sensitivity to habitat disturbance and changes in land management are thought to contribute to population declines. Specific biological measurements such as lifespan and dimensions are not documented in available records.
