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.

Collared Worm Salamander

The Collared Worm Salamander, known scientifically as <em>Oedipina collaris</em>, is a slender, elongated salamander belonging to the family Plethodontidae, the lungless salamanders. <em>Oedipina collaris</em> is characterised by its worm-like body form, extremely elongated trunk with many vertebrae, short limbs, and a long tail — morphological features that adapt the species for a burrowing or semi-fossorial lifestyle. As a plethodontid salamander, <em>Oedipina collaris</em> lacks lungs and respires entirely through its moist skin, making it highly dependent on humid environments. The species inhabits freshwater habitats, moist forests, and wetlands. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Worm Salamander is currently assessed as Data Deficient on the IUCN Red List, indicating that insufficient information is available to determine its conservation status accurately, and further research on the species' distribution and population trends is required.
