Collared Petrel

The Collared Petrel, known scientifically as <em>Pterodroma brevipes</em>, is a seabird belonging to the family Procellariidae, the petrels and shearwaters. <em>Pterodroma brevipes</em> is a gadfly petrel characterised by its typically dark upperparts contrasting with paler underparts, and by a distinctive collar or partial collar pattern on the breast and neck. The species is highly pelagic, spending much of its life at sea and returning to land only to breed on remote oceanic islands. It is reported to occur in Norway according to available range data. Like other gadfly petrels, <em>Pterodroma brevipes</em> is a dynamic flier, capable of soaring at speed in strong winds. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Petrel is currently assessed as Vulnerable on the IUCN Red List, reflecting population concerns likely associated with threats at breeding colonies including introduced predators and habitat degradation.

Common Mountain Bush-cricket

The Common Mountain Bush-cricket (<em>Antaxius pedestris</em>) is an insect in the genus <em>Antaxius</em>, belonging to the family Tettigoniidae within the order Orthoptera. This species is classified as Least Concern on the IUCN Red List, suggesting its populations are currently stable. It is typically found across virtually all terrestrial and freshwater habitats within its range. As a bush-cricket, <em>Antaxius pedestris</em> belongs to a group characterized by long antennae, typically exceeding body length, and the ability to produce sound through stridulation — rubbing the wings together. Bush-crickets are generally omnivorous, feeding on plant material, small invertebrates, and occasionally other insects. The "mountain" designation in its common name reflects an association with elevated, rocky or montane habitats, which are typical for members of this genus in Europe. Detailed biological traits such as average lifespan, body dimensions, and weight are not widely documented for this species in available records. Further taxonomic and ecological research may better define the full distribution and habitat preferences of this species.
