Atlantische Bergschrecke

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.

Flussseeschwalbe

Common Tern (Sterna hirundo) is classified as Endangered (EN) on the IUCN Red List. At high risk of extinction in the wild, with significant population decline and ongoing threats to survival.
