Coastal Silver-stiletto

Coastal silver stiletto (Acrosathe annulata) is a slender robber fly in the family Therevidae, native to northwestern Europe, including the United Kingdom, France, the Netherlands, Belgium, and Scandinavia. Adults are found on coastal sand dunes and sandy heathland, where they perch on bare sand to ambush small flying insects. Stiletto flies in the family Therevidae are characterised by a slender body, long pointed abdomen, and predatory habits; adults prey on a variety of small dipterans and other flying insects during warm, sunny periods. Larvae develop in sandy soil, where they are also predatory, feeding on other invertebrate larvae. Acrosathe annulata is a habitat specialist restricted to open, sandy coastal habitats with sparse vegetation—environments that have declined substantially across northwestern Europe due to dune stabilisation, recreational disturbance, and the cessation of traditional dune management. The IUCN lists it as Least Concern, though regional conservation bodies in the United Kingdom have flagged population declines. It is considered an indicator of high-quality coastal sand dune habitats and is monitored through national invertebrate surveys.

águia-real

Entre as aves de rapina mais poderosas e amplamente distribuídas do mundo, as águias-reais têm envergaduras que chegam a 2,2 metros e habitam terrenos montanhosos em todo o Hemisfério Norte. Caçadoras aéreas supremas, usam voo planado e mergulhos íngremes a velocidades superiores a 200 km/h para capturar coelhos, lebres, esquilos terrestres e ocasionalmente cervos jovens e raposas. Em muitas culturas, foram centrais nas tradições de falcoaria que abrangem milênios.
