Guacamayo Frenticastaño

La guacamaya frenticastaña es una guacamaya mediana de los bosques tropicales de América Central y del Sur, desde el sur de México hasta Bolivia y Brasil. Tiene plumaje predominantemente verde con la frente castaña, manchas rojas en los hombros y plumas de vuelo azules. La más pequeña de las verdaderas guacamayas, habita bordes de bosques, sabanas y bosques secundarios y con frecuencia ataca cultivos, lo que la hace localmente impopular entre los agricultores. Son populares aves de aviario, pero las poblaciones silvestres enfrentan presión por la captura y la deforestación.

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.
