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.

爪哇禾雀

爪哇禾雀是东亚最受欢迎的笼鸟之一，外形优美，具有灰色羽毛、醒目的黑色头部、白色颊斑和鲜红色喙。原产于印度尼西亚的爪哇岛和巴厘岛，已被引入亚洲、非洲和美洲的许多地区。栖息于开阔草地、水稻田和农耕地，有时会危害水稻作物。由于笼鸟贸易的严重捕捉压力，在原产地被列为易危物种。
