ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

Chocolate Boobook

The Chocolate Boobook (Ninox randi) is a small to medium-sized owl in the family Strigidae, belonging to the diverse Australasian genus Ninox — the hawk-owls — which ranges from South Asia through Southeast Asia to Australia and the Pacific. This species is endemic to the Philippine archipelago, where it is found on the islands of Mindanao, Basilan, Leyte, Samar, and several adjacent smaller islands. As its name suggests, it is distinguished by its rich, warm brown plumage overall, with spotted or streaked underparts. The chocolate boobook inhabits lowland and foothill forest, including primary and mature secondary growth, where it forages nocturnally for large invertebrates, small vertebrates, and possibly small birds. Like other Ninox owls, it produces characteristic hooting or barking calls audible at night in its forest habitat. The IUCN classifies the Chocolate Boobook as Near Threatened, reflecting ongoing deforestation and habitat degradation across the Philippine lowlands, where forest has been extensively cleared for agriculture and logging over the past century. The Philippines is a global biodiversity hotspot with high endemism and severe ongoing habitat loss, making many forest-dependent species including this owl vulnerable to further population decline if conservation measures are not strengthened.
