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。

Common Speckled Bush-cricket

<em>Leptophyes punctatissima</em>, commonly known as the common speckled bush cricket, is a medium-sized bush cricket in the family Tettigoniidae, widespread across Europe and parts of western Asia. This species typically inhabits hedgerows, woodland edges, bramble patches, tall herbaceous vegetation, and gardens, where dense leafy cover provides both shelter and food. It is distributed from the British Isles and Scandinavia south through continental Europe to the Mediterranean basin and eastward into parts of the Middle East. Classified as Near Threatened on the IUCN Red List, <em>Leptophyes punctatissima</em> faces pressures from agricultural intensification, loss of hedgerow habitats, and changes in vegetation management. The species is primarily herbivorous, typically feeding on the leaves and flowers of a variety of plants including bramble, raspberry, and other soft-leaved shrubs and herbs. Adults are typically green with fine black speckles, and females possess a distinctively long, curved ovipositor used to deposit eggs into plant tissue. Calling songs are produced at ultrasonic frequencies largely inaudible to humans. Biological traits such as average lifespan in years, body length measurements, and body weight remain poorly documented at the population level, though adults are typically present from midsummer through autumn before dying off as temperatures drop.
