ワシミミズク

世界最大のフクロウ種であるワシミミズク(Bubo bubo)は翼開長最大1.9メートルに達し、ヨーロッパからアジアを経て中国にかけての岩石地帯、林縁、断崖に生息します。強力な爪を持つ静かな夜行性ハンターで、ウサギ、野ウサギ、キツネ、さらには他の猛禽類も獲物にします。深みのある響き渡る鳴き声は遠くまで届きます。歴史的に迫害されてきましたが、個体群は比較的安定しています。

gray wolf

最も広い分布域を持つ野生のイヌ科動物であるハイイロオオカミは、北アメリカからユーラシアにかけてのツンドラ、森林、草原などの多様な生息地に分布します。優位な繁殖ペアに率いられた家族単位の群れで生活する高度に社会的な動物です。キーストーン捕食者として獲物個体群を調整し、生態系の構造を根本的に形成することは、イエローストーンでの再導入により実証されています。かつて激しく迫害されましたが、多くの地域で個体群は回復しつつあります。
