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。

コブハクチョウ

世界で最もよく見られる白鳥であり最大の飛行鳥の一つで、コブハクチョウ(Cygnus olor)は最大 15 kg に達し、ヨーロッパとアジア全域の湖、川、沿岸湾に生息し、北アメリカとオーストラリアにも広く移入個体群があります。名前に反して、コブハクチョウはシューという音、うなり声、翅の風切り音など様々な音を出します。雄は縄張りを激しく防衛し、強力な翅の一撃で人間を傷つけたり犬を溺死させたりする能力があります。
