[ 2026.04.01 ] April 7th is International Beaver Day
【Pitten ZOO】4月7日は「国際ビーバーDAY」です。
国際ビーバーデーは、2009年に「Wetlands & Wildlife (BWW) 」という組織が取り決めました。4月7日にした理由は、ビーバーを50年間研究したドロシー・リチャーズ（1894年〜1985年）の誕生日であるからということです。
どんな動物？
ビーバーは水中での生活に適応しており、水かきのある後ろ足を持ち、5本の指で物を掴むことができます。毛皮は水をはじき、内側に白い毛が生えており、水がしみるのを防ぎます。ビーバーは水辺の木を齧り倒して、泥や枯れ枝、水草、石などと組み合わせて大規模なダムを作り、中心部には巣を作ります。巣の出入り口を水面下につくることで、天敵の侵入を防ぎます。

Here's a natural English translation of the Japanese text, keeping the HTML tags intact:
International Beaver Day was established in 2009 by an organization called "Wetlands & Wildlife (BWW)." The reason for choosing April 7th is that it is the birthday of Dorothy Richards (1894–1985), who studied beavers for 50 years.
What kind of animal is it?
Beavers are adapted for life in the water, possessing webbed hind feet and five-fingered front paws that allow them to grasp objects. Their fur is water-repellent, with a layer of dense, white underfur that prevents water from penetrating. Beavers fell trees along waterways by gnawing at them and use the wood, along with mud, dead branches, aquatic plants, and stones, to build large dams. They create their lodges in the center of these dams, with underwater entrances to prevent predators from entering.
