カソワリ (Cassowary) は、オーストラリア北東部1500〜2500 ほど生息している他、インドネシア、パプアニューギニアなどの熱帯雨林地域に見られる珍しい鳥です。


オーストラリアに生息するカソワリは 『Southern cassowary (別名 double-wattled cassowary) 』と呼ばれる種類です。




食性は果実を中心とした雑食性で、森林の林床で落ちている果実を採餌し、大きな種子を持った果実でもついばんで丸呑みします。1日に5kgのえさを必要とし、そのために1日に20kmも歩き回ります。ヒクイドリ属の鳥には、他の動物には毒性をしめすキョウチクトウ科ミフクラギ属コバナミフクラギ(学名: Cerbera floribunda; 英語: Cassowary plum)という植物の果実を安全に消化する能力があります。果実と一緒に飲みこまれた種子は糞と共に排出される事で芽吹き、ヒクイドリ属の鳥の移動とともに広範囲に種子が散布されるので、果実食の習性は彼等が生きる森林を維持するのに重要な役割を担っています。カタツムリや小型の哺乳類の死骸や、菌類や昆虫類、小さな甲殻類も捕食します。
