The scientific culture of the 19th century introduced some "scientific" rationalizations for the myth's origins, by suggesting that the origin of the [[Mythology|myth]] of the roc may lie in embellishments of the often-witnessed power of the eagle that could carry away a newborn lamb. 19世紀の科学文化は、ロック鳥の神話の起源は、生まれたばかりの子羊を運び去ることがしばしば目撃される、鷲の能力を誇張したものではないかとし、神話の起源に対するいくつかの「科学的」合理的な推論を示した。 In 1863, [[Giovanni Giuseppe Bianconi|Bianconi]] suggested the roc was a [[Bird of prey|raptor]] (Hawkins and Goodman, 2003: 1031). Recently a giant [[subfossil]] eagle, the [[Malagasy crowned eagle]], identified from [[Madagascar]] was actually implicated as a top bird [[predator]] of the island, whose [[megafauna]] once included giant [[lemur]]s and [[Malagasy hippopotamus|pygmy hippopotamuses]].<ref>Goodman, 1994</ref>
