About These Birds
Black Swan
The black swan was once considered impossible by Europeans who believed all swans were white, making it a famous philosophical example of inductive reasoning failure. It is the state emblem of Western Australia. Black swans form lifelong pair bonds and both parents share in incubation and care of cygnets.
Hawfinch
锡嘴雀是欧洲和亚洲温带林地的粗壮雀类，喙硕大有力，可以磕开坚硬的果核。羽色棕褐，头部具橙棕色，翅黑色带白斑。栖息于落叶林和混交林，以硬果、浆果和种子为食。冬季常集结成群在林地觅食。
