コブ白鳥 at 和歌山城･動物園　Mute-swans at Wakayama Castle zoo

何の写真か分かりますか？　2匹のコブ白鳥が頭を水の中に漬けているところです。いつも一匹で優雅に泳いでいましたので、二匹いるとは、初めて知りました。
Do you know what this picture is all about? It is about two mute swans who were immersing their heads into the water. When I come across the swan, it is usually alone swimming elegantly in the water. I noticed that there were two mute swans in the zoo, for the first time.
