エミュー at 和歌山城･動物園　An emu at Wakayama Castle zoo

和歌山城･動物園の怪獣？イイエ、これはエミュの顔の拡大写真です。口を開けているのは、鳥には汗腺が無いので、暑い時は口を開けて熱を発散させます。

Is it a monster at Wakayama Castle zoo? No, it is an enlarged picture of the face of an emu. On birds, there is no sweat gland, therefore, in order to disperse heat he opens his mouse to let the heat get out of his body.
