European tree frog also Hyla arborea

Historically, tree frogs were used as barometers because they respond to approaching rain by croaking. Depending on subspecies, temperature, humidity, and the frog's 'mood', skin colour ranges from bright to olive green, grey, brown and yellow. The head is rounded, the lip drops strongly, the pupil has the shape of a horizontal ellipse and the eardrum is clearly recognizable.
