Search for the European Tree Frog

Today we went hiking with just one goal, finding tree frogs.

We never expected to find them on our first attempt
but nevertheless we wanted to give it a try!

Instinctively we chose the right overgrown path and direction

and suddenly we heard a sound (quite similar to a magpie) 

kèkkèkkèkkèkkèk and we realized we were close to some tree frogs.

But we couldn't see them until a amateur wild photographer

helped us and pointed them out.

 Can you find them?

  The kenderman spotted one: tree fogs do climb trees!

And I found this little one all by myself...
