Taipei Tree Frog

Last week I finally saw my first frog in Fu Yang Park, which is an important habitat of Taipei Tree Frog. My son saw his first frog couple months ago on his second visit, but I never saw any before when I visited the park. On the contrary, I saw snakes more often. This time I finally met one, when I did not have my camera with me. The photo was taken with my cell phone, so it was hard to control what I captured. Can you find the frog?
