✿ Sound of birds, Sound of trees

It was a lovely day today. When I was taking a walk, I could hear birds were chirping.

I was wondering how many different birds were singing. Looking up and see who are there, but I could only see one black bird. Where are the other birds, I thought.

How about trees, I wonder. Have you heard sound of trees?

I was wondering what kind of sounds trees make.

At home, I tried to listen to my cherry tree in my back garden, I could hear some sound. However I was not sure if it was from the tree or somewhere else. I am making a simple tool that might be able to help me. If it works, I will share it at the upcoming workshop "Organic Picnic & Retreat".

With appreciation
