He would hoot and then wait for the echo to return.

One day, a rustle in the leaves made Oliver stop hooting.

He saw a small gnat dancing in the moonlight.

Oliver decided to join the gnat and started to whistle.

The gnat stopped to listen and began to dance to Oliver's whistle.

The echo of Oliver's whistle filled the forest, and the gnat danced faster.

Oliver and the gnat continued to dance and whistle till morning.

As the sun rose, Oliver decided to fasten his eyes on the gnat and said goodbye.

Oliver sat on his branch, listening to the morning choir of birds.

He felt a sense of joy and hastened to join the choir with his own hoot.

With a final hoot and a flap of his wings, Oliver flew off, ready for a new day.
