Birds in the sky

I see birds in the sky, and that is not a lie.
It’s late in the afternoon, and they whistle a tune.
They are sitting in a tree, but one bird flies to me.
I give him some bread, and he looks very glad.
Suddenly I see a cat, and the bird flies over my head.
The cat is ready for an attack, but he is too slow and lands on his back.
I give the cat an embrace, and I see a big smile at the birds face.
