Мини сочинение о происшествии из жизни в past simple

Yesterday I went to a supermarket to buy something to eat. Walking in a small city garden I noticed a nest fallen from the tree. I came closer and saw a little bird sitting beside the nest. It was silent and had its eyes wide open. I looked around but saw no other birds. I decided to go to the supermarket another day. I took the small thing and went back home. At home I searched information about the bird on the internet and thus I learned how to look after it and what it ate. Now I hope it will get better and bigger soon and I will let it free.
