Query: Best Children's Book ever

My mom bought this book in 1956 for my sister and me. It remained a favorite from our childhood. I was a teacher and then a curriculum trainer and have since retired. However, I have never seen a book as excellent in content, vocabulary, and artwork as this story holds. Chee-Chee is a good little bird who helps Keeko, the little native scout. help the animals of the forest. Meany cat and his mother scare them and are mean to the other animals of the forest, but when Meany Cat falls into the river, Keeko coordinates his rescue with Father Moose. Fifty-five years later, I can remember the beautiful eyes of Mama Cat as tears well up in her eyes at the other creatures' thoughtfulness, winning her and Meany Cat over to different ways. A powerful and precious story. The review above answers my question as to the artist.What a talented illustrator/author.
