There are so many creatures in nature that we don't know about; honestly, I'm very surprised and curious when we learn about them thanks to you. It's very interesting that there's a species of bird that changes color depending on the sunlight. But what impressed me most was the mother bird's struggle to protect her chick and the way she created a protective area. I'm currently researching trees. I know that the acacia tree is a fast-growing tree with long, hard thorns that can protect itself from hot and dry conditions. I never thought that the smallest creatures in nature, ants and insects, would be a food source for birds. This is a wonderful informative article about birds. Congratulations!
