Passage: 28
Birds are warm-blooded animals that have feathers, wings, and beaks. Most birds can fly, but some, like ostriches and penguins, cannot. Birds lay eggs and usually build nests to protect their young ones. They play an important role in nature by helping with pollination and spreading seeds. Birds also help control insects and pests, which benefits farmers. Unfortunately, many bird species are endangered due to habitat loss, hunting, and pollution. Protecting birds and their habitats is essential for maintaining ecological balance.
