Wild birds are birds that live in their natural habitats without human intervention. They can be found in various environments, including forests, wetlands, grasslands, and urban areas. Wild birds play essential roles in ecosystems, such as pollination, seed dispersal, and controlling insect populations. There are thousands of species of wild birds, each with unique characteristics and behaviors. Some common examples include sparrows, eagles, and hummingbirds. Wild birds are often studied by ornithologists, who observe their habits and interactions within their ecosystems to better understand their roles in nature.
