lintut

Lintut, also known as lintu in Finnish, refers to birds, a group of warm-blooded vertebrates constituting the class Aves, characterized by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds are found on every continent except Antarctica, and they exhibit a wide range of sizes, shapes, and behaviors. They play crucial roles in various ecosystems, serving as pollinators, seed dispersers, and prey for other animals. Birds are also significant in human culture, often symbolizing freedom, peace, and renewal. There are approximately 10,000 known bird species, with the majority being passerines, or perching birds. Some well-known bird families include the passerines, parrots, and waterfowl. Birds have evolved various adaptations to suit their environments, such as flight, migration, and camouflage. Despite their diversity, all birds share common ancestors and are united by their unique characteristics.
