Birds

Definition of Birds as it relates to Animals

Birds are feathered, winged, bipedal, endothermic (warm-blooded), egg-laying, vertebrate animals. They belong to the class Aves, characterized by the presence of beaks without teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds inhabit a wide range of environments across the globe, from dense forests to open grasslands, deserts, and arctic tundra. They exhibit diverse behaviors, including complex vocalizations, social structures, and migratory patterns. Their ability to fly has made them a symbol of freedom and inspiration for humans throughout history. Birds play crucial ecological roles as pollinators, seed dispersers, and pest controllers, contributing significantly to the balance of ecosystems and biodiversity.
