Birds are warm-blooded vertebrates that belong to the class Aves, characterized by feathers, a beak without teeth, and the laying of hard-shelled eggs. They have wings, which are adapted for flight in most species, although some birds are flightless. Birds possess a lightweight skeletal structure, an efficient respiratory system, and a highly developed brain, which aids in their complex behaviors, communication, and problem-solving abilities.
Ecologically, birds play vital roles in various ecosystems as pollinators, seed dispersers, and as part of the food web. They contribute to controlling insect populations and are key indicators of environmental health. Many species have intricate relationships with their habitats, and their presence can reflect changes in ecosystem dynamics, making them important for biodiversity conservation.
