Common birds are species that are frequently found in various environments, including urban areas, parks, and forests. Examples include the American Robin, known for its bright orange belly, and the House Sparrow, which often gathers in flocks around human habitats. These birds are adaptable and can thrive in diverse conditions. Many common birds play essential roles in ecosystems, such as controlling insect populations and pollinating plants. The Northern Cardinal, with its striking red plumage, is another familiar sight in gardens. Observing these birds can enhance our appreciation for nature and promote conservation efforts.
