Peacocks are large, colorful birds known for their striking tail feathers, or "trains," which they fan out during courtship displays. They belong to the family Phasianidae and are native to South Asia, although they have been introduced to other regions. The most common species is the Indian Peafowl, recognized for its vibrant blue and green plumage. These birds are omnivorous, feeding on a diet that includes seeds, insects, and small reptiles. Peacocks are also known for their loud calls, which can be heard over long distances. They typically live in forests and grasslands, often seen foraging on the ground.
