A bird feeder is a device designed to attract and provide food for birds. It typically consists of a container or tray filled with seeds, grains, or other bird-friendly food, along with perches or platforms for the birds to land on while they eat. The bird feeder serves as a convenient food source for birds, especially during times when natural food supplies may be scarce, such as in winter. By using a bird feeder, people can enjoy watching various bird species visit their backyard or garden to feed, creating a delightful and engaging experience for both humans and birds alike.
