A bird leash is a specially designed accessory that allows pet owners to safely take their birds outdoors. It typically consists of a harness that fits around the bird's body and a leash that attaches to the harness, providing control while preventing the bird from flying away. These leashes are available in various sizes to accommodate different species, such as parakeets, cockatiels, and parrots. Using a bird leash can help birds experience the outdoors while ensuring their safety, making it a popular choice among bird enthusiasts.
