Most pet birds have an identification band on their leg when they are purchased. These bands are helpful in identifying your bird if they fly away, determining the aviary or birthplace, as well as the year that they were born. Usually, an open band indicates that the bird was born outside the country and a closed band indicates a bird born in the country. There are disadvantages though. If the band doesn’t fit properly, it could cause injuries (broken or sprained legs). Bands should NEVER be removed by the owner! Only a trained veterinarian should remove the band.
