With its three-metre wingspan, the Northern Royal Albatross is the world's largest seabird. Join the Wild South team as they visit Grandma, the oldest known tagged bird of its kind. A gentle, sociable bird, Grandma was one of the first albatrosses to call at Taiaroa Head, near Dunedin, New Zealand - the only mainland breeding colony in the world. Join Grandma six decades on from her first visit, and share in the intimacy of courtship, engagement and the life-long bonding of this rare and beautiful bird. Narrated by Sir David Attenborough.
