Hindella) Fiordland penguins and b) Snares penguins tracked over the non-breeding migrations from February 2018 to July 2018 and April 2013 to September 2013 respectively. Within a species, most birds dispersed in the same direction, except for one female Fiordland penguin from Codfish Island/Whenua Hou, which spent the entire winter period on the Campbell Plateau, and one Snares penguin which returned via the Bass Strait.
