The Whenua Hou Diving Petrel (WHDP) has been classified as ‘Nationally Critical’ with the entire population existing as a single colony of ~200 individuals on the sand dunes of Whenua Hou/Codfish Island. My research investigated various aspects of the foraging ecology of WHDPs to help us on our way to understanding why they are so rare. Come along to hear what we have learned about these little ones so far!
