Research on Tiger Sharks in Norfolk Island and New Caledonia

• Norfolk Island: A remote island that attracts large tiger sharks due to a unique food source: wedge-tailed shearwaters.
• Diet Analysis: Isotope analysis revealed that seabirds make up the majority of the tiger sharks' diet, not cow carcasses as initially hypothesized.
• Hunting Strategy: Tiger sharks target rafts of shearwaters at dusk, using their large mouths to scoop them up.
• New Caledonia: Tiger sharks migrate to New Caledonia in the winter, possibly to pup in the warmer waters.
