Dr Jim Mills returns to New Zealand from the Unted States each year to don overalls, hat and earmuffs and get among the red-billed gulls of Kaikoura. The biggest threat to the colonies today is predation by feral cats which now threaten the long-term viability of red-billed gull and white-fronted tern colonies at Kaikoura. Dr Mills links the increased predation to the introduction of the rabbit calicivirus disease — cats have 'prey switched. One or two cats can, over the course of a breeding season, destroy 1000-3000 nests and kill large numbers of chicks and adults.
