Invasive Species Threat Summary

The Mangaia kingfisher (Todiramphus ruficollaris) is classified as ‘Vulnerable (VU)’ in the IUCN Red List of Threatened Species. It is confined and endemic to Mangaia island in the Cook Islands. The population appears to be stable with numbers estimated at between 400 and 700 individuals. It inhabits makatea (raised limestone forest) and mature secondary forest and prefers to nest in coconut and barringtonia tree cavities.

The common myna (a href= http://www.issg.org/database/species/ecology.asp?si=108&fr=1&sts=&lang=EN>Acridotheres tristis) competes aggressively with the kingfisher for food and increases the likelihood of nest failure. Cats (Felis catus), Pacfic rats (Rattus exulans) and black rats (Rattus rattus) are potential kingfisher predators. In addition browsing goats (Capra hircus) and pigs (Sus scrofa) increase forest fragmentation and decrease forest regeneration, respectively.

Invasive Species Management Summary

While there have been no conservation actions put in place for the Mangaia kingfisher several studies and invasive species eradication feasibility assessments have been made. In 1996 survey, vegetation and rat-trapping studies were conducted to establish baseline information for conservation. A year later a species census (using the Distance Sampling Method) was conducted. A myna eradication feasibility study in 2006 and concluded that such an eradication would be possible at a cost of NZ$ 100 000. Finally a study to determine Mangaia kingfisher nesting success in an area with a high density of mynas was started in 2006.
