Acridotheres tristis

Myna birds are now found at high population around Samoa. They were at sight everywhere but seem more frequent around people's compounds and personal properties as well. Upon completion of the 9th poison baiting operation, the team conducted its 10th phase of baiting operation in Savaii for two weeks. This work marked as the second control work to be done in the big island.

Indian myna birds were introduced in Samoa within different periods for such reasons as to control cattle ticks. They have now spread to most parts of two main habitat islands of Samoa, Upolu and Savaii. The two introduced species of myna have now been commonly known as the Common Myna and the Jungle Myna.

Experience shows that you can get rid of myna while their population is small, but once the population becomes widespread, ongoing management will be required if the impacts of myna are to be reduced. This guide offers solutions and advice on how to decide what to do if myna are an issue in your country and was prepared by David Butler and Bill Nagle, who have assisted Pacific countries with myna solutions for both goals of eradication and control.

This document builds on lessons learned from 10 years of DEC-MNRE action on the myna issue, training workshops on invasive species management, a 2015 myna population transect survey (conservative estimate of total population in Samoa between 129,407 and 188,583 birds), appropriate literature and experiences in Pacific and other countries. Recommendations are made on strategies and the priority information needed to implement those strategies.

In Seychelles, the common myna has been shown to have a negative impact on endangered endemic birds on Denis Island, interfering with breeding attempts and attacking adult endemic birds at their nests. This stimulated an attempt to eradicate the island's mynas.

Invasive plants and animals inflict much damage on native species and this is particularly the case on isolated oceanic islands with high degrees of endemism. Such islands commonly are important refugia for species of high conservation value. Some of the most pervasive and potent of invasive animal species are birds of the myna (Acridotheres) and bulbul (Pycnonotus) genera that historically were introduced to isolated islands as biological control agents for the management of insect pest species that can cause considerable economic damage to agricultural crops and wider ecosystems.

This report is based on official trip made to Onotoa early this year 2014. IAS project under ECD together with ALD from MELAD was made to fulfill the obligation of ECD as an implementing agency. In 2012, there is a survey trip made to confirm the distribution and number of myna birds on Onotoa in order to set up appropriate actions to cease the disturbances and destruction caused by this bird.

The Division of Environment and Conservation of the Ministry of Natural Resources and Environment of the Government of Samoa (DEC-MNRE) is implementing a project as part of the Global Environment Facility - Pacific Alliance for Sustainability (GEF-PAS) Invasive Alien Species project funded by the United Nations Environment Program and executed by SPREP. The project identifies the need to determine realistic management goals and best management practices for myna species in Samoa and use them to write a management plan.
