Samoan authorities have renewed efforts to control two species of Myna birds which are threatening native wildlife and crops.
The new campaign, which is supported by the local Animal Protection Society, involves the introduction of an Australian-designed trap at a plantation on Upolu Island.

Mynas have taken over the pulu trees of Apia annoying business owners and pedestrians with deafening noise at sunset.
The working group says they are aggressive and territorial birds which bully native species.

The jungle myna was introduced in 1965, the common variety in 1988, both to control pests.
