Who are the prey and predators of the Japanese white eyes?

The Japanese White-eye , also known as the mejiro, is a small bird in the family. The white-eye specific epithet is occasionally written japonica, but this is incorrect due to the gender of the genus. Its native range includes much of East Asia, including Japan, China, Vietnam, and the Philippines. It has been intentionally introduced to other parts of the world as a pet and as pest control, with mixed results. As one of the native species of the Japanese islands, it has been depicted in Japanese art on numerous occasions, and historically was kept as a cage bird.

The Japanese White-eye is about 4 to 4.5 inches in size, with a green forehead and a yellow throat, a greenish back, and dark brown wings and tail outlined in green. Like other white-eyes, this species exhibits the distinctive white eyering that gives it its name (mejiro also meaning "white eye" in Japanese). It is omnivorous, feeding primarily on insects and nectar. When building nests, they often steal material from the nests of other birds.

Introduced to Hawaii in 1929 as a means of insect control, it has since become a common bird on the Hawaiian Islands, and has become a vector for avian parasites that are now known to adversely affect populations of native birds such as Hawaiin honeycreepers, as well as spreading invasive plant species through discarded seeds.
