CONSERVATION STATUS

Endangered

The Akiapolaau is a small Hawaiian Honeycreeper endemic to the island of Hawaii. It occurs in wet and dry forests between 1,500 and 1,900 meters and is restricted to a few small areas on the eastern side of the island. It forages for insects that live in the bark of native tree species and may be dependent upon the koa tree. The population of the Akiapolaau is thought to number around 1,200 individuals and continues to be threatened by avian diseases, introduced predators and habitat degradation. It has been given a conservation rating of Endangered.

INTERESTING FACTS

  • A group of honeycreepers are collectively known as a "hive" of honeycreepers.
  • It is also called the Hawaiian Woodpecker because it uses its bill to tap tree trunks and branches as it searches for food and sometimes drills holes in ohia trees to drink sap.
  • Males feed on trunks and large branches, whereas females use their slightly smaller bills to forage along the smaller branches.
  • The Akiapolaau faces threats from habitat loss, disease, and introduced species. They are also a slow reproducer, breeding only every other year.
