The Hawai{{okina}}i {{okina}}amakihi (Chlorodrepanis virens), also known as the common {{okina}}amakihi, is a species of Hawaiian honeycreeper.

Taxonomy

The Hawai{{okina}}i {{okina}}amakihi was formerly placed in the genus Hemignathus but was assigned to the genus Chlorodrepanis based on the phylogenetic analysis of mitochondrial and nuclear DNA sequences.[2][3]

There are two recognised subspecies: C. v. wilsoni on Maui, Moloka{{okina}}i, and (formerly) Lāna{{okina}}i, and C. v. virens on the Big Island of Hawai{{okina}}i.[3]

Distribution and habitat

It is found on the Big Island, Maui, and Moloka{{okina}}i in Hawaii.[4] It formerly occurred on Lāna{{okina}}i where it was last seen in 1976.[4] It is one of the most common honeycreepers, inhabiting all types of habitat on the islands at elevations from sea level to {{convert|8000|ft|m}}. Of all the forest birds native to Hawaii, the Hawai{{okina}}i {{okina}}amakihi has been affected the least by habitat changes. It is suspected that it is evolving resistance to diseases such as avian malaria. Along with the {{okina}}apapane, it is one of the two Hawaiian honeycreepers listed by the IUCN as being of least concern.

Description

The Hawai{{okina}}i {{okina}}amakihi is a small bird, measuring about {{convert|10|cm|in}} in length.[5] It is yellow-green with a small black bill that is {{convert|1.3|cm|in}} long and has brown eyes with black pupils. It is a small bird with a powerful voice. It utters short chirps, aki, ki, ki, a, which can be heard well over a mile away.

Behaviour

Feeding

The Hawai{{okina}}i {{okina}}amakihi has a very wide diet, and has been able to find food despite habitat alteration. It has a tubular tongue, which it uses to drink nectar from flowers such as those of the {{okina}}ōhi{{okina}}a lehua (Metrosideros polymorpha), {{okina}}ākala (Rubus hawaiensis), and māmane (Sophora chrysophylla). If necessary, it will suck juice from fruits. The Hawai{{okina}}i {{okina}}amakihi also hunts for spiders and insects among trees and shrubs.[5]

Breeding

During the breeding season, between January and March, it makes a small nest made of woven plant fibers, and in most cases lays only a single egg. Only in rare cases does this bird lay two eggs. The chick hatches after two weeks, naked except for a few yellow feathers. After two to three weeks, the chick is fledged and departs to find a new territory of its own.
