The Hawaiʻi ʻamakihi (Hemignathus virens), also known as the common ʻamakihi, is a species of Hawaiian honeycreeper.
Distribution and habitat
It is found on the Big Island, Maui, and Molokaʻi in Hawaii. It formerly occurred on Lānaʻi where it was last seen in 1976. It is one of the most common honeycreepers, inhabiting all types of habitat on the islands at elevations from sea level to 8,000 feet (2,400 m). Of all the forest birds native to Hawaii, the Hawaiʻi ʻamakihi 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 ʻapapane, it is one of the two Hawaiian honeycreepers listed by the IUCN as being of least concern.
The Hawaiʻi ʻamakihi is a small bird, measuring about 10 centimetres (3.9 in) in length. It is yellow-green with a small black bill that is 1.3 centimetres (0.51 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.
It has two subspecies: H. v. wilsoni on Maui, Molokaʻi, and (formerly) Lānaʻi, and H. v. virens on the Big Island of Hawaiʻi. The Oʻahu ʻamakihi (H. flavus) and Kauaʻi ʻamakihi (H. kauaiensis) were formerly included in this species.
The Hawaiʻi ʻamakihi 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 ʻōhiʻa lehua (Metrosideros polymorpha), ʻākala (Rubus hawaiensis), and māmane (Sophora chrysophylla). If necessary, it will suck juice from fruits. The Hawaiʻi ʻamakihi also hunts for spiders and insects among trees and shrubs.
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(s) hatches after two weeks and out comes naked except for a couple of yellow feathers. After two to three weeks, the chicks are fledged and then off to find a new territory of their own.
