ʻAkohekohe
The akohekohe (''Palmeria dolei'') or crested honeycreeper is a species of Hawaiian honeycreeper. It is endemic to the island of Maui in Hawaii. Its natural habitat is wet forests dominated by ''koa'' (''Acacia koa'') and ''ōhia lehua'' (''Metrosideros polymorpha'') on the windward side of Haleakalā at elevations of . It is the largest honeycreeper on the island at in length. The adults are a glossy black with whitish feathers and stripes going down its side. The underparts are whitish black while the top has orange feathers sticking from wings. The feathers behind the eyes are a reddish color, and have a stream of cream colored feathers coming from the eyes. One of the things that most people recognize about this bird is its whitish gold colored feather crest on its head. The younger birds are brownish black and they do not have the orangish feathers of the parents. The legs and bills are a blackish color. It has a variety of songs. The most well known of the calls is a pair of ''whee-o, whee-o'', being repeated over and over again. Also another well known song is a descending thrill which is done about five seconds apart. It songs include a low chuckling sound, ''tjook, tjook, chouroup'' or a rarer song, ''hur-hur-hur-gluk-gluk-gluk''. During a search for the species in the east Maui forests, there were a record of 415 observations over an area of and at elevations from above sea level. It has been estimated that there are a total of 3,800 akohekohe left on Maui in two populations separated by the Koolau Gap.
== Diet ==
The akohekohe is a nectarivore that feeds on the flowers of ''ōhia lehua'' (''Metrosideros polymorpha'') high up in the canopy. It is an aggressive bird and will drive away competing nectarivores, such as the related ''apapane'' and iiwi. When ''ōhia lehua'' blossoms are limited, it will eat insects, fruit, and nectar from other plants. The akohekohe will forage in the understory if necessary, where food plants include ākala (''Rubus hawaiensis'').〔
