A message from Dr. David Duffy, Pacific Cooperative Studies Unit (PCSU), University of Hawaii (posted 05 November 2012): Because of a lack of funds, HEAR (www.hear.org) may close as soon as December 15, although there may be enough funds to extend it until February 15. This will mean several things. The web site will be placed on a new server although it is not clear who will pay for the server or for transitioning the site. HEAR data will not be updated. The Pacific Ecosystems at Risk (PIER) (http://www.hear.org/pier/abtproj.htm) site will also become frozen, as will numerous books, reports and papers (http://www.hear.org/). As software evolves we will likely lose the ability to access the data. The various list servers will need new owners, otherwise moderated lists will cease to function altogether, while other lists will not be able to add or delete members. The photo collection (http://www.hear.org/starr/images/?o=plants) will remain accessible, but only through a third party site that will charge for access. I should point out that we have already lost the original homes of both the Pacific Basin Information Node (PBIN) and Pacific Ecosystems at Risk (PIER) although they have found temporary refuges. Together with HEAR, they represent the corporate memory both here in Hawaii and across the Pacific of efforts to sustain our natural ecosystems and agriculture against problems caused by species alien to the islands. HEAR also serves as the glue that holds the community together, providing information and facilitating communication. I just hope hindsight is kind to this decision.

Hawaiian Amakihi - Introduction
An introduction to the amakihi complex is provided by The Birds of North America. Access to other articles require subscription.
Hawaii amakihi information from the Pacific Island Network, National Park Service 
Description, status, inventories, and sightings for the Hawaii amakihi are provided on this "Featured Resource" document from the NPS.
Amakihi interesting facts
Amakihi image and interesting facts are on the RightBird site.
Hawaii Amakihi - Images and overview
Amakihi information and images are provided by the Maui Forest Bird Recovery Project.
Hawaii amakihi overview
Hemignathus virens species status, biology, distribution, threats, and conservation actions are described by the Hawaii Department of Land and Natural Resources (Hawaii's Comprehensive Wildlife Conservation Strategy, 2005).
Serological responses and immunity to superinfection with avian malaria in experimentally-infected Hawaii amakihi
Hawaiian honeycreepers that are capable of recovering from acute infections develop concomitant immunity to superinfection, making them functionally immune in areas where malaria transmission has become endemic (Journal of Wildlife Diseases, 2001).
Knemidokoptic mange in Hawaii Amakihi (Hemignathus virens) on the island of Hawaii
Lesions resembling knemidokoptic mange on the feet and tarsometatarsi of two Hawaii Amakihi were observed while the researchers were mist-netting wild passerines at Manuka Natural Area Reserve on the island of Hawaii (J. Wildlife Disease, 2009).
Amakihi image
Image of a captured amakihi is on Forestry Images.
Amakihi distribution
Distribution of Hemignathus virens is from Hawaii's Birds, by Hawaii Audubon Society.
The influence of nectar resources on nesting success and movement patterns of the common amakihi (Hemignathus virens)
Amakihi is intrinsically tied to the nectar resources available within its breeding territory and a minimum of quantity of nectar must be present before territory establishment will occur (The Auk, 1984).

Phenology, reproductive potential, seed dispersal and predation, and seedling establishment of three invasive plant species in a Hawaiian rain forest

Pathogenicity of avian malaria in experimentally-infected Hawaii Amakihi
Mortality results of infected amakihi indicate current elevational and geographic distribution of Hawaiian honeycreepers is determined by relative susceptibility to avian malaria (J. Wildlife Diseases, 2000).
Altitudinal variations in nests of the Hawaiian honeycreeper Hemignathus virens virens
Temperature, altitude, and precipitation affected the placement and thermal conductance of amakihi nests (The Condor, 1984).
Breeding ecology of the hawaii common amakihi
Six major factors influenced amakihi productivity on Mauna Kea. The two most important were length of the breeding season and clutch size (The Condor, 1987).
Serological responses and immunity to superinfection with avian malaria in experimentally-infected Hawaii amakihi
Hawaiian honeycreepers that are capable of recovering from acute infections develop concomitant immunity to superinfection, making them functionally immune in areas where malaria transmission has become endemic (Journal of Wildlife Diseases, 2001).
Artificial incubation, hand-rearing, behavior, and release of common Amakihi (Hemignathus virens virens): Surrogate research for restoration of endangered Hawaiian forest birds
Techniques necessary to hatch, rear, and release endangered Hawaiian honeycreepers are available; however, restoration efforts will probably not succeed unless mosquito-free, predator-controlled reintroduction sites are available or strategies are developed to decrease mortality in naive honeycreepers exposed to disease after release (Zoo Biology, 1998).

| The Hawaiian Ecosystems at Risk project (HEAR) is currently funded by grants from the Hau'oli Mau Loa Foundation and the U.S. Forest Service with support from PCSU (UH Manoa). Historically, HEAR has also received funding and/or support from the Pacific Basin Information Node (PBIN) of the National Biological Information Infrastructure (NBII), PIERC (USGS), the USFWS, HCSU (UH Hilo), and HALE (NPS). |
