Breeding productivity and survival of the endangered Hawai'i Creeper in a wet forest refuge on Mauna Kea, Hawai'i

We studied the demography of the endangered Hawai‘i Creeper (Oreomystis muna) from 1994-1999 at three sites in Hakalau Forest National Wildlife Refuge (NWR). Hawai‘i Creepers bred from January to June, with peak breeding in February through May (about 120-l 80 days), and molted from May to August. A small proportion (4.9%) of individuals...

Age and sex determination of the Maui Parrotbill

We determined the best plumage and morphometric variables for ageing and sexing the Maui Parrotbill (Pseudonestor xanthophrys), an endangered Hawaiian honeycreeper found only on east Maui, Hawaii, by examining and measuring 30 museum specimens and 71 live birds captured in mist nets. Juvenal plumage was identified by the presence of pale-tipped...

What caused the population decline of the Bridled White-eye on Rota, Mariana Islands?

The Bridled White-eye (Zosterops conspicillatus rotensis) was Once thought to be common and widespread on Rota, Commonwealth of the Northern Mariana Islands, but is now restricted to several patches of native limestone forest in and adjacent to the Sabana region. Surveys conducted in 1990 indicated that the population had declined by 87% between...

Conservation status and recovery strategies for endemic Hawaiian birds

Populations of endemic Hawaiian birds declined catastrophically following the colonization of the islands by Polynesians and later cultures. Extinction is still occurring, and recovery programs are urgently needed to prevent the disappearance of many other species. Programs to recover the endemic avifauna incorporate a variety of conceptual and...

Drepanidine movements in relation to food availability in subalpine woodland on Mauna Kea, Hawai'i

Flowers of the mamane tree (Sophoru chrysophylla) are the primary nectar source for Hawaiian honeycreepers in subalpine woodland on Mauna Kea Volcano on the island of Hawai‘i. Mamane seeds are the primary food resource of the endangered Palila (Loxioides bailleui), which is now restricted to subalpine woodland on Mauna Kea. The objectives of this...

Reintroduction and translocation of 'Oma'o: A comparison of methods

We reintroduced 25 captive-reared ‘Oma‘o (Myadestes obscurus) and translocated 16 wild-caught ‘Oma‘o to former range in the Pu‘u Wa‘awa‘a Wildlife Sanctuary on the island of Hawai‘i to develop and refine methods that might be used in the recovery of the closely related and critically endangered Puaiohi (Myadestes palmeri) on Kaua‘i. Captive-reared...

Seedling mortality in Hawaiian rain forest: The role of small-scale physical disturbance

Most montane rain forests on the island of Hawaii consist of a closed canopy formed by Cibotium spp. tree ferns beneath an open canopy of emergent Metrosideros polymorpha trees. We used artificial seedlings to assess the extent to which physical disturbance caused by the senescing fronds of tree ferns and the activities of feral pigs might limit...

Serological responses and immunity to superinfection with avian malaria in experimentally-infected Hawaii Amakihi

Six of seven Hawaii Amakihi (Hemignathus virens) with chronic malarial infections had no increases in peripheral parasitemia, declines in food consumption, or loss of body weight when rechallenged with the homologous isolate of Plasmodium relictum 61 to 62 days after initial infection. Five uninfected control amakihi exposed at the same time to...

The Hawai'i rare bird search 1994-1996

We compiled the recent history of sightings and searched for 13 rare and missing Hawaiian forest birds to update status and distribution information. We made 23 expeditions between August 1994 and April 1996 on the islands of Hawai‘i, Maui, Moloka‘i, and Kaua‘i totaling 1,685 search hours, 146 field days, and 553 person days. During our surveys we...

Plant phenology in a cloud forest on the island of Maui, Hawaii

We recorded the times of flowering, fruiting, and leafing of ten native canopy and subcanopy trees and shrubs (monthly from December 1994 through December 1997) in a montane cloud forest with relatively aseasonal rainfall on the island of Maui, Hawaii. These species represented the great majority of individual woody plants at the site. Flowers...

Characterization of poxviruses from forest birds in Hawaii

Two strains of avian pox viruses were isolated from cutaneous lesions in Hawaiian crows (Corvus hawaiiensis) examined in 1994 and a third from a biopsy obtained in 1992 from an infected bird of the Apapane species (Himatione sanguinea) by inoculation of the chorioallantoic membranes (CAM) of developing chicken embryos. The resulting proliferative...
