Timing of breeding and molting in six species of Hawaiian honeycreepers

The timing of breeding and molting was studied in six species of Hawaiian honeycreepers with differing food habits on the Island of Hawaii. The availability of nectar was highly seasonal, whereas insect abundance was relatively constant throughout the year. All six species of honeycreeper had extended breeding and molting periods with peak...

Identifying sex and age of apapane and iiwi on Hawaii

Methods to determine the sex and age of Apapane (Himatione sanguinea) and Iiwi (Vestiaria coccinea) were developed on the basis of 189 museum specimens and 91 live birds captured in mist nets on the Island of Hawaii (USA). Both species retain all juvenal primaries and some juvenal secondaries and body feathers after the first prebasic molt and...

Sex and age identification of palila

Methods to sex and age Palila (Loxioides bailleui), an endangered Hawaiian finch restricted to subalpine woodlands on Hawai'i, were identified on the basis of measurements and plumage characteristics of 17 museum specimens and 96 known-age, live Palila. Palila undergo a single annual molt during September-December following the breeding season....

Site tenacity of the endangered palila

Strong site tenacity might prevent Palila (Loxioides bailleui), an endangered Hawaiian honeycreeper, from repopulating favorable habitats in their former range. We used radio telemetry during the nonbreeding and breeding seasons to study movements and dispersal rates of 57 Palila. All Palila remained in the study area, and home range sizes and...

Eggs, nests, and nesting behavior of akiapolaau (Drepanidinae)

We describe the fifth verified nest and first verified egg of the Akiapolaau (Hemignathus munroi), an endangered Hawaiian honeycreeper. We dispute the validity of Bryan?s (1905a) description of three eggs and two nests of the Akiapolaau. Eggs that he attributed to this species were much smaller than ours, and his nest descriptions did not match...

Snaring to control feral pigs sus scrofa in a remote Hawaiian rain forest

Feral pig Sus scrofa control in Kipahulu Valley, a remote rain forest in Haleakala National Park, Maui, Hawaiian Islands, has been achieved with snares over a 45-month period. Initial pig densities in fenced management units of 6·2 km2 and 7·8 km2were estimated at 6 animals/km2 and 14·3 animals/km2 for the two units, based on population...

Status and population trends of Hawaii's native waterbirds, 1977-1987

Status and population trends of Hawaiis ’ native waterbirds were examined from 1977 through 1987. Waterbird population fluctuations were analyzed in relation to rainfall and land use dynamics. Numbers of Hawaiian Duck (Koloa) (Anus wyvilliana) and Hawaiian Common Moorhen (Gallinula chloropus sandvicensis) appeared stable over time; however,...

Epidemic pox and malaria in native forest birds

Studies by Warner in the 1950’s and van Riper in the 1970’s identified disease as a potential limiting factor in the distribution and abundance of Hawaii’s native forest birds. Mosquito-transmitted protozoan and viral infections caused by malarial parasites and pox virus were especially significant. Both organisms were introduced to the islands...

Trophic interactions and direct physical effects control phytoplankton biomass and production in an estuary

San Francisco Bay has recently been invaded by the suspension-feeding clam Potamocorbula amurensis. Previous work has shown that phytoplankton biomass in the upper estuary is low (2-3 mg Chl a m-3) during seasonal periods of high river flow and short residence time and it is usually high (peak >30 mg Chl a m-3) during the summer-autumn seasons...
