Climate change and disease are linked to the rapid decline of native birds on Hawaiian island Kaua‘i.
Abstract: The majority of bird extinctions since 1800 have occurred on islands, and non‐native predators been the greatest threat to persistence island birds. Island endemic species often lack life‐history traits behaviors that reduce probability predation they can become evolutionarily trapped if are unable adapt, but few studies examined ability respond novel predators. Oahu Elepaio ( Chasiempis ibidis ), an endangered Hawaiian forest bird, is nest by black rats Rattus rattus ). I whether...
Offshore wind energy development (OWED) is rapidly expanding globally and has the potential to contribute significantly renewable portfolios. However, of infrastructure in marine environment presents risks wildlife. Marine birds particular have life history traits that amplify population impacts from displacement collision with offshore infrastructure. Here, we present a broadly applicable framework assess mitigate OWED on birds. We outline existing techniques quantify impact via monitoring...
Unrelated same-sex individuals pairing together and cooperating to raise offspring over many years is a rare occurrence in the animal kingdom. Cooperative breeding, which animals help that are not their own, often attributed kin selection when related, or altruism unrelated. Here we document long-term of unrelated female Laysan albatross ( Phoebastria immutabilis ) show how cooperation may have arisen as result skewed sex ratio this species. Thirty-one per cent pairs on Oahu were...
One-third of the bird species listed under US Endangered Species Act are endemic to Hawaii. One requirement delisting a is elimination or abatement threats that species. More than 95% Hawaii's threatened and endangered face multiple cannot be eliminated (e.g., alien mammalian predators, invasive plants alter habitat structure, disease). However, because we can manage many at scales which achievement recovery goals possible, these could delisted if conservation partners committed...
Egg turning is unique to birds and critical for embryonic development in most avian species. Technology that can measure changes egg orientation temperature at fine temporal scales (1 Hz) was neither readily available nor small enough fit into artificial eggs until recently. Here we show the utility of novel miniature data loggers equipped with 3-axis (i.e., triaxial) accelerometers, magnetometers, a thermistor study behavior free-ranging birds. Artificial containing were deployed nests...
ABSTRACT The Oahu elepaio ( Chasiempis sandwichensis ibidis ) is an endangered forest bird endemic to the Hawaiian island of (USA) and threatened by nest predation from alien rodents mosquito‐borne diseases. I investigated importance these threats evaluated success conservation efforts 1995 2008. controlled with snap‐traps bait stations in 3 valleys switched sites non‐treatment treatment over time. mist‐netted color‐banded 91 elepaio, inspected them for symptoms avian poxvirus Poxvirus avium...
This is the second report of Hawaii Bird Records Committee (HBRC). From 2019 to 2024, HBRC reviewed 37 reports involving 29 bird species, which 34 26 species were accepted, two rejected, and one required recirculation still under review. The accepted included 15 new Hawaiian Islands, eight records, third record, sixth record. Two more added because splits taxa that had been recorded previously. Through Islands checklist includes 355 species.
The O'ahu 'Elepaio Chasiempis sandwichensis ibidis is an endangered monarch flycatcher endemic to the Hawaiian island of O'ahu. Nest predation by alien Black Rats Rattus rattus one main causes decline this forest bird. From 1996 2000 we monitored demography largest remaining population and controlled rats with snap traps poison bait stations in attempt begin recovery species. influenced many aspects demography. Rat control resulted a 112% increase reproduction, 66% survival female 'Elepaio,...
Avian pox virus (Poxvirus avium) is a mosquito-borne disease that occurs worldwide in variety of bird species, but little known about its prevalence or effect on seabirds. We monitored and fledging success Laysan Albatross (Phoebastria immutabilis) Oahu, Hawaii, from 2003 to 2007. Pox albatross chicks averaged 88% years with high rainfall 3% low rainfall. Diagnosis was clinically confirmed two birds by Muscovy Duck (Cairina moschata) fibrolast cultures. Severity infection ranged small...
Laysan Albatross (Phoebastria immutabilis) began re-colonizing sites across the Pacific in 1970s after severe population declines, and fledged first chick on island of Oahu 1992. We report status populations at Kaena Point Kuaokala Oahu, Hawaii provide new demographic data for this species. Colonies were monitored weekly from 2004 to 2008; all individuals censused, banded, genetically identified gender. There was a 365 adults 2008 which 47% active breeders. The breeding increased 27%...
Abstract Animals often exhibit predictable geographic variation in morphology, and such ecogeographic patterns reflect local adaptation to varying environmental conditions. The most common of these are termed Bergmann's, Allen's, Gloger's rules. I studied morphological the Hawaii Elepaio (Chasiempis sandwichensis) Oahu (C. ibidis), forest birds endemic Hawaiian Islands. measured body size plumage color 223 live elepaios captured at 36 sites on 132 23 Oahu, examined museum specimens from an...
The Northwestern Hawaiian Islands support some of the largest tropical seabird colonies in world, but these low-lying islands are threatened by sea level rise and increasing storm surge associated with climate change. Protection suitable nesting habitat creation new breeding on higher main among highest priority conservation actions for seabirds. From 2015 to 2018, we used social attraction translocation begin establishing two vulnerable seabirds, Laysan albatross black-footed albatross,...
On O'ahu, Wedge-tailed Shearwaters (Puffinus pacificus) and other seabirds nest primarily on small offshore islets, but fossil evidence shows that many seabirds formerly bred O'ahu itself. Predation by introduced mammals is suspected to be the primary factor preventing shearwaters other seabirds from reestablishing large nesting colonies O'ahu. We investigated effects of predation comparing three unmanaged colonies at Malaekahana State Recreation Area where feral cats are fed public, with a...
Rats were eradicated from Mokoli'i, a 1.6-ha island off the east shore of O'ahu, using snap traps, cage and diphacinone bait stations. A total 18 black rats (Rattus rattus) caught, 354 blocks used. There was no sign on after 27 May 2002. Wedge-tailed Shearwaters (Puffinus pacificus) nest but only single chick survived during 1999–2001; number surviving chicks increased to 126 in 2002 185 2003. The intertidal invertebrates native plants, including endangered Carter's panic grass (Panicum...
Estimating and monitoring adult juvenile survival are vital to understanding population status, informing recovery planning for endangered species, quantifying the success of management. We used mark–recapture models estimate apparent annual Puaiohi (Myadestes palmeri), an thrush endemic Hawaiian island Kauai, from 2005 2011. Our sample included 87 wild birds 123 captive-bred that were released at various ages. Survival was higher males (0.71 ± 0.09) than females (0.46 0.12). juveniles (0.23...
Understanding population dynamics and determining conservation priorities in long-lived species with delayed breeding often is hampered by lack of information about younger age classes. Obtaining accurate estimates juvenile survival recruitment can be difficult because young individuals are infrequently observed. We used mark–recapture models to estimate age-specific survival, recruitment, size, encounter probability Laysan Albatrosses (Phoebastria immutabilis) using a 14-yr dataset from...
The O'ahu ‘Elepaio (Chasiempis sandwichensis ibidis) is an endangered monarch flycatcher endemic to the Hawaiian Island of O'ahu. One main causes decline this forest bird low nest success. This study investigated whether introduced rodents might be important predators in habitat by conducting artificial experiments before and during a rodent control program. In each experiment, 20 nests with two quail eggs were placed on ground trees, then checked at 5, 10, 15 day intervals. size,...
I studied intraspecific variation in foraging behavior of an endemic, insectivorous bird, the Elepaio (Chasiempis sandwichensis), two Hawaiian forests that differed degree human modification. The undisturbed forest had a closed canopy, dense understory, and groundcover native plants. disturbed much lower tree shrub densities, ground cover alien grasses. Search-and-attack rates, proportions attack maneuvers, proportional substrate use between habitats. Birds habitat attacked prey two-thirds...
