Specialty: Avian ecology and conservation, demographic modeling, conservation genetics
Research Interests: My research focuses on understanding factors that affect population dynamics – why populations increase or decline over time – and through an understanding of the “why” populations change in size provide natural resource managers information on “how” to maintain healthy populations. My research has focused mainly on birds, mostly endangered species, using field research, modeling, and genetic research to understand population dynamics and identify possible conservation actions to help imperiled populations. My work in Hawai‘i is focused on the native Hawaiian forest birds.
Personal Interests: Hunting, fishing, and lounging at the beach

Automated telemetry reveals post-reintroduction exploratory behavior and movement patterns of an endangered corvid, ʻAlalā (Corvus hawaiiensis) in Hawaiʻi, USA
Continuous movement monitoring is a powerful tool for evaluating reintroduction techniques and assessing how well reintroduced animals are adjusting to the wild. However, to date, continuous monitoring has only occurred for large-bodied species capable of carrying heavy tracking devices. In this study we used an automated VHF radio telemetry array to investigate the exploratory behavior and movemeAuthorsJennifer R Smetzer, Alison L Greggor, Kristina L. Paxton, Bryce M Masuda, Eben H. PaxtonRecent recovery and expansion of Guam’s locally endangered Såli (Micronesian Starling) Aplonis opaca population in the presence of the invasive brown treesnake
Assessing the impacts of invasive predators on the demography and distribution of native species is critical for understanding mechanisms of species persistence and informing the design of recovery programmes. On the oceanic island of Guam, the introduction of the predatory brown treesnake Boiga irregularis after World War II caused the near-total loss of the native forest avifauna.

Paxton, Nicole Suckow, Jeff Quitugua, Haldre RogersDivergent movement patterns of adult and juvenile ‘Akohekohe, an endangered Hawaiian Honeycreeper
The movement patterns of birds across a landscape are often highly variable and influenced by complex interactions between individuals and environments. Because periods of movement can be marked by high mortality, especially among juvenile birds, understanding these patterns may be vital for the conservation of many bird species. However, these patterns can be challenging to quantify. We used radiAuthorsAlex X Wang, Eben H. Paxton, Hanna L Mounce, P. Marcos Gorresen2018 Kaua'i forest bird population estimates and trends
Kaua‘i's native forest birds have experienced steep declines since the beginning of systematic surveys in 1981, and declines have accelerated in recent decades. This report details the analysis of the most recent surveys conducted in 2018. Incorporating the new survey results, long-term trends continue to show sharp declines for all native honeycreeper species with the exception of ‘apapane (HimatAuthorsEben H. Paxton, Kevin W. Brinck, Lisa H. Crampton, Justin Hite, Maria CostantiniStable isotope analysis of multiple tissues from Hawaiian honeycreepers indicates elevational movement
We have limited knowledge of the patterns, causes, and prevalence of elevational migration despite observations of seasonal movements of animals along elevational gradients in montane systems worldwide. While a third of extant Hawaiian landbird species are estimated to be elevational migrants this assumption is based primarily on early naturalist’s observations with limited empirical evidence.

Hawai‘i’s high-elevation forests provide a critical refuge from disease for native forest birds. However, global warming is facilitating the encroachment of mosquitoes and the diseases they transmit into increasingly higher elevations of remaining refugia, threatening the viability of the forest birds across the islands. Multiple management actions to address the threat of disease have been proposAuthorsEben H. Paxton, Jim KrausResearch in the refuge constraints to restoring diverse forest ecosystems at Hakalau

Birds free from nest predators for long periods may either lose the ability to recognize and respond to predators or retain antipredator responses if they are not too costly. How these alternate scenarios play out has rarely been investigated in an avian community whose members have different evolutionary histories. We presented models of two nest predators (rat and snake) and a negative control (AuthorsGeorge C Cummins, Tad C Theimer, Eben H. PaxtonFrequent use of upland habitats by the endangered Hawaiian stilt (Himantopus mexicanus knudseni)
The Hawaiian Stilt, or Ae’o (Himantopus mexicanus knudseni), is an endangered waterbird endemic to the Hawaiian Islands. Loss of suitable wetland habitats due to anthropogenic development is a leading cause for decline, as well as the introduction of non-native predators and invasive wetland plants. This study fitted four Hawaiian Stilts with GPS satellite tags to document their use of wetland anAuthorsMartha Kawasaki, Patrick J. Hart, Eben H. PaxtonEvaluating community-level response to management actions across a diverse Hawaiian forest bird community
Although species‐specific approaches are necessary to understand the dynamics of individual species composing a community, they do not offer a framework for making optimal management decisions at the community level. Here, we present a simple framework for comparing the response of entire communities to multiple management scenarios. Our approach uses a weighted average of standardized species‐speAuthorsAlban Guillaumet, Eben H. PaxtonSeasonality and prevalence of pollen collected from Hawaiian nectarivorous birds
Hawaiian nectarivorous forest birds play a vital ecological role as pollinators in Hawaiian ecosystems. However, little is known about what nectar resources are utilized by Hawai‘i’s nectarivorous birds, how seasonality influences nectar availability, and how nectar preference differs by bird species. We sampled pollen from the heads of ‘i‘iwi (Drepanis coccinea), ‘apapane (Himatione sanguinea), HAuthorsKathryn van Dyk, Kristina L. Paxton, Patrick J. Hart, Eben H. PaxtonPatch age since disturbance drives patch dynamics for flycatchers breeding in both reservoir and riverine habitat
Species dependent upon early-successional landscapes often occupy patches at different stages of recovery after disturbance. The demographic processes that drive patch dynamics in these systems have rarely been described but are important for developing effective conservation and management plans, especially when humans have modified the timing and intensity of disturbances that drive regenerationAuthorsTad C Theimer, Mark K.
