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

Tamarix as wildlife habitat
Home range and use of habitat of western yellow-billed cuckoos on the middle Rio Grande, New Mexico
The western yellow-billed cuckoo (Coccyzus americanus occidentalis) is a Distinct Population Segment that has been proposed for listing under the Endangered Species Act, yet very little is known about its spatial use on the breeding grounds. We implemented a study, using radio telemetry, of home range and use of habitat for breeding cuckoos along the Middle Rio Grande in central New Mexico in 2007
Tamarisk in riparian woodlands: A bird’s eye view
One year of migration data for a western yellow-billed cuckoo
Elucidating spatially explicit behavioral landscapes in the Willow Flycatcher
Animal resource selection is a complex, hierarchical decision-making process, yet resource selection studies often focus on the presence and absence of an animal rather than the animal's behavior at resource use locations. In this study, we investigate foraging and vocalization resource selection in a population of Willow Flycatchers, Empidonax traillii adastus, using Bayesian spatial generalized

Tamarisk biocontrol using tamarisk beetles: Potential consequences for riparian birds in the southwestern United States
The tamarisk beetle (Diorhabda spp.), a non-native biocontrol agent, has been introduced to eradicate tamarisk (Tamarix spp.), a genus of non-native tree that has become a dominant component of riparian woodlands in the southwestern United States. Tamarisk beetles have the potential to spread widely and defoliate large expanses of tamarisk habitat, but the effects of such a widespread loss of ripa

El Niño-Southern Oscillation is linked to decreased energetic condition in long-distance migrants
Predicting how migratory animals respond to changing climatic conditions requires knowledge of how climatic events affect each phase of the annual cycle and how those effects carry-over to subsequent phases. We utilized a 17-year migration dataset to examine how El Niño-Southern Oscillation climatic events in geographically different regions of the Western hemisphere carry-over to impact the stopoAuthorsKristina L. Paxton, Emily B. Cohen, Eben H. Paxton, Zoltan Németh, Frank R. MooreMonitoring Hawaiian waterbirds: evaluation of sampling methods to produce reliable estimates
We conducted field trials to assess several different methods of estimating the abundance of four endangered Hawaiian waterbirds: the Hawaiian duck (Anas wyvilliana), Hawaiian coot (Fulica alai), Hawaiian common moorhen (Gallinula chloropus sandvicensis) and Hawaiian stilt (Himantopus mexicanus knudseni). At two sites on Oʽahu, James Campbell National Wildlife Refuge and Hamakua Marsh, we conducteAuthorsRichard J. Camp, Kevin W. Brinck, Eben H. Paxton, Christina LeopoldA landscape-based assessment of climate change vulnerability for all native Hawaiian plants
In Hawaiʽi and elsewhere, research efforts have focused on two main approaches to determine the potential impacts of climate change on individual species: estimating species vulnerabilities and projecting responses of species to expected changes. We integrated these approaches by defining vulnerability as the inability of species to exhibit any of the responses necessary for persistence under climAuthorsLucas B.

We evaluated three assays for non-specific or innate immune capacity to see if measurements were independent of malarial infection and capable of distinguishing malaria-tolerant, low-elevation Hawaiʽi ʽAmakihi from malaria-susceptible, high-elevation ʽAmakihi. ʽAmakihi were captured at Malama Ki Forest Reserve (20 m), Hakalau Forest National Wildlife Refuge (1800 m), and Upper Waiakea Forest ReserAuthorsCarter T.

Naturalists in the 1800s described the ʻIʻiwi (Vestiaria coccinea) as one of the most abundant forest birds, detected in forested areas from sea level to tree line across all the major Hawaiian Islands. However, in the late 1800s, ʻIʻiwi began to disappear from low elevation forests, and by the mid-1900s, the species was largely absent from low- and mid-elevation areas. Today, ʻIʻiwi are restricteAuthorsEben H. Paxton, P. Marcos Gorresen, Richard J. CampTamarix as wildlife habitat

This chapter presents a “bird's eye” view of tamarisk and examines some issues surrounding the management of tamarisk in riparian woodlands. The focus on birds is based on the fact that they are a relatively well-studied group that can provide important insights into the role of tamarisk in riparian ecosystems. Because the decline of native riparian habitat occurred concurrently with the spread ofAuthorsMark K. Sogge, Eben H. Paxton, Charles van RiperOne year of migration data for a western yellow-billed cuckoo
In 2009, we studied the migration of the Western Yellow-billed Cuckoo by capturing 13 breeding birds on the middle Rio Grande, New Mexico, and attaching a 1.5-g Mk 14-S British Antarctic Survey geolocator to each bird. In 2010, we recaptured one of the cuckoos, enabling us to download its geolocation data. The cuckoo had flown approximately 9500 km during its southward migration, traveling throughAuthorsJuddson D.

The Kiwikiu (Pseudonestor xanthophrys), also called the Maui Parrotbill, is an endangered, forest bird found only in high elevation, wet forest of the eastern portion of Maui Island. Recent surveys, conducted at five year intervals, have revealed wide variation in abundance estimates (Camp et al. 2009). Effective management and conservation requires accurate estimates of abundance, which is diAuthorsKevin W. Brinck, Richard J. Camp, P. Marcos Gorresen, David L. Leonard, Hanna L. Mounce, Kelly J.
