Assessing The Lgbtq+ Beliefs, Behaviors, And Competency Of Nutrition Professionals: A Mixed-Methods Study, Anthony Dissen, Christina Riccardo, Liam Oliver Lair Jul 2025

Assessing The Lgbtq+ Beliefs, Behaviors, And Competency Of Nutrition Professionals: A Mixed-Methods Study, Anthony Dissen, Christina Riccardo, Liam Oliver Lair

Journal of Dietetic Education

Lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ+) individuals often experience disproportionate levels of physical and mental health issues including nutrition-specific issues such as eating disorders, body dysmorphia, and food insecurity related to psychological distress from discrimination and stigmatization. This study sought to understand nutrition professionals’ LGBTQ+ competence, beliefs, and behaviors. Researchers distributed 2 data collection tools to registered dietitian nutritionists (RDNs): the Gay Affirmative Practice Scale (GAP-Scale) and the LGBT Competency Assessment Tool (LGBT-CAT). Data from the GAP-Scale were numerically scored using a 5-point Likert scale, and data from LGBT-CAT were scored on a scale of 0 to 3 points. …


Examining Weight Bias Attitude Changes After Exposure To A Brief Photovoice Assignment, Gretchen L. George, Hillary L. Roberts, Kristin Rose, Madison Clemens, Kate G. Burt Jul 2025

Examining Weight Bias Attitude Changes After Exposure To A Brief Photovoice Assignment, Gretchen L. George, Hillary L. Roberts, Kristin Rose, Madison Clemens, Kate G. Burt

Journal of Dietetic Education

Weight bias is present among pre-health professional students (e.g., nutrition, dietetics, nursing, physical therapy, medicine). Educators need support and guidelines about how to enhance learning through engaging assignments while also meeting accreditation requirements. This pilot study examined the impact of an innovative weight bias assignment using photovoice and reflection within existing nutrition education courses, measured through pre-post assessments from the Fat Attitudes Assessment Toolkit. While not all subscales showed significant change, improvements in the Fat Acceptance and Attribution Complexity Composites suggest these methods may be effective in shifting attitudes about fatness. Further research is needed to assess the long-term impact …

Development Of Dietetics Students’ Skills And Self-Efficacy In The Nutrition Care Process, Kristen Heitman, Marcia Nahikian-Nelms, Holly Estes-Doetsch, Kristen M. Roberts, Jennifer A. Garner, Julie Kennel, Christopher A. Taylor

Journal of Dietetic Education

The Nutrition Care Process (NCP) is a systematic framework for providing nutrition care and a cornerstone of dietetics practice. Dietetics education relies on development of skills to achieve competence and demonstrate readiness for practice. The relationship between development of fundamental skills and self-efficacy among dietetics students preparing for clinical practice remains unclear. The purpose of this study was to examine the development of dietetics students’ skills in NCP documentation and their self-efficacy in performing the skills over one academic year. Student nutrition notes (n = 120 notes, n = 30 students) from standardized patient encounters were evaluated for quality using …


Burnout And Turnover Among Program Directors In Acend-Accredited Registered Dietitian Nutritionist Programs, Heather Frazier, Patricia Grace-Farfaglia Jul 2025

Burnout And Turnover Among Program Directors In Acend-Accredited Registered Dietitian Nutritionist Programs, Heather Frazier, Patricia Grace-Farfaglia

Journal of Dietetic Education

Background: Knowledge about program director burnout in ACEND-accredited registered dietitian nutritionist programs is severely limited. Objective: To measure the changes in program director burnout and turnover over a two-year period. Methods: An online questionnaire was distributed to program directors via e-mail in 2021 and 2023. The validated Maslach Burnout Inventory-Educators Survey (MBI-ES) was used to measure burnout, which had three scales: emotional exhaustion, depersonalization, and personal accomplishment. Demographic and program information was also obtained. Results: Over the two-year period, program directors scores for emotional exhaustion (p < 0.001) and depersonalization (p < 0.001) significantly worsened. Interestingly, personal accomplishment scores significantly improved (p < 0.001) during the same time frame. Sixty-six percent of program directors in 2023 reported consideration for leaving their position in the next 5 years, which increased from 58%. Since 2021, 29.9% Didactic Program in Dietetics directors, 28.8% Dietetic Internship directors, and 37.5% Coordinated Program in Dietetics directors have resigned. Conclusion: Program directors show increased signs of burnout. Efforts are needed to investigate ways to support program directors to reduce burnout and increase retention of program directors.

Use Of An Honest Signal By Red-Footed Boobies Sula Sula In Response To Kleptoparasitism By Great Frigatebirds Fregata Minor, Lin Chao Jul 2025

Use Of An Honest Signal By Red-Footed Boobies Sula Sula In Response To Kleptoparasitism By Great Frigatebirds Fregata Minor, Lin Chao

Marine Ornithology

On Genovesa Island (00.3°N, 089.9°W) in the Galápagos Islands, Ecuador, Great Frigatebirds Fregata minor kleptoparasitize (i.e., steal food from) Red-footed Boobies Sula sula. In five of eight cases that I observed, the frigatebirds harassed the boobies until the latter regurgitated their forage, which the frigatebirds consumed. In three cases, the booby responded with a honk-like call and the frigatebirds stopped harassing. I propose that the honk is an “honest signal” by a booby having little food to divulge. Boobies loaded with forage do not honk because the call could trigger regurgitation. Thus, frigatebirds harass with escalation only non-honking boobies. The …


Confirmed Record Of Red-Footed Booby Sula Sula From Lakshadweep Sea, Northern Indian Ocean, Chullikad Lalan Vishnulal, Harichandran Prasitha Nisanth, Raveendhiran Ravinesh, Narayanane Saravanane Jul 2025

Confirmed Record Of Red-Footed Booby Sula Sula From Lakshadweep Sea, Northern Indian Ocean, Chullikad Lalan Vishnulal, Harichandran Prasitha Nisanth, Raveendhiran Ravinesh, Narayanane Saravanane

Marine Ornithology

The Red-footed Booby Sula sula occurs across tropical and subtropical oceans, nesting on islands and coastal areas. It is identified by its distinctive red feet, long wings, and sharp bill. However, confirmed reports are rare. Here we report, with photographs, the presence of a Red-footed Booby from the Union Territory of Lakshadweep, northern Indian Ocean. This record adds to the collective understanding of the species’ presence and distribution in the region.


White-Chinned Petrel Procellaria Aequinoctialis Feeding On A Dead Dolphin, Fabio Schunck, Rita Souza, Daniel N. Donadio, Leandro Correa, Rodrigo Bicudo, Miguel Oliveira De Souza, Pedro Giovani Cunha E Silva, Elenice Dias, Evair Legal, Fabio Barata Jul 2025

White-Chinned Petrel Procellaria Aequinoctialis Feeding On A Dead Dolphin, Fabio Schunck, Rita Souza, Daniel N. Donadio, Leandro Correa, Rodrigo Bicudo, Miguel Oliveira De Souza, Pedro Giovani Cunha E Silva, Elenice Dias, Evair Legal, Fabio Barata

Marine Ornithology

The White-chinned Petrel Procellaria aequinoctialis is an opportunistic forager that often follows fishing boats to feed upon scraps or escaped/discarded fish. Although its diet in non-breeding areas is not well understood, studies of stomach contents indicate that its diet consists of fish, crustaceans, and squid. In June 2024, during a pelagic birding trip off the coast of Santa Catarina State, Brazil, a White-chinned Petrel was spotted feeding on the floating carcass of a Franciscana Dolphin Pontoporia blainvillei. This behavior has not been previously documented in the literature, online citizen science platforms, or by personal observation. We believe this to be …


First Aberrant Coloured Calonectris Shearwater Recorded In Madeira, Portugal, Pedro Nascimento, Emanuel Santos, João Gonçalves, Mayung Teixeira Jul 2025

First Aberrant Coloured Calonectris Shearwater Recorded In Madeira, Portugal, Pedro Nascimento, Emanuel Santos, João Gonçalves, Mayung Teixeira

Marine Ornithology

Herein, we report a Calonectris sp. shearwater with aberrant plumage, observed southwest off Madeira Island. The bird had an unusual amount of white feathering, more than has been reported so far for the genus. Both upperparts and underparts were predominantly white. Initially, we thought the bird was a leucistic Cory’s Shearwater C. borealis, but some characteristics could not be ascertained. Records of such aberrations should be published to provide a more comprehensive understanding of the subject.


Absence Of Coronavirus In Terns In The Western Indian Ocean?, Camille Lebarbenchon, Chris Feare, Christine Larose, Marie-Alice Simbi, Solenn Boucher, Audrey Jaeger, Matthieu Le Corre Jul 2025

Absence Of Coronavirus In Terns In The Western Indian Ocean?, Camille Lebarbenchon, Chris Feare, Christine Larose, Marie-Alice Simbi, Solenn Boucher, Audrey Jaeger, Matthieu Le Corre

Marine Ornithology

We investigated coronavirus circulation in three tern species on four islands of the Western Indian Ocean (Bird, Reunion, Europa, Juan de Nova). None of the 2019 samples tested positive by reverse-transcription polymerase chain reaction. We discuss the implications of these findings in terms of host-species range, ecological drivers of virus transmission, and diagnostic tools.


Relative Abundance, Seasonal Occurrence, And Distribution Of Marine Birds In The Northern Gulf Of Mexico, J. Christopher Haney, Pamela E. Michael, Jeffrey S. Gleason, Randy R. Wilson, Yvan G. Satgé, Kathy M. Hixson, Patrick G.R. Jodice Jul 2025

Relative Abundance, Seasonal Occurrence, And Distribution Of Marine Birds In The Northern Gulf Of Mexico, J. Christopher Haney, Pamela E. Michael, Jeffrey S. Gleason, Randy R. Wilson, Yvan G. Satgé, Kathy M. Hixson, Patrick G.R. Jodice

Marine Ornithology

Marine birds in the U.S. Gulf of Mexico have long been poorly studied. Given statutory obligations to protect migratory birds and endangered species, three broad-scale vessel and aerial programs initiated since 2010 have now surveyed the entire northern Gulf. Vessel coverage alone exceeds 700 d and 74,000 km of observer effort using 300-m strip transects. We supplemented these survey data with earlier, smaller-scale studies, eBird checklists, literature reviews, and other less accessible sources to create snapshot summaries of relative abundance, seasonal occurrence, and regional distribution for 117 taxa of marine and water birds reported from the northern Gulf (113 of …


Status Of Craveri’S Murrelet Synthliboramphus Craveri In The Midriff Islands, Gulf Of California, Mexico, Francisco Jaime Martínez Reyes, Lauren A. Dolinski, Lorayne R. Meltzer, Paulina De L. Camarena Gomez, Noah L. Oas Jul 2025

Status Of Craveri’S Murrelet Synthliboramphus Craveri In The Midriff Islands, Gulf Of California, Mexico, Francisco Jaime Martínez Reyes, Lauren A. Dolinski, Lorayne R. Meltzer, Paulina De L. Camarena Gomez, Noah L. Oas

Marine Ornithology

The Craveri's Murrelet Synthliboramphus craveri is an endangered seabird (family Alcidae) endemic to northwestern Mexico, where it breeds on rocky islands throughout the Gulf of California (GOC). Nesting records are scarce for most of these islands, and much of the available information relies on historical data collected more than 50 years ago. Beginning in 2009 through to 2023, we performed intermittent nest searches on five islands in the Midriff Islands of the GOC. Starting in 2018 on Alcatraz Island and starting in 2022 on San Pedro Mártir Island, we monitored nests to determine average clutch size and hatching success. We …


First U.S. Atlantic Record Of Nazca Booby Sula Granti, With Implications For Vagrancy By Pacific Seabirds Into The Gulf Of Mexico, Kate E. Sutherland, Nicholas J. Metheny, J. Christopher Haney Jul 2025

First U.S. Atlantic Record Of Nazca Booby Sula Granti, With Implications For Vagrancy By Pacific Seabirds Into The Gulf Of Mexico, Kate E. Sutherland, Nicholas J. Metheny, J. Christopher Haney

Marine Ornithology

An adult Nazca Booby Sula granti was photographed in the western Gulf of Mexico on 03 August 2024 during a survey of marine birds and mammals over waters east of South Padre Island, Texas, USA (26.384ºN, 096.176ºW). This is the first report of S. granti in US waters of the Gulf of Mexico; previous eBird reports indicate occasional presence in Caribbean waters off Costa Rica (2018) and Colombia (2020). As many as 20% of all marine and waterbird species occurring in the Gulf of Mexico have core ranges in the Pacific Ocean or its continental margins. Dispersal by Pacific birds …


Nape Coloration Varies With Sex, Not Age, Among Great Shearwaters Ardenna Gravis, Ewan D. Wakefield, Anna R. Robuck, Kevin D. Powers, Robert A. Ronconi, Peter G. Ryan, David N. Wiley Jul 2025

Nape Coloration Varies With Sex, Not Age, Among Great Shearwaters Ardenna Gravis, Ewan D. Wakefield, Anna R. Robuck, Kevin D. Powers, Robert A. Ronconi, Peter G. Ryan, David N. Wiley

Marine Ornithology

Most petrels (family Procellariidae) exhibit little or no obvious variation in plumage with age or sex, either because plumage performs no sexual function or does so in a way poorly perceptible to humans. This limits the inferences that can be made from visual observations of petrels at sea. However, it has been suggested that nape coloration of Great Shearwaters Ardenna gravis whitens with age. Here we test this supposition using observations of known-age-class individuals. We necropsied birds bycaught around Gough Island, a major breeding colony in the South Atlantic Ocean, and in Massachusetts Bay, a wintering area off the northeastern …


A Petrel Breeding Diversity Hotspot: Raivavae Island (Austral Islands, French Polynesia), With A Need For Conservation Action, Vincent Bretagnolle, Yves David, Thomas Ghestemme, Jean-François Butaud, Tehani Withers, Hadoram Shirihai, Jean-Claude Thibault Jul 2025

A Petrel Breeding Diversity Hotspot: Raivavae Island (Austral Islands, French Polynesia), With A Need For Conservation Action, Vincent Bretagnolle, Yves David, Thomas Ghestemme, Jean-François Butaud, Tehani Withers, Hadoram Shirihai, Jean-Claude Thibault

Marine Ornithology

Raivavae is a small island in the Austral Islands of French Polynesia that is surrounded by a lagoon with 28 islets. Its marine avifauna is one of the least known and least studied in French Polynesia. Overall, seabird surveys in the various Austral Islands have been extremely sparse. This study addresses this need, using both historical and recent findings. The results show high species richness, with 10 breeding procellarid species, though none are numerous. We also update the knowledge on breeding petrels from other Austral Islands (except Rapa) and discuss the consequences of these findings in terms of their conservation …


Cruising For Data: Defining The Seabird Community From Vessels Of Opportunity In Canada’S Eastern Arctic, Carina Gjerdrum, Sarah N. P. Wong, Mark L. Mallory Jul 2025

Cruising For Data: Defining The Seabird Community From Vessels Of Opportunity In Canada’S Eastern Arctic, Carina Gjerdrum, Sarah N. P. Wong, Mark L. Mallory

Marine Ornithology

Information on marine bird abundance and distribution at sea is required to identify important habitat for protection, mitigate pressures from human activities, and understand the role of seabirds in marine food webs. Arctic waters support millions of marine birds, including globally significant numbers of some species, but the remote location coupled with the financial costs of research and monitoring in this region limit our ability to quantify marine habitat use. We used standardized survey data collected from vessels of opportunity during 2007-2023 to describe the distribution and abundance of marine birds in eastern Canadian Arctic waters and to examine the …

Spatial And Temporal Variation Of Beached Birds In Northern Argentine Patagonia, Victoria Magdalena Pizá, Patricio Javier Pereyra, Juan Pablo Seco Pon

Marine Ornithology

Beached birds on marine coastal beaches, along with other megafauna, are a valuable source of biological information, offering insights into species occurrence and factors that negatively affect their populations. The main objective of this study was to evaluate the spatial and temporal variation, and species composition, of coastal and marine birds found on sandy beaches in the Bahía de San Antonio Protected Natural Area (Río Negro Province, Argentina), and to relate resulting species abundance and richness to oceanographic and environmental variables. A biweekly survey was carried out over two years (2020-2022), during which 672 beached birds were recorded. The overall …


Thick-Billed Murres Uria Lomvia At Cape Parry, Northwest Territories: Core-Use Areas, Morphometrics And Chick Diets, Rosana Paredes, Stephen, J. Insley, Sebastian Luque, Piia Kortsalo Jul 2025

Thick-Billed Murres Uria Lomvia At Cape Parry, Northwest Territories: Core-Use Areas, Morphometrics And Chick Diets, Rosana Paredes, Stephen, J. Insley, Sebastian Luque, Piia Kortsalo

Marine Ornithology

Cape Parry is home to the only colony of Thick-billed Murres Uria lomvia in the western Canadian Arctic, but ecological information for this small, isolated population is lacking. To address this information gap, we investigated the spatial distribution, diving behaviour, diet, and morphometrics of male and female Cape Parry Thick-billed Murres during the breeding season. We tracked 23 chick-rearing adults (seven females and 16 males) using Global Positioning System (GPS) tags with depth sensors (2021) and collected chick diet data (2021, 2022) using observations and photos. Cape Parry murres foraged relatively close to the colony (4.5 ± 3.3 km) and …


Hybridization In Terns: A Review, Jente Ottenburghs, Ian C.T. Nisbet Jul 2025

Hybridization In Terns: A Review, Jente Ottenburghs, Ian C.T. Nisbet

Marine Ornithology

Hybridization—the interbreeding of different species—is a relatively common phenomenon in birds, but its study is biased towards certain taxa. In this review, we focus on a bird group that has received less attention: terns (Laridae, Sterninae). Based on an extensive literature search, we found records for 16 hybrids between tern species, with varying levels of supporting evidence: ten cases had strong support, one had medium support, one had low support, and four cases were deemed unreliable (two were refuted and two could not be evaluated). The strongly supported hybrid records involved 14 different tern species (out of 41 species, 34%). …


Seagrass And Mangroves As Water-Associated Bird Habitat In The Southern Red Sea Coasts Of Saudi Arabia, Jeff Bogart R. Abrogueña, Iwao Tanita, Anthony M. Doyle, Romana Roje-Busatto, Jean Rose H. Maquirang, Seerangan Manokaran, Khalid Imam, Thamer Al-Johani, Sau Pinn Woo Jul 2025

Seagrass And Mangroves As Water-Associated Bird Habitat In The Southern Red Sea Coasts Of Saudi Arabia, Jeff Bogart R. Abrogueña, Iwao Tanita, Anthony M. Doyle, Romana Roje-Busatto, Jean Rose H. Maquirang, Seerangan Manokaran, Khalid Imam, Thamer Al-Johani, Sau Pinn Woo

Marine Ornithology

Studies on water-associated bird communities within seagrass and mangrove habitats, especially in arid environments, are limited. Here, we studied a pristine mangrove forest with associated seagrass meadows in the Jazan City for Primary and Downstream Industries (JCPDI) on the southern Red Sea coast of Saudi Arabia. Our objectives were to (1) determine the differences in the diversity and distribution of water-associated bird communities between three sampling stations—S1 (a mixture of mangroves and seagrass beds), S2 (an open coast adjacent to mangroves), and S3 (an open coast without vegetation)—and across three seasons (March for spring, July for summer, and November for …


Wire Ingestion By A Red-Billed Tropicbird Phaethon Aethereus Chick On San Pedro Mártir Island, Mexico, Alberto Piña-Ortiz, Vladislav Marcuk, Salvador Gómez-Hernández, José Alfredo Castillo-Guerrero, Petra Quillfeldt Jul 2025

Wire Ingestion By A Red-Billed Tropicbird Phaethon Aethereus Chick On San Pedro Mártir Island, Mexico, Alberto Piña-Ortiz, Vladislav Marcuk, Salvador Gómez-Hernández, José Alfredo Castillo-Guerrero, Petra Quillfeldt

Marine Ornithology

We report the ingestion of wire by a Red-billed Tropicbird Phaethon aethereus chick at San Pedro Mártir Island, Gulf of California, Mexico. A scat sample collected from a four- to five-week-old chick contained a copper wire ~5.0 mm in length. Biologging revealed the previous foraging trips by one of the parents, and we ascertained the diet of birds in this colony through a molecular approach. From these data, we suggest why this individual was fed wire.


The Owl Gull: Exclusively Nocturnal Foraging By The Swallow-Tailed Gull Creagrus Furcatus In Galápagos, Sebastian M. Cruz, Luke R. Halpin, Carolina Proaño, David J. Anderson, Martin Wikelski Jul 2025

The Owl Gull: Exclusively Nocturnal Foraging By The Swallow-Tailed Gull Creagrus Furcatus In Galápagos, Sebastian M. Cruz, Luke R. Halpin, Carolina Proaño, David J. Anderson, Martin Wikelski

Marine Ornithology

Colony-based observations indicate that Swallow-tailed Gulls Creagrus furcatus go to sea only at night. Here, we use GPS tracking technology to reveal the species’ exclusively nocturnal foraging behavior at four colonies in the Galápagos Islands. All nocturnal trips proved to be foraging effort in pelagic waters 19–103 km from nests during breeding. While at sea, individuals spent approximately one-quarter of their time commuting, with half of the time dedicated to area-restricted search behavior. Three years of data from one colony indicate spatial fidelity to a general foraging area. Our research directly confirms that Swallow-tailed Gulls are the only obligate nocturnal …


Comparison Of Offspring Growth Models In Atlantic Puffins Fratercula Arctica , Katja H. Kochvar, Raul Zabala Belenguer, Pierre-Paul Bitton Jul 2025

Comparison Of Offspring Growth Models In Atlantic Puffins Fratercula Arctica , Katja H. Kochvar, Raul Zabala Belenguer, Pierre-Paul Bitton

Marine Ornithology

Growth of morphological traits in the offspring of many seabirds, including Atlantic Puffins Fratercula arctica, has typically been characterized by linear models despite displaying nonlinear patterns. We assessed the fit of six typical avian growth models to measurements of puffling mass, wing length, and tenth primary length. Across all three biometrics, the first- and second-best performing models were nonlinear (i.e., quadratic, logistic, extreme value function); these models were then used to generate separate growth curves for individual pufflings and extract easily interpretable and comparable parameter estimates. We recommend the reported models in future studies incorporating metrics of puffling growth and …


Artificial Brood Parasite Technique For Rearing Abandoned Eggs Of The Endangered Little Tern Sternula Albifrons, Masaharu Hayakawa Jul 2025

Artificial Brood Parasite Technique For Rearing Abandoned Eggs Of The Endangered Little Tern Sternula Albifrons, Masaharu Hayakawa

Marine Ornithology

The Little Tern Sternula albifrons is a ground-nesting species classified as Endangered on the Japan Ministry of the Environment's Red Data List. It may abandon its eggs owing to disturbances, a factor having a negative impact on its population trends. Successful artificial nurturing of these eggs could aid in the recovery of the species. To address this issue, I developed a ‘brood parasite' technique. The process involves taking abandoned eggs from a nest, incubating them in a facility until one day before hatching, and then covertly placing the protected eggs into other nests within the colony. By these means, foster …


Breeding Season Movements Of Aleutian Terns Onychoprion Aleuticus: Implications For Population Assessment And Monitoring, Kelly Nesvacil, Grey W. Pendleton, John P. Skinner, Susan Oehlers, Jeff Mondragon, Donald E. Lyons Jul 2025

Breeding Season Movements Of Aleutian Terns Onychoprion Aleuticus: Implications For Population Assessment And Monitoring, Kelly Nesvacil, Grey W. Pendleton, John P. Skinner, Susan Oehlers, Jeff Mondragon, Donald E. Lyons

Marine Ornithology

In 2017 and 2018, satellite transmitters were deployed (n2017 = 13, n2018 = 14) on Aleutian Terns Onychoprion aleuticus in two areas of Alaska, USA, to investigate breeding season movements and temporal patterns of colony activity. The effort was intended to aid in the development of a large-scale population-assessment framework. Across the two years, we observed dispersal to seven confirmed or potential (putative) colonies, none of which were previously documented, ranging in distance from 0.4 to 64.2 km from tag deployment sites. Although most terns did not associate with any known colonies during the breeding season, several individuals from the …


Modeling Breeding Habitat Preferences Of Tahiti Petrel Pseudobulweria Rostrata On Ta‘Ū, American Samoa, A. J. Titmus, C. A. Lepczyk Jul 2025

Modeling Breeding Habitat Preferences Of Tahiti Petrel Pseudobulweria Rostrata On Ta‘Ū, American Samoa, A. J. Titmus, C. A. Lepczyk

Marine Ornithology

Understanding the prevalence and use of breeding habitat of seabird species is important for evaluating appropriate conservation and management strategies. Seabirds are one taxonomic group for which we have relatively few species distribution studies, particularly on remote islands. To address this limitation, the goals of this study were to (1) build and use a species distribution model to identify which differences in habitat structure, physical characteristics, and environmental conditions affect Tahiti Petrel Pseudobulweria rostrata nesting presence on the island of Ta‘ū, American Samoa; and (2) evaluate how important nesting habitat characteristics can identify the fine-scale extent and location of suitable …
