Colony growth has varied widely among these islands, likely reflecting differences in immigration rates and local conditions, such as food availability and predation risk, which can influence breeding success and population dynamics. We assessed the breeding performance of Laysan Albatrosses on Clarion Island (2016\u20132023) in relation to foraging ecology and local predation. We monitored breeding success through periodic nest checks and quantified predation rates through focal observations. We tracked foraging trips using GPS devices and analyzed blood samples for stable isotopes (\n                    <jats:italic>\u03b4<\/jats:italic>\n                    <jats:sup>15<\/jats:sup>\n                    N,\n                    <jats:italic>\u03b4<\/jats:italic>\n                    <jats:sup>13<\/jats:sup>\n                    C). Over the study period, the colony experienced complete breeding failure. Our results suggest that two factors likely contributed to this outcome: (1) foraging limitations and (2) high predation rates. The remote location of Clarion Island required Laysan Albatrosses to travel farther to feeding grounds, potentially reducing the time available to acquire high\u2010quality prey. This may have influenced their dietary \u03b4\n                    <jats:sup>13<\/jats:sup>\n                    C signatures, which were associated with hatching success in our study. In addition, hatchlings experienced extremely high predation. Together, the apparent foraging constraints and intense local predation hindered successful reproduction and local recruitment. These factors may help explain the limited growth of the Clarion colony over recent decades. This study provides baseline data on the status of the colony and its main threats, which serve as critical input for planning conservation and management strategies.\n                  <\/jats:p>","DOI":"10.1002\/ece3.74346","type":"journal-article","created":{"date-parts":[[2026,10,1]],"date-time":"2026-10-01T06:07:02Z","timestamp":1790834822000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Breeding on a Tropical Island Proves More Difficult Than Expected: The Ongoing Breeding Failure of Laysan Albatross on Clarion Island"],"prefix":"10.1002","volume":"16","author":[{"given":"Jos\u00e9 Alfredo","family":"Castillo\u2010Guerrero","sequence":"first","affiliation":[{"name":"Departamento de Estudios Para el Desarrollo Sustentable de la Zona Costera, Centro Universitario de la Costa Sur Universidad de Guadalajara  San Patricio\u2010Melaque Jalisco Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandy Azucena","family":"Casta\u00f1eda\u2010Castellanos","sequence":"additional","affiliation":[{"name":"Departamento de Estudios Para el Desarrollo Sustentable de la Zona Costera, Centro Universitario de la Costa Sur Universidad de Guadalajara  San Patricio\u2010Melaque Jalisco Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel Arturo","family":"Portillo\u2010Zavala","sequence":"additional","affiliation":[{"name":"Departamento de Estudios Para el Desarrollo Sustentable de la Zona Costera, Centro Universitario de la Costa Sur Universidad de Guadalajara  San Patricio\u2010Melaque Jalisco Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salvador","family":"Hern\u00e1ndez\u2010V\u00e1zquez","sequence":"additional","affiliation":[{"name":"Departamento de Estudios Para el Desarrollo Sustentable de la Zona Costera, Centro Universitario de la Costa Sur Universidad de Guadalajara  San Patricio\u2010Melaque Jalisco Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8478-5575","authenticated-orcid":false,"given":"Guillermo","family":"Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Unidad Acad\u00e9mica Mazatl\u00e1n, Instituto de Ciencias del Mar y Limnolog\u00eda Universidad Nacional Aut\u00f3noma de M\u00e9xico  Mazatl\u00e1n Sinaloa Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,9,30]]},"reference":[{"key":"e_1_2_11_2_1","unstructured":"Agreement on the Conservation of Albatrosses and Petrels (ACAP).2010.\u201cEvaluaci\u00f3n de Especies por la ACAP: Albatros de Laysan (Phoebastria immutabilis).\u201dhttps:\/\/www.acap.aq\/es\/evaluacion\u2010de\u2010especies\/220\u2010albatros\u2010de\u2010laysan\/file."},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.5253\/078.099.0111"},{"key":"e_1_2_11_4_1","doi-asserted-by":"crossref","unstructured":"Awkerman J.
