It has breeding areas in the tropical Atlantic Ocean and the Pacific Ocean (extending along Central America up to Baja California) (Schreiber &amp; Burger, 2001). The <jats:italic>Fregata magnificens magnificens<\/jats:italic> (MFB-Gal) subspecies is native to the Gal\u00e1pagos Islands. This is the first-time hematology and blood chemistry parameters have been published for the <jats:italic>F. m. magnificens<\/jats:italic> (MFB-Gal) from the Gal\u00e1pagos Islands. Analysis was run on blood samples drawn from <jats:italic>n<\/jats:italic> = 16 adult MFB-Gal captured by hand at their nests at North Seymour and Daphne Major Islands in the Gal\u00e1pagos Islands (<jats:italic>n<\/jats:italic> = 10 MFB-Gal in June 2017 and <jats:italic>n<\/jats:italic> = 6 MFB-Gal in July 2022). There were ten female birds and six male birds in total. A portable blood analyzer (iSTAT) was used to obtain near immediate field results for total carbon dioxide (TCO<jats:sub>2<\/jats:sub>), hematocrit (Hct), hemoglobin (Hb), sodium (Na), potassium (K), chloride (Cl), ionized calcium (iCa), total protein (TP), anion gap and glucose. Blood lactate was measured using a portable Lactate Plus\u2122 analyzer. Average heart rate, respiratory rate, body weight, body temperature, biochemistry and hematology parameters were comparable to healthy individuals of other Fregatidae of the same species (magnificent frigatebird subspecies from Brazil, <jats:italic>Fregata magnificens<\/jats:italic>, likely <jats:italic>F. m. rothschildi<\/jats:italic>) or similar species (great frigatebird, <jats:italic>Fregata minor<\/jats:italic>, from the Gal\u00e1pagos Islands). There were some statistically significant differences between the males and females <jats:italic>F. m. magnificens<\/jats:italic> (MFB-Gal) in the Gal\u00e1pagos, including bill depth, bill width, wing length, weight, and chloride blood value. The reported results provide baseline data that can be used for comparisons among populations and in detecting changes in health status among Gal\u00e1pagos magnificent frigatebirds and other populations of magnificent frigatebirds.<\/jats:p>","DOI":"10.7717\/peerj.18609","type":"journal-article","created":{"date-parts":[[2024,12,6]],"date-time":"2024-12-06T09:04:22Z","timestamp":1733475862000},"page":"e18609","source":"Crossref","is-referenced-by-count":0,"title":["Health status and morphometrics of Gal\u00e1pagos magnificent frigatebirds (<i>Fregata magnificens magnificens<\/i>) determined by hematology, biochemistry, blood gas, and physical examination"],"prefix":"10.7717","volume":"12","author":[{"given":"Kimberly E.","family":"Guzm\u00e1n","sequence":"first","affiliation":[{"name":"Oradell Animal Hospital, Paramus, New Jersey, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diane","family":"Deresienski","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, Universidad San Francisco de Quito, Quito, Ecuador"},{"name":"Clinical Sciences, North Carolina State University, Raleigh, NC, United States"},{"name":"Galapagos Science Center, Universidad San Francisco de Quito, Puerto Baquerizo Moreno, Galapagos, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9792-5653","authenticated-orcid":true,"given":"Juan Pablo","family":"Mu\u00f1oz-P\u00e9rez","sequence":"additional","affiliation":[{"name":"Galapagos Science Center, Universidad San Francisco de Quito, Puerto Baquerizo Moreno, Galapagos, Ecuador"},{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales COCIBA, Universidad San Francisco de Quito USFQ, Quito, Ecuador"},{"name":"Biology, University of the Sunshine Coast, Sippy Downs, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ronald K.","family":"Passingham","sequence":"additional","affiliation":[{"name":"Clinical Sciences, North Carolina State University, Raleigh, NC, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alice","family":"Skehel","sequence":"additional","affiliation":[{"name":"Biological Sciences, University of the Sunshine Coast, Sippy Downs, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catalina","family":"Ulloa","sequence":"additional","affiliation":[{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales COCIBA, Universidad San Francisco de Quito USFQ, Quito, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina","family":"Regalado","sequence":"additional","affiliation":[{"name":"Universidad San Francisco de Quito, Quito, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0716-1387","authenticated-orcid":true,"given":"Gregory A.","family":"Lewbart","sequence":"additional","affiliation":[{"name":"Clinical Sciences, North Carolina State University, Raleigh, NC, United States"},{"name":"Galapagos Science Center, Universidad San Francisco de Quito, Puerto Baquerizo Moreno, Galapagos, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5523-634X","authenticated-orcid":true,"given":"Carlos A.","family":"Valle","sequence":"additional","affiliation":[{"name":"Galapagos Science Center, Universidad San Francisco de Quito, Puerto Baquerizo Moreno, Galapagos, Ecuador"},{"name":"Colegio de Ciencias Biol\u00f3gicas y Ambientales COCIBA, Universidad San Francisco de Quito USFQ, Quito, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4443","published-online":{"date-parts":[[2024,12,6]]},"reference":[{"issue":"4","key":"10.7717\/peerj.18609\/ref-1","doi-asserted-by":"publisher","first-page":"512","DOI":"10.1016\/j.cbpb.2005.03.001","article-title":"Age-dependent changes in plasma biochemistry of Yellow-legged Gulls (Larus cachinnans)","volume":"140","author":"Alonso-Alvarez","year":"2005","journal-title":"Comparative Biochemistry and Physiology Part A"},{"issue":"6145","key":"10.7717\/peerj.18609\/ref-2","doi-asserted-by":"publisher","first-page":"514","DOI":"10.1126\/science.1239401","article-title":"Climate change and infectious diseases: from evidence to a predictive framework","volume":"341","author":"Altizer","year":"2013","journal-title":"Science"},{"issue":"5","key":"10.7717\/peerj.18609\/ref-3","doi-asserted-by":"publisher","first-page":"e97185","DOI":"10.1371\/journal.pone.0097185","article-title":"Haemoproteus iwa in great frigatebirds (Fregata minor) in the islands of the Western Indian Ocean","volume":"9","author":"Bastien","year":"2014","journal-title":"PLOS ONE"},{"article-title":"Fregata magnificens.
