The Galápagos blue-footed booby () is a sulid species endemic to the Galápagos archipelago. Here we present physical examination, breeding status, hematology, and blood chemistry results from 60 Galápagos blue-footed boobies that were captured by hand from their nesting site on North Seymour Island in June 2017 and July 2022. A portable blood analyzer (iSTAT) was used to obtain values in the field for hematocrit, hemoglobin, sodium, potassium, chloride, ionized calcium, total CO, glucose, blood urea nitrogen, creatinine, and anion gap for each bird.
