The Galapagos Penguin Spheniscus mendiculus (GAPE), Flightless Cormorant Phalacrocorax harrisi (FLCO), and Waved Albatross Phoebastria irrorata (WAAL) are marine birds that are endemic to the Galapagos Islands. To provide health information for these three species, baseline data on several physiological parameters were collected non-invasively—from individuals and populations appearing to be healthy—during the course of physical examinations that were conducted from 2011–2019. Heart rate, respiratory rate, body temperature, and body condition (weight vs. morphometric measurements) were analyzed as a function of age and sex. Mean heart rate differed significantly between juveniles and adults in all three species. Respiratory rate and body temperature varied with species, age, and sex; body condition index of GAPE, FLCO, and WAAL showed that males are heavier than females. We briefly speculate on the ecological context of these patterns.
