Abstract
Blood chemical reference values and variations in them in longlived endangered birds are of metabolic veterinary ecological and/or taxonomic interest In the present study we for the first time provide such reference values and test the influence of sex age and nest location on up to 11 plasma values in nesting blackbrowed albatrosses Thalassarche melanophrys that we sampled in 2015 on the Falkland Islands Our results showed that differences between sexes were not significant for any of the parameters for which we tested We found insignificant differences in metabolically related parameters in nestlings being raised in the middle of nesting colonies and those being raised at the edges of the colonies indicating that nest location did not affect the nutritional status or health of young developing albatrosses Conversely age had a significant effect on a number of metabolites inorganic ions and enzymatic activity In particular agerelated differences in glucose triglyceride urea and uric acid suggested that the relative metabolic rate was higher in nestling than in adult albatrosses
