Routine haematological investigations were carried out on 102 wild adult gr
eat skuas Catharacta skua. No sex- or age-related differences were detected
in any of the parameters measured. There are very few sets of haematologic
al reference ranges published for sea-birds from the northeastern Atlantic.
Given the recent pollution threats in this region, the reference ranges pr
esented for this species could be a valuable tool in future conservation ef
forts.
