Ecology of helminth parasitism in Puffinus gravis (Procellariiformes) on the breeding grounds at Gough Island
Great shearwaters, Puffinus gravis, on the breeding grounds at Gough Island in the central South Atlantic were hosts for seven species of gastrointestinal helminths (range, two to five species per host; abundance = 114–4016 parasites per host). Cestodes, including Tetrabothrius laccocephalus, Tetrab...

Great shearwaters had not previously been recognized as hosts for T. filiformis, T. diomedea, and Cardiocephaloides, while C. australe is reported for the first time in an avian host.
