Circumpolar Distribution

Pintado or Cape Petrels Daption capense have a circumpolar distribution and have been recorded breeding at 23 localities in the Southern Ocean. They have been recorded as vagrants to Marion Island since 1951. Oosthuizen et al. (2009) regarded them as occurring too frequently for the species to be regarded as a vagrant, but was never thought to be breeding there. This is the first record of the species breeding at the PEIs and brings the number of seabird species, including the Lesser Sheathbill, reported breeding there to 31.

Invertebrate Biomass

Wandering albatrosses ( Diomedea exulans ) nest on Southern Ocean islands, building elevated nests upon which they incubate eggs and raise chicks, and which the chicks occupy through winter. The nests support high invertebrate biomass, including larvae of the flightless moth Pringleophaga marioni . Here we argue that high biomass of P. marioni in the nests is not associated with nutrient loading as previously suspected, but that higher temperatures in the nests increase growth and feeding rate, and decrease deleterious repeated cold exposure, providing fitness advantages for P. marioni. Thus, wandering albatrosses may be serving as thermal engineers, modifying temperature and therefore enabling better resource use by P. marioni.
