From 30 December 1972 to 24 January 1973 records were kept of Adelie penguin activity at Hallet Station, Antarctica. A total of 312 hours of observation time was spent observing 13 penguins of various ages, Quantitative evidence is presented on the amount of time spent by members of each age group at their respective activities.

Feral pigeons bred in all months of the year but did less well in March when food was short. The most common clutch size, two, was also the most productive, 50% of eggs producing flying young. Clutches of one and four had significantly lower productivity. Clutches of one accounted for 15% of total clutches, three for 1% and four for 3%. Man seemed to be the only important predator of adult birds.

During 1965, 1406 sea birds and during 1966, 1102 sea birds were recovered from 1064 km and 785 km of New Zealand beaches. Monthly recovery rates indicated that sea bird mortality was usually higher in spring and summer (September to February) than in autumn and winter (March to August). Two wrecks were recorded during the two-year period, both on Wellington west coast beaches, and following periods of westerly or south-westerly winds. From September to December 1965 species affected included fairy prion, sooty shearwater, short-tailed shearwater, fluttering shearwater and diving petrel. In July 1966 there was a wreck of lesser broadbilled prions. Uncommon species found were blue petrel, Fiordland crested penguin, Pycroft’s petrel and Antarctic fulmar (all in 1965), and Arctic skua (in 1966).
