1. A study on the siting, establishment and maintenance of territories in the South Polar Skua (Catharacta maccormicki) [K017_1967_1968_NZ_2]
A study of skua territories was conducted by examining siting, establishment and maintenance of territories in two very different conditions including in an area close to the penguins where skuas ...


2. Analysis of ecstatic calls displays and nest parameters and their importance in Adelie penguin mate attraction, pair bonding and nest success [K019_2002_2003_NZ_1]
Mate recognition of adelie penguins is crucial to their breeding success in such an extreme environment. The importance of male ecstatic display, the role of factors including nest location and size ...


3. Behavioural observations, recorded calls and breeding parameters as factors influencing the vocal behaviour of Adelie penguins (Pygoscelis adeliae) [K019_2000_2001_NZ_1]
Factors influencing the development and survival of Adelie penguins were investigated from the Cape Bird colony. The fieldwork focused on aspects of vocal recognition but parental care and chick development ...


4. Botanical investigations at Terra Nova Bay and Wood Bay, North Victoria Land and the assessment of human impacts [K271_1988_1989_NZ_1]
Vegetation and environmental studies were conducted at sites on Ross Island and in North Victoria Land, including Terra Nova Bay (Edmonson Point, Northern Foothills, Cape Washington, Mount Melbourne, ...


5. Causes of high mortality of the second chick from a pair of skua (Catharaeta maccormicki) eggs; egg content and chick weights, feeding rates, parental brooding behaviour, experimental removal and starvation of chicks [K017_1966_1967_NZ_1]
The cause/factors of heavy mortality of the second chick hatching from a pair of eggs at a skua nest was investigated. Previous observations found that the second chick is chased away from the nest ...


6. Measurements of the strength of an adult skua and the force required to drag an adelie penguin chick from a colony [K017_1968_1969_NZ_1]
How much force was necessary to drag struggling adelie penguin (Pygoscelis adeliae) chicks of different ages from a colony was measured by holding a chick in a harness as they tugged against a spring ...


7. Observations of intraspecific aggressive behaviour in the adelie penguin (Pygoscelis adeliae) [K017_1967_1971_NZ_1]
The cause, function, effect and patterns of behaviour in penguin fighting on the colony was determined from long periods of direct observations of banded penguins and on set-period recordings of all ...


8. The relationship between skuas and adelie penguins at the Cape Bird colonies: penguin egg and chick mortality from skua predation and territorial, feeding and breeding behaviour of skuas about the penguin colony [K017_1965_1970_NZ_1]
A five year study on the relationship between skuas (Catharaeta maccormicki) and adelie penguins (Pygoscelis adeliae) was investigated at Cape Bird with two studies: a) A study of penguin egg ...
