Abstract:
The populations of Northern (Macronectes halli) and Southern Giant Petrel (Macronectes giganteus) in defined study areas on Bird Island have been monitored since 2000 and counts of colonies are carried out annually. The total number of breeding pairs of each species, and of mixed pairs (male Northern Giant Petrel x female Southern Giant Petrel), and the number of egg and chick failures are recorded. This allows calculation of hatching, fledging and overall breeding success. The number of chicks which are ringed and their subsequent survival is also recorded.
