Flying bird breeding colonies on Macquarie Island. This is a polygon dataset stored in the Geographical Information System (GIS). Attributes include the species name and the time of the year during which breeding occurs. The species include Black-browed Albatross, Grey-headed albatross, Southern Giant-Petrel and Wandering Albatross.

A GPS survey of seabirds on Heard Island during the Australian Antarctic Program's 2000/01 expedition. This layer is stored as two datasets (polygon and point) in the Geographical Information System (GIS). Polygon data represent flying bird and penguin colony extents. Point data represent nest locations and the location of the observation point for flying birds and penguins.

Metadata record for data from ASAC Project 1306 See the link below for public details on this project. ---- Public Summary from Project ---- The locations and characteristics of nest sites in the Larsemann Hills of three lesser-known seabird species will be mapped. Rapid survey techniques will be trialled and the diets and chronology of breeding determined. The influence of human activities on Broknes on skuas and other seabirds will be examined.

This dataset contains information on the distribution of Penguins and their breeding colonies in the Australian Antarctic sector, as of 1983. It forms Australia's contribution to the International Survey of Antarctic Seabirds (ISAS). The results are listed in the documentation. These include counts of chicks, adults and nests, as well as colony distribution maps. The survey includes Emperor Penguins, Adelie Penguins, King Penguins, Gentoo Penguins, Macaroni Penguins, Rockhopper Penguins, Chinstrap Penguins and Royal Penguins. Original data were taken from ANARE Research Notes 9. Only data from the Australian Antarctic Territory is described in this metadata record. Images of rough maps detailing the locations of each of the colonies are available for download from the url given below. Observation and count data have been incorporated into the Australian Antarctic Data Centre's Biodiversity Database. The data are presented in the format of Croxall and Kirkwood (1979) as recommended by the Report of the Subcommittee on Bird Biology held in Pretoria. In the tables all counts are estimates of the number of breeding pairs except where otherwise indicated. The numerical estimates and counts are of three kinds, indicated by the coded N, C or A: NESTS (N = count of NESTS or breeding/incubating pairs) The most accurate count of breeding pairs is that derived from a count of nests. This is usually carried out during incubation, but may also be made while chicks are still in the nest, before creches are formed. Such counts are only underestimates of breeding pairs by the number of breeding failures sustained between egg laying and the date of the count. CHICKS (C = count of CHICKS) Late in the breeding season the only counts possible are those of chicks. In general most pygosceild penguins raise one chick per pair per season, so a count of chicks gives a reasonable approximation of the original number of breeding pairs. However, season to season variation in breeding success can often be considerable. For example Yeates (1968) reports breeding success in Adelie Penguins at Cape Royds of twenty-six per cent, forty-seven per cent and sixty-eight per cent ever three seasons. Also, Macaroni Penguins only raise approximately 0.5 chicks per pair per season, so that chick counts of this species may be a considerable underestimate of the true breeding population. ADULTS (A = count of ADULTS) Many colony counts and estimates were expressed as total number of birds or adults. These figures are difficult to interpret as they depend on the time during the breeding season at which they were made. For some days prior to and until laying is finished, both birds of a pair will be present at the nest site while during incubation it is more likely that only one bird will be present. A further problem with counts of 'birds' is that they may include individuals who are not breeding and this gives an overestimate of the true breeding population. The counts of 'birds' or 'adults' which appear unqualified in log books have been divided by two to give an estimate of the number of breeding pairs. It must be stressed therefore that these counts are the least accurate. The degree of accuracy of these counts is inevitably highly variable and it is often difficult to ascertain on what basis a figure was arrived at. For the present survey counts have been allocated to one of five degrees of accuracy. Pairs/nests essentially individually counted. The count is probably accurate to better than + 5 per cent. Numbers of pairs in a known area counted individually and knowing the total area of the colony, the overall total calculated. This technique is useful for very large colonies. Accurate estimates; + 10-15 per cent accuracy. Rough estimate; accurate to 25-50 per cent. Guesstimate; to nearest order of magnitude. Many references are in the form ANARE (Johnstone) or simply ANARE. These refer to unpublished reports extracted from ANARE station biology logs. Those in the

Distribution and abundance of breeding seabirds in the AAT. This dataset comprises a broad range of component datasets derived from ground surveys aerial photography and oblique photography. Aerial and oblique photography has been used to obtain supplementary information on distribution and abundance of seabirds in the region. Recent surveys, 2000/01 onwards, have made use of GPS for more precise geographic information on seabird nests and colonies. At present there are a number of child metadata records attached to this record. See the link above for details.

Metadata record for data expected from ASAC project 131 (ASAC_131). Taken from the referenced publication: The diet of Heard Island cormorants was investigated by examination of casts over three summer seasons. The diet was composed of mainly benthic organisms, with polychaetes being the most common prey for the greater part of the population. Fish were taken commonly only by the small breeding population at the western end of the island, whereas elsewhere only 22% of casts contained any fish remains at all. The diet is therefore different from that reported for Phalacrocorax atriceps at other localities.
