The New South Wales Albatross Study Group (NSWASG) was an amateur ornithological fieldwork group that banded albatrosses and other seabirds off the coast of eastern New South Wales, Australia. Primarily targeting winter feeding aggregations of wandering albatrosses near Sydney, it developed its own catching methods and initiated what has become the longest-running continuous albatross research study in the world.

History

Origins

The origins of the NSWASG lie in the pioneer albatross banding activities started by Doug Gibson and Allan Sefton in 1956 at Bellambi in the Illawarra region, and by Bill Lane and Harry Battam in 1958 at Malabar, some 56 km further north in south-eastern Sydney. This followed the realisation that large concentrations of great albatrosses appeared in winter off the New South Wales coast not far from Sydney, and raised the possibility among local amateur ornithologists of catching useful numbers at sea for banding. Black-browed albatrosses also occurred in similar numbers, but wandering albatrosses were considered easier to catch because of their "more phlegmatic disposition", so the banding programs focussed on the latter. [1] At the time there were thought to be only two great albatross species – the wandering and royal albatrosses, with the royal (now split into northern royal and southern royal albatrosses) not known to occur along the coast of eastern Australia. The group, incorporating both banding programs, was formed in 1958 to operate as part of the Australian Bird Banding Scheme. [1] [2] Its objective was "to accumulate… as much information as possible concerning Diomedea exulans when at sea". [3]

Sites

The Bellambi site attracted large numbers of albatrosses because of the seasonal abundance of breeding aggregations of a favoured prey species, the Australian giant cuttlefish, with the albatrosses feasting both on live cuttlefish and the debris from predation by dolphins. [1] At Malabar the attraction was the presence of a major submarine sewage outfall which, during the 1950s, discharged large quantities of meaty and fatty wastes from abattoirs and tanneries and acted as a feeding station for albatrosses and other seabirds. According to local ornithologist Keith Hindwood, "Towards the end of April or early in May there is a large influx [of wandering albatrosses], and for the next six months it is not unusual to record from 100 to upwards of 400 birds close to the sewer outlets or resting on the water near the drift-line extending for half a mile or more from the cliffs". [4]

Methods

Catching albatrosses was only possible because, in light winds and while the birds were burdened with food, it was very difficult for them to take off from the water. Experiments began with the use of a metal triangle on a float; it was baited with cuttlefish meat to catch the albatross attempting to grasp the bait by the nail, or hooked tip of its upper mandible, and so draw it into a boat where it could be measured and banded. However, this method was slow and uncertain and it was replaced by the use of a hand-held hoop net, 1.35 m in diameter, which could be thrown over the bird as the boat approached it downwind while it struggled to become airborne. [1]

During the first 13 months of operations the group caught and banded 197 "wandering" and two black-browed albatrosses, 63% of which were caught at Bellambi. The group's first international recovery was of an adult male Wanderer, banded at Bellambi on 23 August 1958, which was present on Bird Island, South Georgia, in the South Atlantic Ocean, from 29 December 1958 to 6 March 1959. [1] In 1959 the group caught and banded 551 Wanderers, 21 of which were retraps from the previous year, as well as a bird banded in South Georgia. [3] By the end of the 1962 winter banding season, a total of 1238 Wanderers had been banded. Of these the proportion of retraps from previous years increased annually and it became clear that many birds returned each year. There were also many recoveries of banded birds in South Georgia. [5]

The group continued to operate for over thirty years despite the deaths of several of its founders and the end of Malabar as a suitable banding site with improvements in sewage treatment. As well as South Georgia, recoveries of albatrosses banded in New South Wales have been made in the Crozet Archipelago, the Prince Edward Islands, the Antipodes and Auckland Islands, with the body of research, which is ongoing, described as the longest continuous study of albatrosses anywhere in the world. [2] One product of the research was the Gibson Plumage Index, developed to categorise the variation in plumage colouring and, with the measurements, indicating differences between island populations. [3] [6]

The "Wanderer" group of albatrosses has been split into several taxa including, as well as the wandering albatross, the Antipodean, Gibson's, Tristan and Amsterdam albatrosses, not all of which are recognised by all authorities. Although the taxonomy is still in flux, the work of the group was instrumental in first indicating the genetic isolation of several island breeding populations. [7] The group was eventually subsumed into, and its work continued by, the Southern Oceans Seabird Study Association (SOSSA), established in 1994 by members of the NSWASG as an umbrella organisation for many groups involved in studies of the biodiversity of the Southern Ocean.

The snowy albatross, also known as the white-winged albatross, wandering albatross, or goonie, is a large seabird from the family Diomedeidae; they have a circumpolar range in the Southern Ocean. It is the most recently described species of albatross and was long considered to be the same species as the Tristan albatross and the Antipodean albatross. Together with the Amsterdam albatross, it forms the wandering albatross species complex. When the complex was split into four species, the English name of the nominate form was changed from wandering albatross to snowy albatross.

The Amsterdam albatross or Amsterdam Island albatross,, is a large albatross which breeds only on Amsterdam Island in the southern Indian Ocean. It was only described in 1983, and was thought by some researchers to be a subspecies of the wandering albatross, D. exulans. BirdLife International and the IOC recognize it as a species, James Clements does not, and the SACC has a proposal on the table to split the species. More recently, mitochondrial DNA comparisons between the Amsterdam albatross, the wandering albatross Diomedea exulans, the Antipodean albatross D. antipodensis and the Tristan albatross D. dabbenena, provide clear genetic evidence that the Amsterdam albatross is a separate species.

<span class="mw-page-title-main">Albatross</span> Family of large seabirds

Albatrosses, of the biological family Diomedeidae, are large seabirds related to the procellariids, storm petrels, and diving petrels in the order Procellariiformes. They range widely in the Southern Ocean and the North Pacific. They are absent from the North Atlantic, although fossil remains of short-tailed albatross show they once lived there up to the Pleistocene, and occasional vagrants are found. Great albatrosses are among the largest of flying birds, with wingspans reaching up to 2.5–3.5 metres (8.2–11.5 ft) and bodies over 1 metre (3.3 ft) in length. The albatrosses are usually regarded as falling into four genera, but disagreement exists over the number of species.

<span class="mw-page-title-main">Seabird breeding behavior</span>

The term seabird is used for many families of birds in several orders that spend the majority of their lives at sea. Seabirds make up some, if not all, of the families in the following orders: Procellariiformes, Sphenisciformes, Pelecaniformes, and Charadriiformes. Many seabirds remain at sea for several consecutive years at a time, without ever seeing land. Breeding is the central purpose for seabirds to visit land. The breeding period is usually extremely protracted in many seabirds and may last over a year in some of the larger albatrosses; this is in stark contrast with passerine birds. Seabirds nest in single or mixed-species colonies of varying densities, mainly on offshore islands devoid of terrestrial predators. However, seabirds exhibit many unusual breeding behaviors during all stages of the reproductive cycle that are not extensively reported outside of the primary scientific literature.

<span class="mw-page-title-main">Gibson's albatross</span> Subspecies of bird

Gibson's albatross, also known as the Auckland Islands wandering albatross or Gibson's wandering albatross, is a large seabird in the great albatross group of the albatross family. It is found principally in the Auckland Islands archipelago of New Zealand, foraging in the Tasman Sea, with most individuals nesting on Adams Island. The common name and trinomial commemorate John Douglas Gibson, an Australian amateur ornithologist who studied albatrosses off the coast of New South Wales for thirty years.

The Gibson Plumage Index (GPI), sometimes known as the Gibson Code, is a system for describing the plumage of great albatrosses. It is named after, and originally devised in the late 1950s by, John Douglas Gibson and other members of the New South Wales Albatross Study Group. Gibson was an Australian amateur ornithologist who carried out fieldwork on albatrosses along the coast of New South Wales for thirty years. The index assigns separate numerical values to the degrees of colouration on four parts of the body - the back, head, inner wing and tail - of albatrosses to indicate variations in age and between different breeding populations. For instance, a bird with a completely brown back would receive a score of 1 for the back, while a bird with an all-white back would be scored as a 6. The index was later expanded by Pierre Jouventin and colleagues to cover the more complex patterning of the Amsterdam albatross, adding belly and tibial feather colouration. This system for categorising the wide and complex variation in appearance of great albatrosses has been instrumental in the discovery of several genetically isolated populations and consequent description of new taxa, and has made field identification easier.
