ON THE WING

- WITH DON KNOWLER

The Wooden Boat Festival has come around again, an event I always associate with the legendary bird of the southern oceans, the albatross.

During the 2013 festival I actually saw the lanky shape of a shy albatross not 40m offshore of the Hobart docks. I thought at the time the albatross would make an apt symbol for the festival, particular­ly the shy albatross which breeds exclusivel­y on just a few Tasmanian islands.

I had been told many years previously that it was possible to see shy albatrosse­s in zigzag flight on the bay but I hardly believed it. Then during the festival I saw one on its slender wings riding the crests of waves on a particular­ly windy day. The waves were topped with white caps as the wind whipped up a spray, and tugged at the sails of the wooden boats docked in Constituti­on Dock.

Albatrosse­s are the great travellers of the seas with some species, like the bird with the world’s largest wingspan, the wandering albatross, circumnavi­gating the globe each year. The shy albatross lacks the giant size of the “wanderer”, falling into a category of medium-size albatrosse­s, the mollymawks.

Because albatrosse­s largely fish in remote seas, only coming ashore to breed on islands, they are rarely seen except by commercial fishermen working in harsh waters or by birdwatche­rs who mount pelagic birding trips. Such a birding excursion in Tasmania runs from Eaglehawk Neck, and attracts birdwatche­rs from all over the world.

Although birders revel in the sight of albatrosse­s plying the oceans, using the updraft from the waves to give them lift with a minimum of expended energy, the fishing industry has not been kind to these magnificen­t birds or to other pelagic species.

Two aspects of modern fishing are putting the albatross in peril. The first is longline fishing, in which lines sometimes kilometres long are strung out behind ships to catch fish. Albatrosse­s and other seabirds take the bait and are drowned.

Research by marine biologists suggest 100,000 albatrosse­s are killed this way annually, although in recent years great strides have been made in designing lines that sink below the surface, out of reach of albatross beaks. The use of these lines has also been mandated.

Another threat to the albatross is the discarding of fish offal from factory ships, which attracts the birds for a quick and easy feed. In such instances, instead of being drowned by fishing lines, the albatrosse­s are caught up in trawler nets and dragged to their deaths.

Of 22 species of albatross, all attract some level of concern, three being critically endangered. Among the world’s 346 seabird species, 97 (28 per cent) are globally threatened.
