Pelecanus
Species
conspicullatus
Threats/Control Methods - Regional
The nesting colonies are not well defended, as parents often leave their eggs unattended for hours at a time, loosing large numbers of birds to common predators. After a good breeding season, bird numbers may grow too high and many starve due to low food availability.
Threats/Control Methods - Local
Water bodies in urban areas are less resilient against periods of droughts or extreme weather events, causing a build-up of toxins and dangerous algae levels, which may impact the health of this species. In particular, the Jerrabomberra Creek Catchment, the home of many of the local Pelicans, is currently degraded from grazing, polluted stormwater from the Hume industrial estate, road surface runoff and rural residential developments.
Local/Urban Actions
It is important that our waterways remain free from pollution, to encourage healthy aquatic species. Joining in with a local Waterwatch activity can help improve water quality. At home, it is important avoid chemicals, pet faeces or garden waste going down the stormwater drain. Keep gutters clean and call the Canberra Connect helpline (02) 6207 9777 for specific chemical waste disposal information. Joining a Landcare revegetation activity around a local waterbodies will also improve the habitat areas for this species.
Common Names
Australian Pelican, Pelican, Spectacled Pelican, Australasian Pelican
Distinguishing Features
This large, unique-looking water bird is best known for its enormous pink bill with a soft pouch underneath. They have a body height of 1.6-1.8 metres, with a wingspan of 2.3-2.5 metres. Their head, neck and underparts are white, as are the large patches on their otherwise black wings. Their tail is black with a white 'V' shape across the rump. Breeding adults have a yellow tint across their breast and their bill becomes a deeper shade of pink. They have grey webbed feet and a yellow naked skin patch around their dark eye. Young birds are light brown where the adults are white.
Survey Techniques
Call and visual identification.
Species Call
Only calls in display or if fighting, giving a deep grunting 'orrh thu-thuh' or 'uh-uhhr'.
Similar Species
The Australian Pelican is extremely distict looking, although from a distance it may be confused with the White-bellied Sea-Eagle (Haliaeetus leucogaster).
Distribution
This waterbird is found right across Australia where salt or fresh water is available. Some birds travel to New Guinea, New Zealand or other small islands surrounding Australia.
Country of Origin
Australia
Conservation (Pet/Pest) Status - Regional
This species is uncommon around Canberra and may be declining. It is most likely to be seen at the Jerrabomberra Wetlands.
Conservation (Pet/Pest) Status - National
Secure, not listed under the EPBC Act 1999.
LSCCES Population
Some birds were sighted at the NMA, in Civic West, at BMP and on the ANU Campus.
Associated vegetation community
Any watered area is suitable for the Australian Pelican, including small freshwater ponds, swamps, lagoons and sheltered coastal bays.
Limiting Resources
This species requires a large area, sheltered on which to place a breeding colony. Only areas with adundant water, food and few predators will ensure a successful breeding season.
Breeding
The breeding season generally occurs over August to November, although it will breed in response to high water levels after a large rainfall event. They breed in colonies on small islands or on the sand banks of estuaries and lakes. The nest is a scrape on the ground, lined with vegetation. The 2-3 eggs are pure white and are incubated by both parents over 32-35 days. After a few weeks the young waddle out of the nest and join together in groups of up to a hundred young, being 'babysat' by only a few adults. The young birds are able to fly at about 12 weeks.
Behaviour
This species can travel long distances with long glides and occasional slow flapping. Flocks travel in a loose 'V' shape formation. They can be seen alone, although they are social birds, flying, loafing or feeding in small groups, sometimes working as a team to round up fish. They never dive under the water, just dipping their large bills into the water to trap any fish. Pelicans are clumsy when walking on the ground and taking off to fly requires a huge amount of effort. They do not breed in the Canberra region, travelling to large inland lakes or offshore islands where they display their bills by raising it and swinging it around with the pouch rippling.
Functional Group
Food Species
Australian Pelicans feed on a variety of fish and other aquatic animals.
Predators
Young birds at the nest and eggs are prone to attacks from many predators, including Black Rats (Rattus Rattus), Silver Gulls (Larus novaehollandiae ), Swamp Harriers (Circus aeruginosus) and Purple Swamphens (Porphyrio porphyrio ).
Interesting Fact
Fossil remains reveal that Pelicans have lived in Australia for at least 30-40 million years. Prehistoric birds were slightly smaller with shorter legs.
