Physical description Click here for a physical description Australasian Grebes are one of two small species of grebes in Australia. During the non-breeding season their plumage is dark brown on the back and light brown on the flanks, and whiteish around the vent. During the breeding season the cap of the head and the throat turns black, while part of the back of the neck turns chestnut-brown. The bill turns all-black, with a light-yellow spot on the gape. The eyes are yellow, the legs and feet dark-grey. Chicks and juveniles have a striped pattern on their cheeks and, when young, over their entire body, and an orange bill.

Taxonomy, classification See Australasian Grebe at Wikipedia .

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Australasian Grebe is available HERE . There are several races of Australasian Grebes, whose range extends from Indonesia (Java), via New Guinea and nearby Pacific Islands into Australia and New Zealand. Australasian Grebes, race "novaehollandiae", can be almost anywhere on the Australian continent, including Tasmania, wherever there is fresh surface water, although in times of drought they will avoid the most arid parts of the interior. They are also found on Lord Howe Island. They can be found in almost any type of water - even a small, bare small/farm dam without vegetative fringe will do. Although in principle also present in the arid centre, they will stay there only if/when there is reliable surface water, e.g. in permanent waterholes in watercourses or on farm dams. Where to look? How to find this species? Australasian Grebes are content with very little in terms of water surface to live on - they can potentially be found even on small lakes and farm dams, also in in urban parks - check open water surfaces when the area is undisturbed; look closer to the edges of reeds and other vegetation if there are disturbances around the water's edge.

Sightings Click here for sighting information Race "novaehollandiae" Australasian Grebes, race "novaehollandiae", can be found regularly on water surfaces in large parts of NSW, including inland areas. Australasian Grebes, race "novaehollandiae", are satisfied with very little water. Even small dams, some 20x20 m in size, are sufficient for the birds to populate. Only during the breeding season protective reeds and/or islands are required. In September 2008 a pair settled in for a while on the reed-overgrown small dams of our property at Eulah Creek, 20 km East of Narrabri. A pair bred there successfully in 2011/12. In June 2012, in the middle of winter, many Australasian Grebes, race "novaehollandiae" seen by us in ephemeral wetlands near Walgett, NSW, were still (or already) in breeding plumage. We have also received reports of Australasian Grebes, race "novaehollandiae", from various parts of both QLD and VIC. J. Greaves reports Australasian Grebes, race "novaehollandiae", breeding at Lake Claremont, Perth, WA, in January 2015. J. Greaves reports spotting Australasian Grebes, race "novaehollandiae", at the Granites Gold Mine, inland NT, in June 2015, and on Kangaroo Island, SA, in March 2016. H. Mouritsen reports spotting Australasian Grebes, race "novaehollandiae", at Fogg Dam NR, NT, in October 2015, and at Knuckey's Lagoon, near Darwin, NT, in July 2018. Australasian Grebes, race "novaehollandiae", have also been reported to us from various locations in VIC. P. Brown reports spotting Australasian Grebes, race "novaehollandiae", at the Leanyer Sewage Ponds, Darwin, NT, in July 2021. C. Pears spotted Australasian Grebes, race "novaehollandiae", at Lake Herdsman, Perth, WA, in April 2021. Since then they are found there regularly.

Breeding information

Breeding season: Oct - Jan

Eggs: 4 - 5

Incubation period: 21 - 24 days

Fledging age: 42 - 49 days

The breeding season depends significantly on geographical latitude. In the tropical north Australasian Grebes breed Dec - Apr. Also in other areas the breeding season may extend into autumn. At Eulah Creek a pair was observed raising three chicks that hatched in March 2013.

Nest

"bungobittah", "lar", "malunna", "jindi" [bundjalung] = nest [Aboriginal]

Type: Basket

Material: Aquatic plants

Height above ground: N/A

Nests usually are floating platforms on water surface, anchored to reeds.

Eggs

"boyanga", "booyanga", "derinya", "dirandil", "koomura", "mirk", "ngampu", "nooluk", "pateena", "pum-pum" = Egg; "dirundirri" = eggs [Aboriginal]; "gawu" = eggs [gamilaraay]

Size: 36 x 25 mm

Colour: Light-brown to dark-brown

Shape: Tapered oval

Due to their absorbent surface, eggs darken significantly during incubation.

Australasian Grebes can re-surface after a dive with only the head showing above water - this way they are very hard to spot when caught out on open water without vegetation for protective cover

Food, Diet

Australasian Grebes usually dive to catch their prey, such as small aquatic creatures including crustaceans, up to several metres under water. We have also seen them take insects at the water surface.
