Hoary-headed Grebes are one of two small species of grebes in Australia. Their non-breeding plumage is dark brown-grey on the back nape of the neck and cap, near-white on the front of the neck, with a creamy-buff breast and near-white underparts. During the breeding season they grow black and white plumes covering most of the head, except a black stripe covering the length of the cap and the nape of the neck. Most of the bill, which in the non-breeding season is greyish, turns black in the breeding season, except for a cream-coloured tip. The eyes are pale, the legs and feet dark-grey.

The overall distribution of this species can be assessed based on sighting reports submitted by birdwatchers to ebird.org .

The global distribution of the Hoary-headed Grebe is available HERE .

Hoary-headed Grebes are endemic to Australia. They can be found basically anywhere on the Australian continent, including Tasmania, wherever there is surface water. They are only rarely found in the far tropical north of the continent and in the major deserts of western WA and the eastern parts of the NT and SA.

Hoary-headed Grebes mostly live in swamps and marshes around freshwater lakes and ponds, but also in estuaries. 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 rivers, creeks or on farm dams.

Sightings

A Hoary-headed Grebe was first seen by us on a farm dam near Watson's Creek, NSW, North of Tamworth, in July 2009.

Although, according to field guides, at least as common as Australasian Grebes, we do not see Hoary-headed Grebes regularly in inland NSW.

A single bird was found by us at Narrabri Lake, Narrabri, NSW, in July 2010.

A much larger number of Hoary-headed Grebes was found by us at Dangar's Lagoon, Uralla, NSW, in March 2012, together with a large number of Australasian Grebes.

Large numbers of both Hoary-headed Grebes and Australasian Grebes were also spotted by us in ephemeral wetlands 20 km South of Walgett, NSW, in June 2012. Some of those were in breeding plumage, in the middle of winter.

C. Hayne reports that Hoary-headed Grebes are regularly seen in various types of wetlands around Moree, NSW.

Various contributors report occasionally finding Hoary-headed Grebes in wetlands in Melbourne, VIC.

B. Hensen reports spotting Hoary-headed Grebes at Dangar's Lagoon near Uralla, NSW, in February 2013 and at Centennary Park, Sydney, NSW, in May 2013.

R. Plumtree reports spotting Hoary-headed Grebes at Ensay South, East Gippsland, VIC, in April 2014 and again in May 2016.

In December 2014 we spotted about 20 Hoary-headed Grebes on a small dam at the Burren Junction Bore Bath. In July 2016 a small number of Hoary-headed Grebes was spotted by us at Yarrie Lake, near Wee Waa, NSW.

H. Mouritsen reports spotting Hoary-headed Grebes at Yellow Waters billabong, Kakadu NP, NT, in October 2015.

BREEDING

Food, Diet

Hoary-headed Grebes usually dive to catch their prey, such as small aquatic creatures, including crustaceans but also insects.
