The hoary-headed grebe is a member of the grebe family. It breeds in southern parts of Australia; it winters throughout the island of Tasmania. The bird takes its name from the silvery-white streaking on its black head. It is common in Australia, with a population of about 500,000. Its habitat is similar to that of the Australasian grebe.
Region
Australia
Typical Environment
Found across southern mainland Australia and Tasmania wherever suitable open freshwater is available, including lakes, reservoirs, farm dams, and sheltered wetlands. It also uses brackish lagoons and estuaries, especially when inland waters dry. The species favors expanses of open water with patches of emergent vegetation for nesting and cover. Movements are often driven by rainfall and water levels, leading to local irruptions and dispersal.

The hoary-headed grebe gets its name from the fine silvery-white streaks across the dark head in breeding plumage, giving a frosted look. It breeds mainly in southern Australia and often disperses or moves seasonally to suitable waters, wintering commonly around Tasmania. Like other grebes, it builds floating nests anchored to aquatic vegetation and the chicks often ride on the parents’ backs. It is widespread and common, with a large population and flexible habitat use.
Temperament
social and active
Flight Pattern
short rapid wingbeats
Social Behavior
Often forms loose flocks on larger waterbodies outside the breeding season. Breeding is typically in pairs or small colonies, with floating nests anchored to reeds or other vegetation. Clutches usually contain several eggs, and downy chicks frequently ride on the parents’ backs for warmth and protection. Pairs are seasonally monogamous.
Migratory Pattern
Partial migrant
Song Description
Generally quiet, but gives sharp, metallic trills and chattering calls, especially during courtship and territorial displays. Calls can carry over open water and are often exchanged between partners at the nest.
Plumage
In breeding plumage, the head and nape are dark with dense silvery-white streaks, giving a hoary appearance; upperparts are brown and underparts pale. Non-breeding birds are plainer brown above with a dusky cap and whitish throat and face. Feathers are compact and waterproof, aiding diving.
Diet
Feeds primarily on aquatic insects and their larvae, such as beetles and dragonfly nymphs, along with small crustaceans. It also takes small fish, tadpoles, and other invertebrates opportunistically. Like other grebes, it sometimes swallows its own feathers, which may aid in protecting the stomach and forming pellets.
Preferred Environment
Forages by diving in open freshwater, often near the edges of emergent vegetation where prey is abundant. It searches underwater with quick, agile dives and short surfacings. It may also glean small prey from the water surface in calm conditions.
