Description General Info
Description
The hoary-headed grebe is a fairly small dark grey and white grebe. It has a brown eye and a black patch under the chin, and a narrow black streak down the back of the neck. During the breeding season the adult's plumage has white streaks over its entire head, giving them the common name of hoary-headed grebe. Juveniles have a white chin and throat and a striped face. Males have two plumage phases: after breeding they lose the buff breast and the white lines on the head, but can usually be identified then by the broad black bar down the nape.

Feeding Habits
Hoary-headed Grebe consumes aquatic arthropods via deep diving, favoring daytime feeding. During low light, hoary-headed Grebe forages at the water surface, showcasing adaptable feeding behaviors.
Habitat
Hoary-headed Grebe primarily inhabits open wetlands, including permanent or semi-permanent bodies of water. They favor habitats like large freshwater lakes, but can also be found on smaller farm pools and man-made tanks, particularly after heavy rainfalls. During winter, hoary-headed Grebe may venture into brackish or saline waters along sheltered bays, estuaries, creeks, and inlets. It is commonly found in regions that are unsheltered and lack dense water weed cover. This species adjusts to varying wetland habitats across geographically diverse areas, from the wetter regions to the typically arid interior following significant precipitation.
Dite type

Distribution Area
The hoary-headed grebe is found in all states and territories of Australia. It is generally absent from the central arid regions of Australia. The hoary-headed grebe is usually found away from the shoreline in large open waters, which may be estuarine, brackish or freshwater. It can also be found in sheltered coastal seas. It can sometimes be found in New Zealand, where it is much less common than Australia.
Species Status
With a large range and no evidence of significant population decline, this species’ conservation status is of Least Concern.
