Australasian Grebe (Tachybaptus novaehollandiae) lives in freshwater lakes across Australia and New Zealand. Its conservation status is Least Concern.
Fascinating facts about the Australasian Grebe
- When alarmed, the Australasian grebe darts beneath the surface and resurfaces 10-15 metres away, preferring a swift underwater escape to a clumsy flight. This habit reflects its reputation as an excellent swimmer and diver, allowing it to evade predators while staying close to its feeding grounds.
- Both parents tend the young, but the male departs after a couple of months once the chicks are about three-quarters grown, leaving the female to finish rearing. The chicks ride on the parents' backs until they can dive and feed themselves at roughly 10 weeks, when the mother may briefly leave before often returning to check on them.
- The species splits into six recognized subspecies, each tied to a distinct island or region: T. n. javanicus on Java; T. n. fumosus on the Talaud & Sangihe Islands; T. n. incola in northern New Guinea; T. n. novaehollandiae across southern New Guinea, Australia, Tasmania & New Zealand; T. n. leucosternos in Vanuatu & New Caledonia; T. n. rennellianus on Rennell Island (Solomon Islands). This geographic mosaic shows how isolated water bodies drive subtle evolutionary tweaks within a single species.
- At just 25-27 cm (9.8-10.6 in) long, the Australasian grebe ranks among the tiniest grebes on Earth, sharing that pocket-size status with the least and little grebes.
- The Australasian grebe is a weak flyer and only undertakes nocturnal flights, likely to dodge daytime predators.

In the serene waters of Australia's wetlands, the Australasian Grebe glides effortlessly, its sleek, black-and-white feathers glistening like polished silk as it navigates the aquatic realm with an air of quiet confidence. With each gentle stroke of its powerful legs, the grebe propels itself forward, its bright, inquisitive eyes scanning the surroundings for the slightest hint of prey, its very existence a testament to the beauty of adaptation. As it dives beneath the surface, its slender body slices through the water with barely a ripple, a fleeting glimpse of a life lived in perfect harmony with the elemental forces that shape its world.
