Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Australasian Grebe

Learn more about this article

The Australasian Grebe (Tachybaptus novaehollandiae) is a small waterbird common on fresh water lakes and rivers in greater Australia, New Zealand and on nearby Pacific islands. At 25-27 cm in length, it is one of the smallest members of the grebe family. (See also Little Grebe, Least Grebe.)

It is an excellent swimmer and diver, and usually dives immediately when alarmed and swims away under water.

Identification

Breeding plumage

Both sexes are dark brown above with a glossy-black head and neck and a striking chestnut facial stripe, extending from behind the eye to the base of the neck. The eye is yellow, with a prominent pale yellow face spot below.

Non-breeding

Both are generally duller, with no chestnut stripe, the face spot whiter, and throat and front grey-white. Similar to non-breeding Hoary-headed Grebes, which share a similar range.
