Wikipedia Abstract

The hoary-headed grebe (Poliocephalus poliocephalus) is a member of the grebe family found in Australia and 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.
