Yellow-billed spoonbill
The yellow-billed spoonbill (Platalea flavipes) is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is native to Australia, and is a vagrant to New Zealand, Lord Howe Island and Norfolk Island. Taxonomy The renowned ornithologist John Gould first described the yellow-billed spoonbill, naming it Platalea flavipes although noting its distinctness from other members of the genus. Bonaparte erected the genus Platibis in 1856, and Gould followed this classification in his later work. He noted the species appeared in great numbers across New South Wales in 1839, particularly in the north between the Hunter and lower Namoi Rivers. The year had been wet, in contrast to droughts in previous years. A 2010 study of mitochondrial DNA of the spoonbills by Chesser and colleagues found that the yellow-billed and roseate spoonbills were each other's closest relative, and the two were descended from an early offshoot from the ancestors of the other four spoonbill species. They felt the genetic evidence meant it was equally valid to consider all six to be classified within the genus Platalea or alternatively the two placed in the monotypic genera Platibis and Ajaia respectively. However, as the six species were so similar morphologically, keeping
