Trumpeter swan Hoopers; are the least." Early efforts to reintroduce this bird into other parts of its original range, and to introduce it elsewhere, have had modest success, as suitable habitats have dwindled and the released birds do not undertake migrations. More recently, the population in all three major population regions have shown sustained growth over the past thirty-year period. Data from the US Fish and Wildlife Service show 400% growth in that period, with signs of increasing growth rates over time. One impediment to the growth of the trumpeter swan population around the Great Lakes is the presence of a growing
Trumpeter whiting species was first scientifically described by Quoy and Gaimard in 1824 from specimens collected from the waters of Sydney Harbour in New South Wales, Australia. A specimen from this location was also designated to be the holotype. The species was subsequently redescribed under the name of "Sillago gracilis" by Alleyne and Macleay in 1877, which is a junior synonym and has been discarded under the ICZN rules. Roland McKay, whilst working on a revision of the sillaginids, found there to be three closely related species of 'trumpeter whiting'; the western trumpeter whiting, the oriental trumpeter whiting and the trumpeter whiting
