Distribution. The Whooper breeds in the extreme north of Europe and Asia, and visits most parts of Europe and temperate Asia in the winter.
A single specimen of a Swan was obtained by Hodgson in the Nepal Valley in January 1829. The skin was lost; but a drawing was kept, and also the skull and a foot; the latter two are now in the British Museum, and the drawing in the Library of the Zoological Society. By G. R. Gray and Brooks the species was recognized as G. ferus (musicus) ; but Hume identified the figure with the smaller species G. bewicki on account of the Coloration of the bill. I have examined all the evidence, and whilst the drawing, on which no dimensions are noted, appears to me less carefully drawn than most of Hodgson's figures, and to leave some doubt as to which species is represented, the skull and feet, which Mr. Grant has been so good as to compare with me, are much too large for 0. bewicki, and undoubtedly belonged to G. musicus.
