INDIAN DUCKS AND THEIR ALLIES. 15 



giving widely different measurements, both of which also differ from 

 that given by Salvadori. 



The female is some few inches smaller than the male, with a wing 

 about 19". Naumann gives the following dimensions for a female. 

 Length 30'8", expanse 73*0", wing 18"6". 



Young birds of the second season are white, with the head and breast 

 much marked or suffused with rusty ; the base of the bill is a dull 

 lemon-yellow. 



Birds of the first winter are greyish-brown, and have the base of the 

 bill a dull fleshy yellow, whilst the feet are not black but are of a 

 dull reddish colour. The irides are said not to be of so bright a brown 

 as in the adult bird. 



I can find no record of the nestling of this species, which, however, 

 is almost sure to be white. 



This swan is said to be an Indian visitor on the strength of the 

 same evidence brought forward to prove the finding of C. musicus in 

 India, but with, I think, far greater probability of being correct in the 

 ease of C. bewicki. That it is of the very rarest occurrence is, however, 

 proved by the fact that no others have been recorded. The skull and 

 feet of the bird obtained by Hodgson in Nepal are in the British 

 Museum, but the skin, as I have already mentioned, is lost, having 

 been destroyed by insects. 



This is more of a British bird than the whooper, at the same time 

 less, perhaps, of an European one. It is said to be a very rare visitor 

 on migration to Heligoland is extremely seldom met with anywhere 

 in the furtherest west of Europe, and is really nothing more than a 

 casual wanderer in Central Europe, getting more and more common 

 to the East. Its stronghold is Siberia, European and Russian — 

 more particularly to the South, and Northern China. Seebohm 

 remarks : " Bewick's swan is a winter visitor to the Japanese Islands. 

 It was first included in the Japanese list on the authority of a 

 specimen in the Tokio Educational Museum (Blakiston and Pryer, Ibis, 

 1878, p. 212)." 



There is an example in the Pryer collection from Tokio Bay. 



Four birds were obtained by Mr. C. C. Ricketts at Foochow. These 

 were shot by one of his collectors in a bay on the coast south of Sharp 

 Peak, and were killed in January.
