feature in the Chinese bird, distinguishing it from the Japanese 

 representative. On the other hand, the late Consul Swinhoe appears 

 to have had no doubt that the grey plumage was that of the young

 neger (I. c.) in 1887, but even he was unable to arrive at a definite 

 conclusion on the subject ; and so far I myself have not been able to 

 decide the question, but I incline to the belief that the grey birds 

 are the young, and that they retain this phase of plumage for some 

 time before assuming the white plumage of the old bird.
