X. The Tufted Duck in Scotland: its Increase and Distribu- 
tion. By J. A. Harviz-Browy, Esq., F.RS.E., F.Z.S. 
(Read 18th December 1895.) 
The facts upon which the following conclusions are based 
have been communicated to the Annals of Scottish Natural 
History, and appear in the January (1896) number of that 
magazine. 
The present paper treats somewhat more fully of the Con- 
tinental distribution, and subsequent dispersal in England 
and Ireland, than was attempted in the portion exclusively 
confined to Scotland. 
Since the Annals paper was printed off, I have received 
a letter from Mr J. G. Millais, in which a very early occu- 
pancy of Loch Leven is hinted at—presumably as a winter 
visitor—and which I consider of sufficient interest to quote 
here. Mr Millais writes as follows :— 
“When I first began going to Loch Leven, in 1879, 
Sir Graham Graham-Montgomery’s boatman was John 
Maunderston, a most observant and charming old man, and 
devoted to birds. He died about 1884, if I remember 
rightly. All his life he had studied birds, and had lived 
beside Loch Leven. I perfectly well recollect talking to 
him on the subject, and his saying that the tufted ducks 
had been on Loch Leven ever since he was a boy (he died 
at about seventy years of age), and that he had often heard 
his father speak of the same ‘black and white dukers’ 
living and nesting there. Personally, I have little doubt; 
that Loch Leven has been favoured with their presence for 
a very considerable period—much longer, probably, than 
any place in Scotland, the superb feeding in the islands, 
and comparatively warm climate, are all such as would 
attract them. I have no written authority for saying that 
the birds were there at the beginning of the present century, 
but I believe what Maunderston told me about his father 
frequently referring to their presence on the lake.” 
Regarding these statements, I have no remarks to make 
at present, but I was in communication with Sir Graham
