BIRDS. 
A few remain during winter at the Little Ferry. Very 
common on Eabbit Island or Eilean-nan-Ghael, Kyle of 
Tongue. Eare, or quite absent in the west, so far as we 
can learn, although several suitable places occur, such as 
the sandy slope of Handa and the neighbourhood of Loch 
Sandwood. 
Has appeared of late years in the Kyle of Durness, and 
was seen there both in summer of 1883 and 1884 by Ben. 
N. Peach of the Geological Survey, and since then had 
increased to five or six pairs by 1885. 
Only recognised as an occasional visitant to Caithness 
(0. MSS., 1868). 
One adult male shot at Keiss Castle by D. Eoss, game- 
keeper, was preserved by Mr. L. Dunbar, and is now at 
Welbeck Abbey (Dunbar), and a second specimen is also 
in the same collection. 
218. Tadorna casarca (i.). Ruddy Sheldrake. 
[Included in Dr. Sinclair's collection. Seen by Wilson in 
Dr. Sinclair's cabinet with the rest of the collection 
" obtained by him exclusively in the county of Caithness " 
{Voyage, vol. ii. pp. 178-180).] 
219. Anas boschas, Z. Wild-Duck. 
Common, and resident, the only one of the true ducks that 
is commonly to be met with inland during the winter. 
Common in the west, and general in summer, often breed- 
ing up the hillsides and far away from water. 
Caithness name — " Stock- Buck." A very abundant and 
resident species, living chiefly inland, and only visiting 
the coast in the winter, during heavy snow-storms, and 
when they are frozen out elsewhere (0. MSS., 1868).
