102 WAITE?: VERTEBRATES OF THE WESTERN AINSTY. 
SS olor (Gmel.). Mute Swan. A domesticated species 
which occasionally straggles into the district. 
ees immutabilis Yarr. Polish Swan. An example of this 
bird (perhaps to be regarded merely as a variety of C. o/or, cf. 
Proc. Zool. Soc., 1876, p. 466) was shot by Mr. John Harrison 
out of a flock of two or three at Wilstrop during late autumn, 
1860, 
Cygnus musicus Bechst. Whooper Swan. An occasional 
winter visitant. Small flocks of Swans sometimes pass over the 
district in winter, but usually at such an elevation that it is im- 
possible to distinguish the species. Nine Whoopers were 
seen on the Nidd at Wilstrop for nearly a week, about Christmas 
in 1859, during a very severe snow-storm, and of these five were 
shot. They were, I am told, all served up for ‘ Christmas 
dinner.’ 
Tadorna cornuta (Gmel.). Sheldrake. An occasional stragglet, 
generally during the floods. A male was shot at Wilstrop out of 
a flock of five, by Mr. J. Harrison, in Oct. 1881. This bird 
passed into the possession of Mr. J. Backhouse, of Harrogate. 
Anas boschas Linn. Mallard. Common Wild Duck. 
Resident and fairly common, much more so in_ winter; 
occasionally breeds in the district ; has done so at Wetherby. 
Dafila acuta (Linn.). Pintail. Very rarely seen, and only in 
winter. Mr. John Harrison shot two on the Nidd at Wilstrop, 
in the winter of 1881-2, The Rev. J. W. Chaloner has seen 
several of these birds at Newton Kyme, one of which fell to his 
gun in 6. 
sol igang crecca (Linn.). Teal. Common on the Wharfe, 
ut so on the Nidd; generally seen in winter, and 
Peaseoall in summer, but I have no record of it having bred 
in the district. 
Mareca Lipaieak (Linn.). Wigeon. A regular winter visitant 
and fairly common on both the Wharfe and the Nidd ; some 
seasons it is much more numerous than others. 
Fuligula ferina (Linn.). Pochard. Locally known as Red 
Not uncommon in winter; appears in larger numbers 
when the land is flooded. 
Fuligula cristata (Leach). Tufted Duck. A winter visitant; 
somewhat irregular and never common ; has occurred on both 
the Nidd and the Wharfe, and several examples have been shot 
by Rev. J. W. Chaloner on the latter river, at Newton Kyme.
