185. Cyenus Bewicki, Yarrell. Bewickh’s Swan. 
Searcely less common than the preceding, and arrives under the same 
conditions. 
186. Cyanus otor (Gmel.). Mute Swan. 
Eseapes, and also undoubtedly wild birds from the Continent, have 
been obtained on the coast districts in severe winters. In the very 
severe season of 1894-5 several were washed up dead on the Lincoln- 
shire coast. 
187. Cyenus mmmutTaBinis, Yarrell. Polish Swan. 
One was shot, and a flock seen of this doubtful species off Brid- 
lington Pier in 1844 by Mr. Arthur Strickland [‘ Hand. Yorks. Vert.,’ 
p. 54]. 
188. Taporna cornuta (8. G. Gmelin). Sheld-duck. 
Resident, and nests in limited numbers both inland and on the sea 
coast. Flocks, probably of foreign origin, of 200 to 300 are seen off the 
Lincolnshire coast in the winter. 
189, Taporna casarca (Linn.). Luddy Sheld-duck. 
September 1st, 1892, one, a female, in Mr. Haigh’s collection, was 
shot from a pond on Humberstone fitties. Considerable numbers 
appeared in this autumn in various parts of Great Britain and Ireland 
|‘ Zool.,’ 1892, p. 334]. One in the Lincoln Museum was shot on the 
Trent, October 20th, 1898, two others being seen at the same time. 
190. Anas Boscas, Linn. Mallard or Wild Duck. 
Common, resident and nesting generally throughout district, many 
being in a semi-domesticated state. This is one of the species which 
has very considerably increased in number. Thousands of foreign birds 
arrive in October and November, frequenting the coast, Humber waters 
and Lincolnshire Wash ; they are smaller than home-bred birds. 
191. ANAS STREPERA, Linn. Gadwall. 
A very rare winter visitor. Between the winters 1833-’34 and 1867-68 
thirteen only were taken in the Ashby decoy in North Lincolnshire. In 
May, 1882, a pair were shot on the river Hull [‘ Nat.,’ 1882, vol. vii., 
p. 185]. On January 31st, 1871, an adult male on the Driffield trout 
stream [‘ Zool.,’ 1871, p. 2525]. 
192. SparuLA cLyPEATA (Linn.). Shoveler. 
Resident and nesting, and in recent years has extended its breeding 
haunts in several directions, and has become more generally distributed. 
A regular autumn immigrant, but in no great numbers. 
198. Daria acuta (Linn.). Prntarl. 
Winter visitor and not uncommon, although irregular in appearance. 
Old males are scarce. I have met with it late in April and in the most 
perfect breeding plumage. 
194. Nrerrion crEcca (Linn.). Teal. 
Resident, nesting locally in some numbers. Large arrivals in the 
autumn from the Continent. I have seen teal off the coast as early as 
July 9th. The usual time of arrival is from middle of August through 
September. <A return migration in March. Are not nearly so common 
on inland waters in winter as formerly.
