BEWICK'S SWAN— COMMON SHELDRAKE. 219 
166. Cygmts bewicki. Bewick's Swan. 
An occasional winter visitor. It is by no means infre- 
quent in some winters, but as it was only recognised as a 
separate species about 1829, there are no early records of 
its occurrence. 
It is more rarely seen on inland waters even than the 
last species. 
In the Hart collection are specimens procured in 1861, 
and on October 19th, 1885. Wise^ says it has been killed 
on the Avon in the winter of 1855. 
There is also a specimen in the Earl of Malmcsbury's 
collection at Heron Court. 
At the end of the year 1880, an adult and an imma- 
ture bird remained on the lake at Laverstoke for about a 
week. 
It is easily distinguished by its much smaller size from 
any of the other swans that occur in the county. 
Genus — Tadorna. 
167. Tadorna cornuta. Common Sheldrake. 
Burrow-duck. Bargander. 
A scarce resident on the coasts of the mainland and 
the Isle of Wight. Visiting all parts of the coast in winter 
and occasionally wandering inland. 
Hawker has few references to this bird in his "Diary," and 
judging by his total bag of thirty-seven in fifty years, it 
was not much more common then than now.
