They have been long domesticated in Europe, birf are natives of South 
America, where they are called Aperea, and are of a reddish-grey colour. 
In confinement they are very prolific, and vary much in their markings. 
—-Two pairs of these were presented by Thomas Cator, Esq. 
Next is the Wolf’s Den (34). 
THE WOLF. (A Male and Female.) 
Canis Lupus, Linn. Le Loup, Buff. 
The Female is a native of France, and was presented by Peter 
Ingouville, Esq. The other is from Russia, and was presented from the 
Collection of the late Marchioness of Londonderry. The Female has 
several times produced puppies. Wolves inhabit various parts of the 
Continent of Europe. They are also found in the Northern parts of Asia, 
and in the cold parts of North America. They were once wild in Great 
Britain, but have been long extirpated. The last heard of in Scotland 
was in 1680. One was killed in Ireland so late as 1710. They prey on 
living quadrupeds, which they pursue by scent, but if hard pressed will 
feed on carrion. 
Returning from this place and passing the Eagle Aviary, the 
next object is the Pond for Swans (35), and the larger species 
of the Linnaean genus Anas, where the following birds may be 
observed. 
MUTE or TAME SWANS. 
Cygnus Olor, - — . Anas Olor, Gmel. Anas Cygnus mansuetus, 
Linn. Le Cygne, Buff. Mute Swan, Lath. 
The domesticated Swans are well known in this country. They are 
in a state of half- wildness on our large rivers, and on an estuary at Ab- 
botsbury in Dorsetshire ; and are said to be quite wild in parts of Russia 
and Siberia. 
The tame Swans which belong to this quarter have been removed to 
the Lake in the Regent’s Park, to prevent the collection of birds kept 
here being too numerous for the space allotted to them. 
WILD or WHISTLING SWANS. 
Cygnus ferus, Briss. Anas Cygnus, Linn . Le Cygne sauvage, Buff. Le 
Cygne a bee jaune ou sauvage, Temm. 
Found wild occasionally in Great Britain, and other temperate dis- 
tricts of all parts of the world, but abundantly in the Arctic regions, 
where they chiefly breed. Are sometimes called the Elk or Hooper Swan. 
They feed on aquatic plants and insects. — These birds were reared in the 
Menagerie of the Earl of Egremont, at Petworth in Sussex, by whom 
they were presented to the Society. The species differs in internal for- 
mation from the tame Swan, and is entirely distinct from it. The ex- 
ternal differences are chiefly in the bills, the base of which in the wild 
Swan is yellow, and in the tame Swan black. These birds also carry
