140 BRITISH BIRDS, THEIR EGGS AND NESTS. 
233, RED-BREASTED GOOSE—(duser rujicollis). 
A very rare species, and one of which but little is known as to 
history or habits. 
234. HGYPTIAN GOOSE—(Auser Eyyptiacus). 
Equally rare and more exceptional than the last; as the few 
that have occurred may have escaped from confinement. 
235. SPUR-WINGED GOOSE—(Auser Gambensis). 
Gambo Goose.—An accidental visitor indeed. 
236. CANADA GOOSE—(duser Canadensis). 
Cravat Goose.—Many of these remarkably fine birds are kept on 
ornamental waters in many different parts of the kingdom; and 
these have been known sometimes (aided by a storm, perhaps, 
or some unusual occurrence) to make their escape. Many of the 
supposed wild birds shot, or otherwise taken, have been accounted 
for on the supposition that they are such escaped birds. How- 
ever, it would seem most probable that considerable flights of 
really wild Cravat Geese do occasionally visit this country, and 
even that some pair or twoof them may occasionally stay‘ to 
breed. The eggs are six to nine in number, of very large size 
and white. 
937. HOOPER—(Cyguus ferus). 
Wild Swan, Whistling Swan, Elk.—Of sufficiently common oc- 
currence on the British coasts, and particularly in hard winters. 
Few birds vary much more in size and weight than do these. A 
young bird of the year may weigh only twelve or thirteen pounds ; 
the older and more full-grown specimens, twenty or twenty-one. 
They breed very far to the north. 
938. BEWICK’S SWAN—(Cyguus Bewickit). 
A smaller bird than the Hooper, and of very much rarer occur- 
rence. Still it is an ascertained species, and visits us frequently, 
not annually, in some numbers.
