The Cygnus ma)isuetus, or Tame Swan, a native of eastern Europe and Asia, 
may be enumerated among our domesticated birds, though it be but half re- 
claimed. It is larger than the preceding, and is readily distinguished by a 
black callous knob at the upper base of the bill. This species has been long 
esteemed as highly ornamental on pieces of water in pleasure grounds.

birds are resident ; but, in other places, they retire during the breeding sea- 
son This species, as the only permanently resident one, and the ym,ng of 
which could be taken and tamed, was reclaimed, at an early period, and is the 
stock of our domestic geese. Lister, in describing this species, says, “ Ros- 
trum a capite ad mediam fere partem ni^um, deinde subpurpureum, ipso 
ejus apice nigro.” — “ Pedes subpurpurei sive carnei colons ; ungues fere al- 
bidi excepto medii digiti, qui ex majore parte nigricat.”
