CANARY BIRD, (_Fringilla canaria_, LINN.) _s._ A much admired singing bird. In length this beautiful species is about five inches and a half; the bill pale flesh-colour, passing into reddish white; eyes chestnut brown; the whole plumage of a rich, deep primrose colour, inclining to yellow; edge of the quills sometimes yellowish white; legs and feet the same colour as the bill. The female is distinguished from the male by the plumage being of a paler colour; the yellow round the bill, eye, and on the breast and edge of the wing, being also of a paler yellow; she is likewise rather larger and less slender in form towards the tail. There are said to be upwards of thirty varieties of the breeds of canaries, which can be easily distinguished; and the number is increasing every year. In London, we have societies for promoting the breeds, and a premium is awarded to the competitor who comes nearest to the model of perfection given out by the society the season prior to the competition.
