CANARY BIRDS. 



smaller marks spreading, more or less regularly, over the 

 whole body. 



One-wings — whose right or left wing alone is coloured. 



Half-swallows — displaying, on one side only, the 

 swallow-marks of which we will treat further on. 



(b.) Plate (or Disk)-birds, which have a coloured mark on 

 the head only (the more regular that mark is, and the 

 more pure and full the colouring of the body, the higher is 

 the value of the bird). When this plate, or disc, is very 

 small, they are called small-warbler (original) (" Muckchen"). 

 Otherwise, they are divided into grey, green, brown and 

 black " plated " birds. 



(c.) Grey, green, brown, and black crested birds, with a 

 coloured crest or crown which, as well as the body, should 

 be of as even a colour as possible ; they, too, are highly 

 prized, and the more symmetrically marked they are, the 

 greater will be their value. 



(d.) Swallows. — Birds of a dark colour, or such which 

 are coloured only at the head and wings, being otherwise of 

 a pure, yellow tint, are called swallows ; we distinguish, 

 according to the colour, grey, green, black, and " dun " 

 swallows, and the more regular the marks, the dearer are 

 the birds ; the most prized are the "crowned " dun swallows, 

 whose heads are ornamented by a small curly crown ("Tolle") 

 and whose wings are of a reddish yellow, while the remainder 

 of the body must be a very pure, bright yellow. All 

 swallows may be either smooth-headed or crested — those 

 which have coloured wings, while the head and body are a 

 pure yellow, are called wing-swallows. 



Albinos — (or White). — We must further mention the 

 "Albinos," an unsightly error of nature, which fortunately 

 does not frequently occur; these birds are a pure white, 

 with red eyes. This variety (Albinismus) chiefly result, 

 among various animals, from unfavourable conditions of
