THE ROLLER CANARY 39 
Schnetter is a sharp bell, degenerating further into a 
rattle. Then there is soft Schnetter, which the novice 
mistakes for soft Aufzug, but which the expert knows 
is Schnetter pure and simple. 
Zitzit is a bad habit which, perchance, the bird may 
lose : nevertheless, he must be banished from the school. 
If he is inclined to let it drop he will have to do so in 
the company of the other banished ones. 
SEPARATE THE BAD FROM THE GOOD 
Birds that have the faults above referred to must be 
separated from the good songsters as early as possible, 
and placed in another room out of earshot; the chances 
that such birds may become decent songsters are very 
meagre, further, it is waste of time and effort to place 
them under a tutor. Let them sing their good and bad 
tours together to their hearts’ content, and take the first 
opportunity to dispose of them. 
One is often advised to darken these birds deeply, 
so as to suppress or stifle the fault, but this will not 
answer any good purpose, for the breeder who adopts 
the plan is thereby induced to keep the faulty birds in 
the same room as the others, thinking that by this means 
the faults will be less audible. One must bear in mind, 
however, that the birds cannot be kept in the dark during 
the whole day; they must, at least for one hour every day 
have light and freedom, even if it only be at feeding 
times, for then they should have quite an hour of broad 
daylight accorded to them, so that they may satisfy their 
needs in a proper manner.
