Can a canary and finch be in the same cage?

It is not advisable to keep a canary and a finch in the same cage. Canaries and finches have different space requirements and temperaments, and they may not get along well if kept together. Canaries are also more susceptible to certain diseases that can be transmitted to finches, such as avian pox and scaly face mites. For the safety and well-being of both birds, it is best to keep them in separate cages.
