Can a canary and a finch be in the same cage?

Yes! Certainly you can. First I was afraid to put a pair of finches in a cage of 6 lovebirds who had their 5 babies in nest box.But when I put finches inside the cage, the two species never cared about each other.I had heard that lovebirds are very aggressive during their breeding time but they never came close to finches. Make sure that cage is big enough, mine is 3 by 3.Happy mingling!. Two species in one cage look very attractive.
