They can be, but when female finches want to mate (male
present or not), they can become agressive and territorial-
and can nest in the food dish, keeping any other birds from
eating, let it be with other finches or other birds in
general. I would suggest not to allow different species live
in the cage. As with any other time, there can be bloody and
life-threatening fights between the different species. Toes
are at risk no matter how well they are said to co-exist,
even with same-species caged together.
