Yes, they can I got finches,canarys,cockatiels and budgies. But if you want the finches to breed get the budgies out as budgies steal there nestboxes if in breeding mode. If you want breeding sucess I would separate them Improved Answer I absolutely would not recommend keeping finches and budgies together.
You should keep birds of the same species or at least family together. Finches are much smaller than budgies, and cannot defend themselves should the budgie decide to attack. Budgies can take off a finch's foot or beak.
The same goes for keeping budgies with birds bigger then them. Budgies can suffer a similar fate, with missing toes and beaks, from a bird only a little bigger than them, such as a cockatiel. It is not a good idea.
I have experience both personally and professionally with birds SHE IS RIGHT ABOUT PROTECTING THEMSELVES. BUT I HAVE 4 DIFFRENT BREEDS IN A COMUNITY CAGE . IF THEY ARE RAISED THAT WAY THEN IT IS OK.
IF NOT THEN KEEP THEM APART. THEY REALLY ARE BULLIES I agree as well. If you want a community time aviary, you need to keep the same time of species or family together like she said .
Just an example would be finches , canary , and a diamond dove. If you have questions about the species family look it up or just look at the beaks! They all have similar beaks.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
