Updated August 20th, 2016. Peanuts are a popular food amongst bird enthusiasts for feeding birds of different kinds.
This is because birds do love them and they are real treat for them.
There are different kinds of bird peanuts that you can purchase and they are a good source of protein and fat for them.
They can be fed to both birds in the wild and those that are held as pets. (source)
So can hamsters eat bird peanuts?
If they stumble upon them and nibble one or two they will be fine.
But they aren’t a food that should be fed purposely to them.
They are very high in fat and so are not very good for them.
