Parrots do not eat mushrooms in the wild because they cannot tell which ones are poisonous and which ones are not. They instinctively know that any mushroom they come across could be detrimental to their health, so they simply avoid them all. However, we humans know that certain mushrooms are not poisonous. So, since these mushrooms are healthy for humans, can parrots eat them too? The short answer is that there is no consensus on whether parrots can eat mushrooms.
The Data Is Limited
Unfortunately, there is no real scientific data available that tells us whether mushrooms should be consumed by parrots. The lack of studies makes it difficult for experts to provide any insight or guidance to parrot caretakers. Therefore, we must rely on experienced parrot owners and internet research to try to figure out whether parrots can eat mushrooms of any kind. With limited data to work from, finding an answer is not an easy task because different sources come to different conclusions.
There Is No Consensus
One resource may say that parrots should never eat any kind of mushroom, while another resource says that button mushrooms are safe for these birds. Some resources indicate that mushrooms are safe for parrots only if they have been cooked. Other resources suggest that only the stems are dangerous for parrots.
So, there is no single consensus on this topic. One thing we know for sure is that no parrot has ever been reported to have died after eating a mushroom. Many parrot owners say that their parrots have no problem eating basic mushrooms found at the store, such as buttons, portobellos, and creminis. The bottom line is that you must decide for yourself whether giving mushrooms to your parrot is a good idea.
