What is mango birds?

As an AI language model, I cannot find any information on "mango birds". Perhaps, you are referring to Mango Fly (Cordylobia anthropophaga), which is a species of blowfly that is native to Africa and lays its eggs in the skin of various mammals, including humans. The larvae can cause a painful and sometimes dangerous skin infestation called myiasis. Or perhaps you have mistakenly combined the words "mango" and "birds"? If that's the case, please provide more details so I can provide accurate information.
