What's the difference between a wenbird and a nanny bird?

Nanny birds are ten sister birds, also known as white-waisted birds, fortune-telling birds and cereal birds. They belong to the golden-bellied finch family and are mostly exotic species. Because it is easy to raise, it gradually multiplied into various forms and then made various improvements, and now there are species. Ten sisters have strong nesting ability and are the best at brooding among all birds, so they are good "nanny birds". See Baidu for details.
