this sticky has more info on sex-link recessive mutations, which pearl is. Sometimes, you will find a pearl male that has kept one or two pearls (like literally on his entire body, one or two yellow spots.) Males will also sometimes have what's called ghost pearling, which is a white shading to the feathers that indicates the bird is a visual pearl. The photo attached is of my pearl male split pied, Fuzzy. Because he was split to pied, Fuzzy didn't full lose all his pearls until he was well over two years old. In fact, he kept the yellow tail feathers for several molts. If you look near his wing, you will see a couple pearls he kept and some of the white shading I was talking about.
