I just recently purchased a Pied Cockatiel and was wondering how to sex him/her. I already own a gray cockatiel which is a male since the facial feathers are bright yellow as opposed to gray. My question is, "What plummage differences exist between juvenilles and adults among Pied Cockatiels?" This bird is primarily yellow with wings like a gray. I do not read rec.birds regularly, so please respond by e-mail if possible. TIA William J. Murphy murphy@newton.physics.purdue.edu
