Case Reports Case Reports at The BIRD Clinic Welcome to The BIRD Clinic's case report library. Our goal in this section is to profile interesting cases at the clinic and some of today's technology used to resolve the medical condition. I hope this section is informative and that it may even one day help to cure YOUR pet if it develops one of these problems.   May 2003 Eggbound with Egg Yolk Peritonitis in a Cocktiel.
