BRIEF: What is in avocado that kills parrots?
QUESTION:
                                                                          
We had a bird die years ago who ingested avocado.  The vet at the time said it  
was poisonous to parrots.  What is the ingredient in an avocado that would kill a  
parrot and not kill humans?                               
 
ANSWER:
                                                                            
Some avacados have a toxin that attacks the mammary gland (not on birds, of        
course...) and lungs, others are safe.  It is hard to tell them apart.  If I run   
across the avocado toxicant, I'll let you know...
