the whopoping crane is not a part of the food chain. Nothing would happen. 100 birds is not a pencil point in the data. We spend millions on this bird and it's lose would NOT be noticed by anyone. I'll bet not one person on this form has even seen one, can tell us what is food chain function is. A link to a post or wikpedia won't cut it either, I want the exact species that is in the chain both up and down and what the exact effect would be.
PS I've been to the AP and know all about them (clue tell us what I meant here and prove you are a player on this subject)
