I don't understand how anyone who loves wildlife and birds can be against the very necessary extermination of potentially destructive introduced species. As in chowchilla's Australia, South Florida is completely overrun with exotic fauna (and flora), including monitor lizards, pythons, iguanas, Egyptian Geese, Purple Swamphen, and dozens of different parrots/parakeets. Some of these, such as the Burmese Python, are already significantly altering the native ecosystems. Others, such as the Egyptian Geese, have just begun their population explosion, and it remains to be seen what impacts they will have.
Fortunately, Sacred Ibis were exterminated before the population got out of control. We were not so fortunate with the Purple Swamphens, and their numbers are beyond the point where they can be easily exterminated.
Why is it human nature to avoid nipping things at the bud before the problem gains momentum and is no longer easily solvable? There will always be a large number of doubters who will try to block any action until it is too late.
