When conflicts arise among endangered species:

[Michael Gochfeld]

The Bluebird x Butterfly dilemma is only one example. The introduction 
of Peregrine Falcons into New Jersey salt marshes has been highly 
successful.  Their favored prey: Least Terns (endangered) from the 
nearby colony.  Did the Peregrine people deliberately select a hacking 
site near this guarunteed food supply?
	Are Peregrines more "valuable" than Least Terns?  Bluebirds than 
butterflies?
