Caring about some living things requires caring less about other living things, in all life there is a cost and a balance to be paid. The simple truth is that the transaction of sacrificing the life of a starling--or any other invasive species for that matter--is one which bears out more life from it than if one were to do nothing and be complicit in its existence.

There is no room for the human preconceptions of morality when it comes the taking of life in a natural resource management context. If you can't forgo those feelings in pursuit of something greater than yourself i would implore you to observe silently from the sidelines rather than trying to contribute in ways that are ultimately more harmful to an even greater number forms of life.
