Rat-kill to live-bird ratio?

#1

To friends and colleagues, I really dislike divulging how may rats (i.e. animals lives) I am responsible for terminating. I hate the task, but do this because I have witnessed the massive difference in bird life in a mere 24 months… a worthy trade-off.

Does anyone have any thoughts or figures on… for every rat I kill, “x” birds are saved? Even if it was 1-1, I would be content… but I can’t help believing it’s higher than that.
