Species vs. Species

...ause loggerhead shrikes on San Clemente Island are critically endangered, the foxes that prey on their nestlings should be controlled. Right? Wrong. The problem is that the foxes are also at-risk. A new analysis shows that instead of pitting the shrike against the fox, both species could have been protected wit...
