Then I'd let them eat whatever it was they were hunting. Not my place to step in and decide, well not my pets, but a wild animal yeah. It's the way it's supposed to be. The food chain is set up to provide for the higher ups so I'd let them have the wren or whatever it was. It's all a balance. Predators are supposed to and have to hunt the prey, or the prey animals become too abundant, therefore actually starving themselves and us out by eating everything when the land can't support the numbers.
As for the endangered animal eating an endangered plant? Well I wouldn't know if either was endangered, so I'd just keep on walking by LOL.
