True!! Die hard predators!!! If they are away from our house, I don't bother them. I leave them alone unless they become a threat. A nest on a home can be dangerous. Being attacked can mean a hospital visit or death. They are very sharp, quick to defend if here is a lot of traffic around their nest. I just let them have our crabapple. I don't see any reason to bother them. They are sheltered within the canopy . What's the saying...let sleeping dogs lye.
