Robins seem to be guarding our yard, and chasing away any common grackles that land there. Sometimes we find a dead common grackle. We never find a dead robin. The dead common grackles show no obvious signs of violence, other than being dead.
I'm just curious to know how likely it is that the robins might be killing the common grackles.
Or do common grackles ever get killed by bumblebees? If they invade the bumblebees' nest, and get dozens of stings, can that kill them? Would they fly away, and then die from the stings, and fall in the yard?
We have an unknown number of bumblebees, and it's the only kind of flying stinging insect we ever see here. We've never been stung, but they do sometimes seem to try to scare us away, by flying towards us at high speed, as if to attack.
