As we have seen before, birds defend their nests and territory. Here, an osprey is chasing a bald eagle away above our house. The osprey has a nest on top of a cell phone tower close by and is willing to take on a much larger bird to defend it.
But, what comes around goes around. Here, an osprey (maybe the same one?) has gotten the attention of an annoyed crow. Can you see the osprey in the fir tree? After a couple of minutes of this, the osprey finally flew away.
