Jordan Lake: Usually when ospreys have a disagreement, it is worked out through lots of chatter, high pitched squeals and a couple of bluff dives. There was no bluffing involved in this dispute between two adult female ospreys. None. I think the aggressor was on her own turf and decided she was going to make sure the other female left. I have never seen one osprey deliberately strike another osprey but that is what happened. Yikes! Neither seemed the worse for the encounter as both flew out over the lake, still screaming.
