The first thing that happened is that we had a wolf show up on shore just after dark the first night. We have spotted wolves a couple times in Alaska, but it is pretty rare, and even though we didn't see this one, there is nothing quite like listening to a wolf howl in the darkness.
After a few minutes the eagle flew off to a tree on the shore. The heron waited several more minutes and then took off flying in the other direction. Sure enough the eagle was waiting, and went streaking across the anchorage to dive at the heron again. This happened two more times, each time the eagle would go back to shore, the heron would take off flying, and the eagle would give chase until the heron ditched in the water again. Finally the heron took off in the other direction across the channel and the eagle gave up.
Neither Nicole nor I could figure out what may have started the whole feud. It seemed like the eagle could have picked the heron out of the water easily enough if it wanted to, they do it to salmon all the time, but it would always give up as soon as the heron landed. What ever the case, it was an unusual and interesting spectacle to watch.
