Pec slapping at Kaloli Point

[TomK]

Thanks, AKpilot. I was reading about humpback behaviour a few years back and remember the "lobtailing" thing, but it's my impression they use that when feeding (to scare the fish into a particular area) which of course they don't do here - feed that is. I suspect the noise we could hear wasn't breaching (which they do do here) because it just didn't sound right, it was more of a sharp slapping noise, but lots of it and much more than I've heard before.

I wonder if the thunder and lightning had anything to do with their behaviour?
