Earl of Sodak, Jamie, whichever,
Nice pictures. I don't have a stomach pump and so the little that I do inspect stomach contents, I am inspecting a fish I just cleaned. And I usually end up with more mess in my hand than clearly identifiable meals -although there is usually one or two things I can pick out, probably the more recent meals.
Anyway, very interesting pictures. If you are willing, I would encourage you to post more: different streams, different times of year, different times of day, and label them. That would make a great reference.
Thanks again for the post.
