This is about as definitive a demonstration of an ecological interaction (predation in this case) as one can get. Later in the year we are going to introduce a way that you can record such 2-species interactions. Look out for it!

I will look forward to that

I will look forward to that new recording method Jonathon. It will be useful and also very interesting to see the interactions people submit.

Thanks Ian, As you will

Thanks Ian,
As you will appreciate, studying fish closely both on the outside and within (if they are kept for the table) can reveal many very interesting stories which could easily be overlooked. Parasites outside and within, and food items within are sometimes astonishing. I've seen a few marine organisms in the stomachs of sea fish which I'd never have seen in my life if I hadnt had a look, best example that comes to mind was a coley full of juvenile 'little cuttlefish' Sepiola atlantica.

The fish themselves are always interesting but sometimes the critters within are even more so in my opinion. You never know what will be in there. Cheers.

That ecological interaction...

ended up as our sustenance that evening and remember Cáthal how the Teal came in to roost on the loch. The next morning when we got up a lot of Teal feathers were strewn not nine feet from our tent, where we deduced the Peregrine must have hit and landed with him at dawn.Yet another fascinating ecological interaction. I think you or I have photos of that incident?

I'll have a look Peter, I

I'll have a look Peadar, I think your'e right but it might be difficult to take the ID to teal from the view of the feathers available. Yes the only evidence of duck predation that happened that morning happened virtually on top of the tent.
