Pond Snails

[LinL]

Any ideas what would be eating our ramshorn pond snails ? I found about 6 empty shells on the grass next to the pond. I have Googled it, but the only answer I found suggested a racoon...but living in Herts, I don't think so !!
Thanks.

Hedgehog.. if they are up near the waterline easy for a hedgy to fish them out A thrush might also get them the same way

Thanks rowanwitch, I haven't seen hedgehogs in the garden, but it's a thought. The snails are usually pretty deep so don't think it could be thrushes.

If it were thrushes, the shells would be broken open. Ramshorns have lungs, and have to come up occasionally for air - this could be when they're vulnerable. Predation - take your pick...

Could it be a heron?

Thanks for that link heathfield, very interesting. Being pond snails I guess frogs and toads are highly likely culprits...or the heron. Just seen one flying over again !!
I would love to see how the heron gets the snails out of their shells though.
