well they look like poo from some creature but not sure what they could be. possibly worm casts but not sure why they'd be white. Some snails leave a similar looking trail.

not frog or toad though.

I'm baffled by it. There's such a lot that I was hoping for an amphibian, but never seen this before.

Looks like a few earthworms that got in over their head...5 days post mortem

Haha Loosetrife. I think you’re joking? They appeared overnight. My son thinks it’s probably bird poo.

Never seen any bird poo that shape. Very strange!

Poop-a-doodle-doo

Thankyou all. I've never seen bird poo like that either and not convinced. Poop-a-doodle-do indeed!

I was going to suggest asking the Devon Wildlife Trust but they appear to be closed at present - but there may be some staff there even if they are closed to the public. Alternatively try the Cornwall Wildlife Trust. A bit of a shot in the dark but you never know our luck- they are bound to have somebody there who will know.

Stera, I never thought of that and it's a great idea. Thank you and I'll let you know if I ever get an answer.

Yes please do!
