Magpies or squirrels trying to bury food. But I would go for foxes or even badgers is they can access your garden looking for worms this time of the year.

I'd check each hole to try to lever out any 'nut' that's been buried- the last thing you want in a lawn is lots of them germinating in there next spring! Its unfortunate its been so wet - they usually bury these things in the borders or in pots cos the lawn isn't soft/wet enough...

Squirrels have done same to mine burying acorns and they usually never come back for them. I'll have a forest of oak trees to clean up next spring.

Oh gosh! That's a pain...but also a tiny bit funny ;)

Thanks folks problem is I love watching the little devils 😄

The Squirrels in my garden have been a digging, I’ve got a Dahlia in a pot and it was digging & turfing the soil out of there, plus the lawn has lots of holes in it too, the Little Critters.
