Big holes in my garden lawn...WTF are they?

[StephenStephen]

Crows and magpies dig holes like that.

Yes - I was thinking possibly a bird of some kind

Having looked at those holes again, if they have interconnecting tunnels it would be mice or voles.

Where I live we get short-tailed voles that make holes like that, the cats loved chasing them, occasionally bringing them in.

Has someone who is rather fat been sat on a big legged chair in the garden?

 

[bernardgreen]

Maybe Long John Silver has been there

 

[conny]

Definitely voles.
No idea how to get shut of them though.
