Mike Toivonen found a rather odd find in his garden in Vällingby.
A couple of magpies had gathered outside the window prompting Mike to go outside to check.
– The eyes saw it but the brain did not want to accept what it was, says Mike Toivonen.
How it ended up in his garden is unclear.
– I suspect that a large bird may have pecked it and flown it here, says Toivonen.
