Well, kittylester! I have spent a riveting time looking at pictures of various types of bird poo - it's quite educational ????????? ?
I remember seeing lawns covered in poo of Canada geese as they resided on a lake near where my DB and SIL lived - rather green and perhaps not so well-formed as the one in your picture. But perhaps that's due to diet.
Baggytrazzas, I know - it was a joke (very feeble one obvs!)
J52, I found that picture too - that is the best match I could find.
calistemon, our very small garden already has a hedgehogs, squirrels, a kestrel, a visiting fox and a pooing goose - not sure we can cope with a bear too.
