Swan Feeding

This mornings windy walk to the fishy ponds and the River Dane. Bbbrrrr! A bit nippy but nice to get out and stretch our legs. Saw a man with a bucket and trowel. We thought he was feeding the swans but he was very wary of the swans as they waddled towards us looking menacing but all they wanted was Hazel's frozen peas. Luckily she used them as a decoy and the man with the bucket ran passed and vanished into a hedge. What would he have been collecting I wonder? Mushrooms?
