Normally by early December, I would expect that the local Common Frogs were all hibernating & only occasionally appearing during a short mild snap. Apart from a few days in late Nov, when there was a cold snap, it has been a mild Autumn. As a result, I've see a Common Frog in my larger pond on a few occasions recently. Today, I saw it out looking for some food. Although it is hard to see where it will put that food, as it was remarkably stout.
