The drake on the left seems to be trying to convince Mrs Mallard to come away with him while the one on the left doesn't seem to be trying so hard. You can tell it's spring as all the ducks seem to be pairing up but this female doesn't seem to be able to make up her mind.
great title Rosie yes it looks like a conversation is going on it looks like the Duck that you have caught with his beak open is saying to the female Duck Ignore him he may go away my love
