Glad you think so. Clearly I don't understand your point.
Your argument:
1. Lady A Pheasant is as likely a wild bird as a Falcated Duck because the chances of escape are basically the same. I disagree.
2. Falcated Ducks are almost certainly escapes because they can occur with Mallards. And Mallards are like feral Barnacle Geese. I disagree.
3. Mallards couldn't be a carrier species as they don't migrate in the same way. I disagree (nor do any ducks migrate east Asia to western Europe, yet we know east Asian ducks have reached western Europe).
4. The Lady A is a hunky dory class A wild bird. I disagree
