What is his name

Saturday we had a great speaker in the morning followed by a workshop and then in the afternoon a field trip to a place called Staglands . It was literally miles up a very steep winding road to a park like place of animals and birds etc. Totally fascinating. We were all intrigued with this little duck which none of us had seen before. Quite a bossy little one and was putting the mallards in their place. Does any one know what his breed is.
It was a fantastic place to visit. At night we had the convention dinner which was excellent and their entertainment was three guys doing what is called theatre sports. It was so funny we all roared with laughter.
