Swans and White tail deer
We just bought a pair of Royal Mute Swans for the pond. They are so graceful to watch. Another benefit is that they are territorial and will keep whole flocks of Canadian Geese from landing. The geese are pretty too but the make a lot of noise (and dirt). The swans are perfect residents.
We also have been having white tailed deer coming to drink in the pond in front of the house almost every day. They are not even afraid of people walking in and out of the inn! If you like nature, there is a mile long walk on a paved road that leads through a canopy of trees. You can walk listening to the birds sing and you can hear the water running through the brook.
