The ducks have had an extra pond on there during the recent deluges! There's at least one pole beside the house so it looks as though the plan is for the orangs to be able to cross the moat by ropes, netting or whatever.
You may have noticed that what was left of the old trees has been cut down.
The poles were being connected with lots of straps this morning. At the same time, the tall trees on the large island, seen in the background in this photo, were being cut back, or maybe cut down - I wasn't there long enough to see the outcome.
