New Pond Making our way back to the castle through the Cwm Philip Valley the valley opens out to the deer lawns and New Pond. During the winter many waterfowl come to the pond. Pochard and gadwall ducks seen commonly Resident all year are coots and moorhens. In the summer a large flock of canada geese nest on the island. For several years an unusual bar-headed goose has stayed with them. The same birds return each year. On warm summer days swifts, swallows and martins can be seen catching insects over the pond surface.
