On Patrol - With Insurance

The Nairn Swans have adopted a two strand approach to safeguarding their territory. They have deposited the cygnets in the river around the island, and placed themselves in the harbour to keep any intruders out ! They have regular patrols down to the estuary on the lookout for the intruder cob, whilst the cygnets keep out of their way up river. This is a pretty good strategy and insurance to show that the territory is occupied !
