The Loch of Swannay is the most northerly loch on the mainland of Orkney and lies within the parish of Birsay in the north west of the island. It is an elliptically shaped, freshwater loch and is close to the lochs of Hundland and Boardhouse. The grassland at the shore of the loch is the main feeding area for a wintering flock of rare Greenland white-fronted geese and the rare flat-stalked pondweed is found in the waters. Many varieties of birds use and nest in the loch including mute swans, skylarks, meadow pipits, twites, gulls and sedge warblers.[3] It is also popular for trout fishing.[4]
