Loch Fleet (ON fljotr, flood) is a National Nature Reserve and tidal estuary of the River Fleet covering over 1,000 hectares and supporting a wide range of wildlife.  There are good vantage points around the loch to watch Common Seals haul out onto the sandbanks.  Otters are present and Ospreys breed here and are regularly seen fishing.  Buzzards and Sparrowhawks are common, whilst Curlew, Oystercatchers, Redshank, Shelduck, Widgeon and Teal are present all of the year.  In autumn and winter Bar-tailed Godwits, Dunlin, Turnstones, Greylag and Pink-footed Geese can be seen in prolific numbers. At the Mound sluice gates allow Salmon and Sea trout to pass by on the ebb tide.
