Eurasian teal
The area is important for its extensive reed beds and for nationally important numbers of wintering wildfowl and wading birds. The inner Forth hosts populations of common shelduck, red knot, common redshank, great crested grebe, Eurasian teal and common goldeneye. A marsh harrier, of which only a handful of pairs nest in Scotland, was seen on the island in September 2006.
