About the reserve

The reserve consists of two disused clay pits with associated reedbeds and adjoining scrub and pasture. The pits are particularly important for a wide range of birds, not only as a breeding site but also as a migration staging post.

There are 108 species of birds recorded on the reserve with over 20 species breeding, including reed and sedge warblers, water rail, garganey and, in the past, bittern. Snipe are regular visitors. Migrant waders include green and wood sandpipers, redshank, greenshank and ruff. Numbers of surface-feeding ducks, such as shoveler, teal and mallard, are at their greatest in late winter and early spring. Vagrants have included spoonbill, green-winged teal, Bewick's swan, little bittern, red-crested pochard and pectoral sandpiper.

A 9 hectare (23 acre) block of old pasture was added to the reserve in 1991. This is a good area for curlew, the numbers of which in winter are often in excess of 200, and for other waders, especially when the fields are flooded in winter. The reserve extends to part of the foreshore, from where both passage and wintering waders may be seen.

Management consists of grazing with cattle and Hebridean sheep, cutting of the wet grassland, annual hay-cutting of the species-rich grassland, and some scrub management.
