Eurasian teal
Tees and Hartlepool Foreshore and Wetlands SSSI is an important wintering site for waders and wildfowl and supports nationally important populations of purple sandpiper, sanderling and Northern shoveler. Surveys have demonstrated that numbersof other birds, making up significant portions of the Tees estuary's populations, frequently use parts of the SSI for foraging and roosting. These include sanderling, red knot, purple sandpiper and ruddy turnstone on the north Hartlepool shore and Hartlepool Headland; while common redshank, Eurasian curlew, Eurasian teal and common shelduck use Greenabella Marsh; northern shoveler, Eurasian teal, Eurasian wigeon, gadwall, Northern lapwing and European golden plover use both Saltholme Pool and Dormans Pools; and common redshank and common shelduck on the North Tees mudflats.
