• In smaller numbers are mallards, shelducks, grey herons, cormorants, greylag geese, Canada geese, mute swans and the occasional family of goosanders.

• It has internationally important overwintering redshanks and nationally important numbers of dark-bellied brent geese, shelducks and black-tailed godwits.

• The original formula has been entirely lost, although Pliny reports that Mithridates' various antidotes usually included the blood of Pontic ducks (possibly ruddy shelducks), which fed on poisonous plants like hellebore and hemlock and thus provided a kind of serum against them.

• Waterfowl winter on the shores of the sea and estuary, while the coastline supports a variety of breeding species such as whitethroats (Sylvia communis) and magpies (Pica pica) in the scrub; skylarks (Alaunda arvensis) and meadow pipits (Anthus pratensis) in the grassland; and wheatears (Oenanthe oenanthe) and shelducks (Tadorna tadorna) in holes or burrows.
