It's official, our mud is world class. Close to half of Britain's convoluted coastline lies within estaurine habitat, which provides crucial refuelling stations throughout winter to an internationally important array of waders from across the northern hemisphere.
Estuarine birds’ lives are totally dictated by the state of the tide, so the precise timing of your visit is everything. At low tide, the expanse of mud can be so vast that the birds will simply spread out across the ‘bird table’, giving the misleading appearance that the estuary is devoid of life.
Likewise at high tide, when the feeding ‘real estate’ becomes severely depleted, many waders will simply roost elsewhere until the waters recede.
The best time to get yourself in prime position for a ‘winter wader fix’ is on a rising tide, when the ever diminishing amount of mud will result in the birds being effectively delivered to your door.
