The Exe estuary at low tide has huge expanses of exposed soft mud, pullulating with invertebrates. That, together with its temperate climate, make it an important site for large flocks of overwintering birds: geese, ducks, waders and more.
When the water’s out, there’s usually a handful of turnstones close to the Goat Walk at Topsham. They wander, more or less as a group, from one clump of seaweed to another, probing the ground searching for things to eat.
