Vast flocks of birds return to Somerset and a rare grebe turns an ordinary walk into something special

After weeks of heavy rain, Cheddar reservoir in Somerset is finally full again – of water, and of birds. Thousands of coots, hundreds of gulls and ducks, and dozens of great crested grebes crowd the surface, some already moulting into their smart breeding plumage, crests and all.

They feed almost constantly, building up energy reserves for the breeding season. Among the throng are some less familiar visitors: a flock of scaup, the males bulkier than the nearby tufted ducks, with pale grey backs that catch the light. Flocks of goosanders dive frequently for food, the colourful males looking like a cormorant in extravagant drag.
