Spotting Sanderlings and Dunlins on Crimdon Beach

Whenever I am walking the wide, wind-scoured tideline of Crimdon Beach in the depths of winter, I am rarely alone.

Even on the quietest mornings, when the frost clings to the marram grass of the dunes and the North Sea looks like cold slate, the edge of the surf is absolutely alive with movement.

If you stop walking for a moment, quiet your mind, and watch the retreating waves, you will see them: tiny, hyperactive flocks of wading birds moving in perfect, frantic synchronization with the water.

These are Crimdon’s winter stars—Sanderlings and Dunlins.

To the untrained eye, they can easily look like an indistinguishable blur of gray and white feathers darting along the sandbars.

But once you know what to look for, their individual personalities, plumages, and distinct hunting styles become beautifully clear.

🦅 The Quick-Reference Field Guide

🏃‍♂️ The Sanderling: Crimdon’s Clockwork Sprinter

Sanderlings are the ultimate entertainers of the Durham coast. They don’t just walk; they sprint.

Their feeding strategy is entirely dependent on the rhythm of the waves.

As a wave crashes onto Crimdon Beach and rushes up the sand, the Sanderlings run backward just ahead of the foam, keeping their feet dry.

The exact millisecond the wave stalls and begins to slide back into the sea, the flock spins on a dime and chases the water down, frantically pecking at the wet sand to snatch up tiny isopods, amphipods, and marine worms exposed by the surf.

In winter, they are the palest waders on the beach. They look almost snowy white from a distance, sporting a clean white breast and an icy-gray back with a dark smudge at the bend of their wings.

If you happen to find a track of tiny footprints left behind on a quiet sandbar, look closely: because they lack a hind toe, their prints show only three forward-pointing needles.

This evolutionary tweak gives them incredible traction and speed, making them look exactly like tiny, wind-up clockwork toys running along the shore.

🪡 The Dunlin: The Patient, Down-Curved Prober

While Sanderlings are busy playing chicken with the waves, Dunlins take a much more measured, systematic approach to finding breakfast.

If you spot a small wader that looks a bit more hunched over, darker, and completely unbothered by chasing the surf line, you are looking at a Dunlin.

Dunlins are slightly smaller than Sanderlings, but their bills are noticeably longer and possess a highly distinctive, gentle downward curve at the absolute tip.

In winter, their plumage lacks the bright, clean whiteness of the Sanderling; instead, they wear a more muted, uniform grayish-brown coat with a subtly streaked, dusky chest.

Their feeding motion looks exactly like a busy sewing machine.

They tend to stick to the calmer, muddy edges where freshwater streams like Crimdon Dene cut across the sandbars.

Here, they stand or walk slowly, rapidly driving their long, sensitive bills deep into the soft mud to feel for hidden mud-shrimp and small worms.

🐾 The Birdwatcher’s Code: Ethics on the Sand

Malc & Pete’s Field Notes

Watching these birds change direction in mid-air—turning as a single, silver-flashing sheet of wings—is one of the most breathtaking sights the North East coast has to offer.

But it is vital to remember that these birds aren’t running around for our amusement; they are on a knife-edge survival mission.

These tiny travellers have often flown thousands of miles from their arctic breeding grounds in Siberia or Greenland to overwinter on the Durham Heritage Coast.

Because the winter days are short and the weather is brutal, they need to feed almost continuously to maintain their body heat.

How to watch responsibly:

Give them a wide berth: If you see a flock feeding along the surf, don’t walk directly through them. Walk high up by the dry sand to let them keep hunting.

Keep dogs under control: If Malc or Pete see a flock lift off, their natural instinct is to give chase. But forcing a flock to constantly take flight wastes their precious, irreplaceable energy reserves. Keep your dogs on a short lead or under strict close control whenever you spot waders working the shoreline.

🥾 Expanding Your Coastal Journey

Crimdon Beach is a premier location for coastal wildlife tracking, but it is also a vital link in a much larger walking network.

If you want to expand your day out on the sand into a proper trek, you can easily pick up the wider trails directly from the dunes.
