The pull of the clifftop

There are few wildlife experiences as stirring as standing on a windswept headland while thousands of seabirds wheel and cry below. Britain’s rocky coastline, from the chalk stacks of Yorkshire to the granite buttresses of Shetland, hosts some of the most important seabird colonies in Europe. In spring and summer, these cliffs become temporary cities: gannets plunge like white arrows, guillemots jostle for ledges, and puffins whirr in with beaks full of sand eels. You don’t need to be an expert to enjoy them. You do need a little patience, a decent pair of binoculars, and a healthy respect for the birds’ space.

When to go: the seabird season

The season builds from late February and runs through to early August. Gannets are among the first to return, often settling on their nests by March. Guillemots and razorbills follow, with eggs laid from late April. Puffins tend to arrive in April and leave again by late July or early August, once their single chick, or puffling, has fledged. Kittiwakes, fulmars and shags fill in the gaps along the same cliffs.

Timing your visit matters. Early morning is usually best: the light is softer, the wind often lighter, and the birds are busy commuting to and from feeding grounds. Avoid the middle of a hot afternoon, when many birds sit tight on nests and the cliffs can look deceptively empty. Weekdays outside school holidays give you more space at popular viewpoints.

• March to May: courtship, nest-building and egg-laying. Lots of noise and movement.
• June to mid-July: chicks everywhere. Gannet plunge-diving is at its most dramatic.
• Late July to August: fledging. Puffins disappear quietly; guillemot chicks jump from ledges at dusk.

Meet the cast: gannets, guillemots and puffins

Northern gannets are unmistakable: large, brilliant white with black wingtips and a creamy-yellow head. Watch for their spectacular plunge-dives, folding back their wings just before hitting the water at speed. They nest in dense, noisy stacks, often on offshore islands and remote headlands.

Guillemots are the cliff’s commuters: slender, chocolate-brown above and white below, standing upright on narrow ledges. Some show a thin white ring around the eye and a white line behind it, known as the “bridled” form. Razorbills look similar but are stockier, with a thicker, blunt bill crossed by a white line. Puffins are the crowd-pleasers: dumpy, black-and-white, with a rainbow-coloured bill in summer. They nest in burrows or crevices, often on grassy slopes above the cliffs, and fly with a frantic whirr of wings.

• Gannet: large, white, yellow head; dramatic plunge-diver.
• Guillemot: slim, brown, upright; often in tight packs on ledges.
• Razorbill: like a guillemot but thicker-billed and shorter-necked.
• Puffin: small, colourful bill, orange legs; flies fast and low.
• Kittiwake: small gull with black wingtips and a ringing “kitti-wake” call.

Binoculars and fieldcraft: getting close without getting too close

A good pair of binoculars transforms a clifftop visit. Look for 8x42 or 10x42 magnification: the first number is magnification, the second is the diameter of the front lens in millimetres. The larger the front lens, the more light they gather, which helps in dull British weather. A spotting scope on a tripod is excellent for watching rafts of birds on the sea, but a decent pair of binoculars will keep you mobile and warm.

However you watch, keep a respectful distance. Disturbance is the biggest threat to breeding seabirds. If birds begin alarm-calling, head-bobbing, or taking off in a panic, you are too close. Stay on marked paths and viewpoints, even if a ledge looks temptingly accessible. Keep dogs on a short lead, and never fly a drone near a colony. Drones cause real distress and are illegal in many sensitive areas. If you want a close-up photograph, use a telephoto lens rather than creeping nearer. A flushed bird may abandon its egg or chick, exposing it to predators and bad weather.

Reading the cliffs: tides, weather and safety

Rocky coastlines are beautiful but unforgiving. Check tide times before you set out, especially if you plan to walk below the cliffs. Rising tides can cut off headlands and fill narrow coves quickly. Wear sturdy footwear with good grip; sea-sprayed rock is slippery even when dry. Wind is another factor: a sudden gust on an exposed headland can knock you off balance, so stay back from loose edges and never turn your back on the sea.

Weather also affects what you see. A calm, bright morning after a night of rain often brings seabirds close inshore to feed. Strong onshore winds can push birds towards the coast, but they also make cliff-top watching uncomfortable and dangerous. If a colony is visibly agitated, move away quietly and find another vantage point. The birds’ needs come first.

Wherever you go, let the birds come to you. Find a comfortable spot, raise your binoculars, and wait. The cliffs will reward you with plunge-dives, squabbles, and the constant, thrilling noise of a seabird colony at full tilt. Tread lightly, watch closely, and leave nothing but footprints on the path.
