Autumn is the coast at its most restless. Birds are pouring south and west out of Scandinavia, Siberia and the high Arctic, and the UK sits directly in the way. A single night of the right wind can put a yellow-browed warbler in a sycamore behind a car park, or push thousands of pink-footed geese over a Lancashire marsh at first light.
The trick is knowing where to stand and when. Here is how to plan a trip around the coast this autumn, and what you might reasonably expect to see.
Start with the weather, not the map
Wind direction decides your day far more than which reserve you choose. In late September and October, a north-easterly airstream funnelling down the North Sea carries migrants from Scandinavia straight onto the east coast. Expect drift migrants — redstarts, pied flycatchers, whinchats, wrynecks if you are lucky — grounded in the first scrub they meet.
Switch to a westerly gale and the action moves to the opposite side of the country. Atlantic lows push seabirds close inshore off Cornwall, Pembrokeshire, the Irish Sea and western Scotland, and headlands that were quiet the week before suddenly produce a steady passage of shearwaters and skuas.
High pressure with light winds and clear skies is a different game again. Nothing gets grounded, but visible migration goes into overdrive: finches, pipits, wagtails and, later, redwings and fieldfares moving over headlands in a constant trickle from dawn.
A north-easterly in late September is worth more than any new pair of binoculars.
Three things to check the night before
- Wind direction and strength at the coast you plan to visit, not at home — sea breezes can override the inland forecast by mid-morning.
- Rain and mist over the North Sea or the Irish Sea. Poor visibility over water forces migrants to make landfall rather than carry on.
- Tide times. An incoming tide pushes waders into roost and brings seabirds closer; a falling tide over mudflats can leave you staring at empty ooze.
East coast: the drift migrant highway
The stretch from Holy Island and St Abb's Head down through Druridge Bay, Flamborough Head, Spurn Point and the Norfolk coast is the country's premier autumn corridor. Spurn and Flamborough both offer the combination that matters: a headland to concentrate tired birds, and plenty of sheltered cover for them to drop into.
Work the vegetation rather than the open shore. Elder, sycamore, willow scrub, the lee side of a hedge, a stand of sea buckthorn — these are where a fall of migrants collects. Walk slowly, listen for contact calls, and resist the urge to stride through the best-looking patch first. Many rarities are found by the second or third pass, when the bird has settled again.
Realistic September and October targets include goldcrests in numbers, robins and blackbirds fresh in from the continent, bramblings, twite and Lapland buntings on saltmarsh edges, and shorelarks on shingle later in the season. Rarer fare — red-breasted flycatcher, barred warbler, bluethroat — is a bonus, not a plan.
Seawatching the great headlands
Seawatching rewards patience and a decent scope. Pick a spot with height and a clear view of the horizon: Flamborough, Filey Brigg, Whitburn Steel and Hartlepool on the east; St Ives, Pendeen, Prawle Point, Bardsey and Rhosneigr on the west.
Timing varies by species. Manx shearwaters peak in August and early September. Sooty shearwaters follow through September, with great and Arctic skuas mixed in. Pomarine skuas are more of an October and November bird, often after a spell of strong westerlies. Leach's petrels turn up in the Irish Sea during gales, and Sabine's gulls are a classic September and October prize on either coast.
Log what passes in set blocks of time, note direction of travel, and stay put through a shower. Passage often resumes the moment the rain clears.
Estuaries and mudflats: the quiet spectacle
Not every autumn day needs a rarity. The big estuaries — Morecambe Bay, the Dee, the Severn, the Wash, Strangford Lough, Belfast Lough, Montrose Basin — fill up with wintering birds through October and November, and the sheer numbers are worth the trip on their own.
Pink-footed geese arrive from Iceland in waves, often heard long before they are seen. Brent geese, wigeon and teal pile in behind them. On the mud and sand: knot, dunlin, bar-tailed godwit, grey plover, sanderling, turnstone and curlew, all pushed towards the shore as the tide rises.
Find a high-tide roost and arrive an hour before the water covers it. Keep well back, stay low, and keep dogs on a lead. Flushing a roost costs birds energy they have spent weeks building up.
Headlands and islands for arrivals
Southern and western headlands — Portland Bill, Hengistbury Head, Dungeness, Selsey Bill, the Isles of Scilly — catch birds arriving from the south and east, and are excellent for watching migration in the air rather than in the bushes. Meadow pipits, alba wagtails, skylarks, swallows and later chaffinches and thrushes all move through in visible streams.
Offshore islands such as Bardsey, Skokholm and the Isle of May concentrate whatever is passing, which is why ringers value them so highly. If you visit, follow the island's rules, keep to paths and never enter roped-off areas.
Kit, timing and fieldcraft
- Get there before dawn. The first hour after sunrise is when grounded migrants are most visible and visible migration is busiest.
- Take waterproofs and warm layers. Coastal headlands in October are cold, wet and windy, often all three at once.
- Carry a scope if you can, plus binoculars you can hold steady in wind. A lightweight tripod makes a real difference on a seawatch.
- Learn a few calls. Yellow-browed warbler, redwing and brambling calls will find you more birds than scanning ever will.
- Keep notes. Date, wind, tide and what you saw. Patterns will emerge after a couple of seasons that no forecast can give you.
Making a day of it
Choose one stretch of coast and learn it properly rather than chasing news across three counties. Check tide tables, plan your arrival around first light, and give yourself at least an hour on a seawatch before you walk the scrub. A flask and a decent pair of boots will do more for your day than any gadget.
Above all, keep your expectations modest and your eyes open. Most autumn days produce common birds in wonderful numbers, and that is the real spectacle. Every so often the wind shifts, the sky fills, and something unexpected drops into the hedge beside you.
