Migrants Way. Stage 17. North Landing to Bempton

The day started cold. Ominous dark clouds remind me that rain could happen at any point, but it warmed up, and the skies cleared, leaving a lovely morning for a walk. A Kestrel hunts over the long grass, and a lone swift flies with the resident House Martins. Some Jackdaws feed on the still empty car park at North Landing. The tide is high, a spring tide too, of over 7 m, little beach left at the landing. 
 After a peek at the landing, I take the coastal path north. I'm glad I started early and I can enjoy the solitude of the cliffs. Groups of Gannets fly north in V formation. Fulmars fly incessantly by the cliffs, circling, wavering their wings when almost touching the rocks with their outstretched feet. Some Fulmar chicks can be seen hunkered down on their nests.

 I take the steps fown Holmes Gut, a small ravine clothed with scrub. I head water trickling down, but it runs under the brambles and hairy willowherb. Goldfinches and Linnets sit chattering and grooming on the gorse. By Holmes Gut there is a large patch of flowering mint with some fleabane. It is teeming with butterflies: my first Painted Lady of the year, Red Admiral, too many Small Tortoiseshells to count, and plenty of Silver Y moths, a Small Copper and two Common Blue. A highland cow looks on from the field above.

Nabs and Nooks
In the first part of the walk the chalky cliffs are rugged, morphed by the erosion of rough seas: first broken into fissures, then into caves and arches. There are two accessible coves, North Landing, with with its slipway for cobbles, and Thornwick bay, but from there on many little coves (known as nooks or newks) and promontories (nabs). From Thornwick bay onwards there is barely any beach or intertidal platform at the bottom of the cliffs, the cliffs plunging into the depths, the sea constantly lapping the rocks by the cliff base. I look at the names on my map, detailing each feature of the cliffs: Close Nooks, Gull Nook, White Corner, Noon Nook, Cat Nab, Wandale Nab...

Danes Dyke
The cliff climbs in height steadily, I'm approaching Danes Dyke, a line of trees marks this ancient monument from a distance. When I get to it, I scramble to the top and I am rewarded with an amazing view of the whole of the peninsula, photos don't really do it justice. 

The cliffs by the north side of the dyke are already part of Bempton Cliffs RSPB nature reserve. The acrid smell of guano and the cackling, rattling calls of gannets advertise the reserve.
Seabird city
The chalk cliffs from North Landing to Bempton hold the largest mainland seabird colony in the UK, which is also of international importance. Eight seabirds breed on the cliffs: Fulmar, Gannet, Kittiwake, Herring Gull, Guillemot, Razorbill, Puffins, and Shag. Given their conservation value for seabirds, there are regular counts, with the the 2017 census giving totals of over 200,000 breeding birds
I stop at the clifftop viewpoint at Staple Newk. This affords an aerial view of the gannet colony: the 'gugas' or gannet chicks are the darker birds, contrasting with the white adults. Nests are regularly spaced, just distant enough to avoid the bill of the neighbours. Gugas at Staple Newk are most now fully feathered, although there are chicks in a range of stages of growth, some all covered on down, others with down only on their heads in other areas of the cliffs. Gannets and Fulmars are the last chicks to fledge the cliffs, most Kittiwakes and auks have already gone.

The gugas at Staple Newk are mostly feathered and ready to fledge. When checking the photo I noticed one of the adults has a red ring marked 'N3'. David Aitken on twitter confirmed that this individual was ringed in 2018 as part of a study and has returned to the cliffs every year since.

This was the youngest guga I saw today.
The cliffs were busy with non breeding Gannets too. Gannets don't usually breed until their fifth years, and they gain their adult plumage in stages and can be aged by the extent of black on body. Non-breeders roam widely but eventually return to their natal colony, assembling in groups called 'clubs'. There they do a fair amount of displaying, helping them with their social skills and also with pair formation.

Gannets pair for life. The partners engage in billing and grooming display. This is likely to be a young non-breeding pair. They are grooming pair after the 'territorial' dispute with the bird behind.

After a coffee and snack at the RSPB visitor centre, I walk around the back of the reserve. By the car park, plenty of Willow Warblers feeding on the hedgerows and trees. A male common darter patrols the pond.
It's time to walk back. The sun is shining and the views are well worth walking the same way I came.

Migrants
Flamborough is a top migration hotspot and the area is very well recorded, with the Flamborough Bird Observatory (FBO) engaged in bird ringing, sea watching, breeding bird surveys and producing an annual report detailing species summaries and articles on the activities of the observatory. 
It is autumn migration season now and birds (an some insects) are already returning to their winter quarters, some after having finished breeding. 
Painted Lady, a migratory butterfly. I had my first Painted Ladies of the year today, it hasn't been a great year for them. 
Dozens of silver Y also fed on mint and knapweed. This is a strongly migrant moth.
Two Wheatears fed on a grassy field, but they had no peace, as a family of wagtails were not very happy to share and kept harassing them.

Near Holmes Gut, I spotted some distant birds flycatching. There were two Whinchats, my first this year.

Featured bird: Northern Gannet
The Gannet is the largest and one of the most spectacular seabirds in Europe. Being heavy birds, they need updrafts to take flight, which is one of the reasons why they breed in rocky islands and sheer cliffs, another being to be safe from predation and human disturbance. They are highly colonial, with breeding populations concentrating in a few gannetries, that have some times been occupied for centuries. Bempton holds the only English mainland gannetry, with the latest census (2017) giving more than 13,000 pairs and over 1000 non-breeding individuals. Despite its Amber status in the UK, the gannetry at Bempton cliffs has been increasing steadily since it formed in the early 1960s, although nesting pairs had been seen regularly since as early as 1925, with a few young occasionally raised. Tracking studies have shown Bempton Gannets fishing trips can take them 100s of km away from the colony, all round the Holderness and North Yorkshire coasts and as far as Dogger Bank. Gannets are partial migrants. Although individuals can be seen year round off the Holderness coast, many adults overwinter in the Western Mediterranean and the Bay of Biscay while younger birds range further afield, reaching the West and Central African coasts.

Walk Information

Migrants Way. Stage 16. Flamborough Head

A family walk today, we head to Flamborough village, the start of this circular walk for the Migrants Way. It is sunny and warm, with a light breeze. We walk along South Sea Road to reach South Landing, where I left the way last week. The plan is to walk all round the peninsula on the cliff top path, until we get to North Landing, then back to Flamborough village.
South Landing 
We descend the slope on the road to the landing. The ravine at South Landing is an ancient valley, with a glacial till infill, probably dating at least from the previous interglacial. The tide is right out, exposing the intertidal platform and sandy beach, and two parallel rocky spits, possibly the remains of an old pier?
South Landing. Two parallel strips of rocks are visible at low tide.
After a quick stop at the beach, we climb the steep steps to take the clifftop path. There are so many Wall Browns about, flitting alongside the path, briefly settling to bask.

 House Martins are a constant presence along the walk, probably indicating the presence of nests on the cliffs all round the peninsula. A Kestrel hangs from the sky ahead of us, immobile, over the cliff. Some Herring Gulls passing by swipe at it. A Fulmar circles around the cliffs, at some point making a low pass over the wheat, an incongruent image that I fail to capture with my camera.
I hadn't checked the tide, but it was a nice surprise that it was so low. It does make a difference to have the intertidal platform exposed even when walking on the clifftop, as there is so much more to see. A Grey Heron flying along the cliffs sends the loafing gulls flying. Oystercatchers and Curlews feed on the rocks. The path is relatively flat and straight, flanked by a grassy strip on the cliff side and arable fields. Occasionally, small creeks have more scrubby vegetation and need to be crossed with steps, or walked around.
Cretaceous chalk
The chalk forming the cliffs now exposed from Sewerby to Reighton developed on shallow, very warm seas between 100 and 70 million years ago. The skeletons of tiny planktonic organisms, mostly those of Coccolithophores a single cell algae surrounded by calcite plates, rained on the sediments over millions of years. This lime-rich mud at the bottom of the sea got transformed by pressure and heat into chalk. At Bridlington Bay the chalk bed is now between -30 to -35 m under sea level. The chalk was formerly more extensive, then much of it was eroded, leaving the ridge of the Wolds and Flamborough Headland.
Rising over fields of barley and wheat, we can see the lighthouse at Flamborough Head. 
Seals
I notice some odd lumps on the rocks jutting from the peninsula, they are seals hauled on the rocks in clumps! We count over 60, but there are probably about a 100. Most of them are Grey Seals, with a few  some common seals too. We can hear them howling, as they are jostling for position on the rocks, and many are on the edge of rocky shelves comically trying not to get their flippers wet. It is quite common to see Seals around Flamborough, but the most I've seen there is six or seven, this is by far the largest seal concentration I've seen in East Yorkshire.



A menacing raincloud is coming our way. We are now at the head of the cape, the lighthouse just by us. It is only light rain and it stops soon.
We stop for lunch on a pill box by the Golf Course, overlooking Selwicks bay and the sea. 
A cluster of Gorse Shieldbugs, Piezodorus lituratus, including adults, and nymphs of various sizes beautifully camouflaged on gorse seedheads.
Cormorants and Shags pass by over the sea. Gannets fly straight east in small groups, almost touching the water with their wings.
We carry on the clifftop path. It is getting busier now with walkers and there are many stops to let people pass socially distancing. Another rain cloud is coming. We get to Breil Nook (top shot), a beautiful nook in the cliffs with a stack and some rocks sticking over the water. A handful of Kittiwake chicks are still on nests. Seven shags are on the rocks and a Fulmar chick is briefly in the company to both its parents. Other Fulmars circle the cliffs.

As we are arriving at North Landing, a Short-eared Owl flies over us towards the lighthouse, I manage a single sharp shot. What a wonderful sighting!
North Landing is very busy, the car park almost full, buses bringing even more visitors, so we don't hang around much. A large Starling flock flies around the houses by the landing. It is a half an hour walk by the road back to the car from North Landing to Flambororugh Village.

Featured bird: Fulmar
Fulmars underwent a spectacular range expansion and population increase, from the only place where they bred in St Kilda to then Shetland and steady colonisation of all rocky British shores. According to Nelson, before the 1900 they were rare winter and autumn visitors, most frequently met by offshore fishermen, who gave them the name of Mollemoke. As described in the monograph by Fisher, which documented the expansion around the UK, Fulmars first bred in the cliffs of Flamborough and Bempton around a century ago, the first eggs were collected by cliff climmers in 1922. Since then, they have steadily increased their numbers. However, Fulmars have declined 38% during the present century in the UK, and also at Flamborough and Bempton, so that they are now Amber listed, and considered as endangered in Europe.

Walk information
10 km circular. Start and end at Flamborough Mereside, TA228705 (free parking). Toilets on South Landing (Living Seas Centre), and Flamborough Lighthouse and North Landing car parks. Access to beach at South Landing, Thornwick Bay and North Landing, best with low tides.
