Train trip: Walking from Bempton to Filey

This trip had been on my wish list of walks for a while, and today, sunny weather and ebbing tide, I took the 7:25 train to Bempton. On the way, on a field north of Cottingham I manage a photo of nine Roe Deer. A Yellowhammer sits tight while a male Sparrowhawh flies past over my head on Cliff road at Bempton. A Brown Hare seems to be following a track on a field, zig-zagging and eventually coming quite close.

I sit watching the birds at the Bempton Cliffs RSPB reserve feeders while I wait for the cafe to open, at 9:30. After a hot drink, I'm ready for the walk. There seems to be fewer birds on the cliffs than on our visit a couple of weeks ago, but it is still busy. I don't linger much, but a Stonechat by the military area is nice.

I leave the reserve. The cliff is very exposed to the westerly wind. Despite this, Linnets and Skylarks are feeding in the fields. Two Buzzards are playing with the wind on a ridge, one of them seem to be carrying a stick on its talons. A Peregrine swoops at one of them, and then hangs from the air over the cliff edge, hovering.

Shortly after, the path down to Speeton Sands is being reprofiled and repaired with a small digger. It's relatively easy going until the steep steps down the ravine onto the beach by Black Cliff, which are in need of some TLC, the clay having eroded behind the retaining boards. The ravine highest humidity shows in a diversity of ferns and some tree cover in the shape of sycamores. There is a nice pond on a shelf near the ravine.

Quite a lot of Cuttlefish bones on the beach, the largest about 17 cm.

It is a walk of two halves, the second part taking place along the long exposed beach, at low tide. It is much sheltered with barely any noticeable wind on the beach. After a quick lunch stop I carry on beach combing and make it to Filey with just enough time to grab a hot chocolate in the cafe and board my train back home.

Walk information. Distance between the stations: almost 17 km. Toilet facilities and cafes at Bempton, Hunmanby Gap and Filey. The walk is best attempted with an ebbing tide, as there is barely any beach at high tide. Poor accessibility and hard going, especially on the way down to the beach.

Wilsthorpe Dunes and Fraisthorpe Beach with Hull Nats

I was keen to visit Wilsthorpe dunes on a warm summer day to check on its invertebrates. Other than at Spurn, sand dunes is not a common habitat in East Yorkshire, and I was curious to see if this small patch of dunes at the top of Bridlington Bay held something of interest. Today's was a day visit with Hull Nats. It was warm, with a breeze and sunny spells. I had brought my bat detector and checked for bush crickets, both Long-Winged Coneheads and Roesel's sung from the more grassy areas.

We spend some time identifying the dune grasses: Lyme grass, silver blue at the front, and Sea Couch in the next fringe. On a low hump by the edge of the dune we identified Sand Couch, with long, creeping rhizomes.

Both Long-winged Bush-cricket and Roesel's were present. A possible Short-winged conenead on a dune slack coudn't be confirmed.
It's worth looking up and admire the setting every now and then. The Flamborough headland is in the horizon.
Gannets were fishing offshore.
Many dry seedheads of Hounds Tongue and young rosettes of its distinctive leaves.
Sandwich Terns. This time of year a visit to the dunes has the background sounds of calling Sandwich Tern juveniles chasing adults.
Plenty of Linnets and Goldfinches feeding on thistle seeds.
I was very pleased to spot a Sand Bear Wolf Spider, Arctosa perita, at the front of the dune by the anti-tank blocks where we had our lunch. I've only previously recorded it in Spurn.

Some chicks looking like they are close to fledge are still present at the Sand Martin colony at Fraisthorpe.

We saw a flock of 10 Ringed Plovers, this one lander a bit nervous as the tide was high amongst the passers by.
Common Field Grasshopper.
I believe this is a sand digger wasp, Ammophila sabulosa. The adult female captures and paralises caterpillars and stocks nests she digs in the sand with those, and then lays eggs on the caterpillars.
A dune robber fly, Philonicus albiceps.
We found a few clumps of Sea Rocket and other coastal dune specialists.
Saltwort, Salsola kali.
This was the most bizarre find of the day, a mummified rabbit that Andy uncovered at the beach.

Last interglacial coast trail. Stage 8: Bridlington to Sewerby

Today is the last stage in the Interglacial coast trail, a circular walk, the main stretch is via the streets of Bridlington, then descending at Sewerby steps, and returning by the beach. The weather forecast threatens storms at lunch time, but fortunately there are only a couple of short, light showers and it is altogether a pleasant day, though windier in the afternoon.

I get to Bridlington station at 9:00 am, and take Bessingby road and then St Johns Avenue. I can see Bessingby Hill in front of me. In the last interglacial this stretch of the coast would have been tricky to cross, with the small Gypsey Race haven surrounded by marshes and pools. At low tide sand banks and shingle bars might have allowed passage across. There is a small stretch of the Gypsey Race visible from St John's Walk, a straight, embanked and gated stream. The final part of the stream was only daylighted recently to make the Gypsey Race park, and it has been heavily managed since historical times, with four watermills and mill ponds directing its waters to grind flour and bone, cut wood andeven produce electricity.

The remainder of the walk to Sewerby is uneventful. Swifts, Swallows flying over, Jackdaws and Herring Gulls on nests on roofs. A light shower at Sewerby, then the sun shines and I have a snack at the top of the Sewerby steps. Afterwards, I descend to the beach.

The tide has turned and is now ebbing. An Oystercatcher catches something large and a Herring Gull pursues it until I lose them from sight. A large flock of House Martins pick mud on a steep slope atop the cliff, from the glacial till. There is a population of House Martins in Flamborough that nests on the cliffs themselves, probably the ancestral nest sites for the species before they discovered houses. There is a spring at the beach, and it is a busy spot with Kittiwakes and Herring Gulls taking baths. The Kittiwakes are picking bits of seaweed and dropping them, some fly off with them, they are building or repairing their nests. Some Sandwich Terns pass by, tempted to land with the gulls, but deciding to carry on fishing.

There is a lot of water seeping out of the gravels along the cliff as I walk towards Bridlington. A forest of Great Horsetails grows on the wet slopes down to the tideline. There is a little rivulet where tufa forms platforms and shallow little pools where birds often gather to bathe. Today two Greenfiches and a Whitethroat were on it. It's busy at the sea front, being Bank Holiday. I wander around the harbour for a while and then I get to the station to catch my train back.

Sewerby Palaeobeach exposure.

The Sewerby buried cliff

By the bottom of Sewerby steps is Rock Ends, where the chalk platform at the bottom of the cliffs gives way to North Sands. On the cliff itself, the chalk is replaced by glacial tills and gravels. The Sewerby paleo beach exposure is in the junction between chalk cliff and till and gravels. Unfortunately, the exposure is not very obvious today, recent rains have caused slips and much of the chalk is covered on mud. A bit of blown sand and chalk rubble is visible, but no beach shingle. Some of the raised beach formed by chalk shingle might be visible if you are lucky, higher than the current high water mark. Sands covering this paleobeach, from ancient dunes, have been dated from the Ipswichian, 120,000 years ago. This site, together with Hessle, is the only in East Yorkshire where the interglacial cliff emerges from its covering of glacial till and gravels. It is not only a geological site but an important palaeontological site.

The fossils

Fishermen had found fossils at the base of the Sewerby cliffs since the beginning of the 19th century, including the tusk of a straight-tusked elephant. After winter storms cleared the clay covering the exposure, Mortimer in 1884, alerted by Lamplugh, did some searching in the area and found bison bones. Later, Lamplugh organised an excavations with a budget of £10 of the time, in 1887. Altogether, the megafauna fauna identified from the fossils found at Sewerby, which was later revised by Boylan, is typically Ipswichian and include Cave Hyena, Bear, Straight-tusked Elephant, Narrow-nosed Rhino, Hippo, Giant Elk, and Bison.

Straight-tusked Elephant

The herd had been feeding all morning deep into the wooded pastures on the Flamborough headland, and are now marching towards the stream to drink. They follow a well-trodden track that runs roughly along where the B1255 road to Bridlington is now, avoiding the steep ravine of Danes Dyke. The matriarch, the largest and oldest elephant, distinctive for the missing tip of her right tusk, leads the way. She is sniffing the air for lions or hyenas, but doesn’t seem too anxious. The track now opens up on the valley bottom, into a grassy damp meadow, the work of the pod of hippos, which is now wallowing and snorting on the shallows of the Gypsey Race Haven.

Given the popularity of elephants, it is puzzling that the Straight-tusked Elephant, Palaeoloxodon antiquus, is so neglected compared to the other extinct European species, the Woolly Mammoth. The Straight-tusked Elephant was one of the largest terrestrial mammals to have existed, with individuals reaching over 4 m in height at the shoulder and males weighing up to 13 metric tons. It had - you guessed! - relatively straight tusks, and this was an easy way for palaeontologists to tell fossils of this species apart from the Woolly Mammoth, which had strongly curved tusks. Several molars and tusk fragments were found in excavations at Sewerby Cliff. Notably, there are little or no cave paintings that can represent Straigth-tusked Elephants, contrasting with a rich portable art and mural representations of Woolly Mammoths. A detailed reconstruction in a recent article by Larramendi and colleagues shows what the elephant might have looked like, which was reproduced as an Eofauna model depicted in the photo above.

The Straight-tusked Elephant was closely related to African Elephants and inhabited Europe in the last interglacial. It thrived during interglacial periods across Europe as far north as Yorkshire in the UK, and retreated to the Mediterranean during glacial periods. Both Mammoth and Straight-tusked Elephants coexisted in the transition periods between glacials and interglacials. It inhabited deciduous woodlands or Mediterranean evergreen woodland, as opposed to the cold-adapted, open steppe or tundra of the Woolly Mammoth. The pattern of tooth wear indicates that it was a browser, rather than a grazer. A very interesting feature of the straight-tusked elephant is its mixed ancestry: it is closely related to the extant African elephants, but it has some ancestry from the Woolly Mammoth and African Forest Elephant too.

The tip of a tusk of a Straight-tusk elephant excavated from Sewerby in 1879, that can be seen at the Hull and East riding Museum.

Straight-tusked elephants would have lived in multi-generational matriarchal herds with young. The adult males would leave the herd and join others forming bachelor herds, or become solitary, like living African elephants today. The species was hunted across Europe by several human species during the last half million years. In the last interglacial it was regularly hunted by the Neanderthals in mainland Europe. In human-free Britain, the Straight-tusked Elephants of the last interglacial didn’t have to worry about humans, only Cave Lions or Cave Hyenas might have posed a risk to young individuals, as evidenced by the finding of milk molars belonging to Straight tusked Elephant young in Kirkdale and Victoria caves, likely predated by hyenas.

Can I see them?

Unfortunately, Straight-tusked Elephants went extinct during the last glaciation, about 37,000 years ago, probably because the populations in the Mediterranean refugia at the height of the glaciation were small. There was little overlap with the newly arrived modern humans, but it’s possible that hunting by modern humans might have caused their ultimate demise. You can see a real fossil tusk of a Straight-tusked Elephant from Sewerby at the East Riding Museum in Hull, or you could follow the Elephant Trail along Albany Street and Spring Bank West in Hull.

Walk details. Distance: 9 km circular trip. From Bridlington train station walk north along Bessingby Road and then turn right at St John's Avenue and then to Brookand Road. Take a right to High Street and continue towards Bridlington Priory Church, leave the church on your right and continue along Sewerby Road to Sewerby Village. There are refreshments and public toilets in Sewerby Hall (free access in the winter season, but entrance fee in the summer, check website for details), several along North Beach, and at the train station. The return is descending the Sewerby Steps, and walking back along the beach, harbour, and the Gypsey Race Park to the train station.
