Migrants Way. Stage 4. Holmpton to Withernsea

 
After wondering if it was worth carrying on with the Migrants Way given that, due to the lockdown, I had missed almost two months of spring migration, I decided to continue. It is not a long drive to the Holderness coast and social isolation is not a problem. I had counted on no walks during the Easter break anyway so it should be relatively easy to catch up.
There were showers as I left home, but once at Homlpton, it had stopped raining. It was a warm, calm morning, with brief sunny spells. I parked on Seaside Road at Holmpton and took in the bird song, and the lushness of the vegetation in the village, before taking the coastal path north.

Although some fields are tilled and sown to the edge of the cliff, there are long stretches with a wide fringe of rough, uncultivated land by the coastal path from Holmpton to Withernsea. This is a haven for a range of farmland birds. Flocks of Linnets twitted by, Skylarks rose and sung, Meadow Pipits did their parachute flights, one with insects in its bill, feeding young. Hirundines were also a plenty, especially Sand Martins, and there are occasional pairs or quartets of Swifts flying north.
 I cross the Runnel, a small drain with a collapsed pillbox. I pass a few farms.

At Intack farm, I have to move to the road as the clifftop path south of Withernsea, by the caravan parks, is not accessible due to coastal erosion and coastal defence works. As I get to the road, I hear a familiar jingle of keys, a Corn Bunting, singing from a wire.  
 Other than the stretch beyond the promenade, there are a few ways down the cliff to the beach which frequented by fishermen, but only the one by The Runnel is easily accessible. The others are steep steps made on the clay, some supported with slabs of concrete.
 As I reach the edge of Withernsea, I hear House Sparrow's sparrowhawk call, when I look up, there is a Sparrowhawk indeed, but mobbing a Red Kite, which is something I wasn't expecting!

This male House Sparrow flew to the sea defences and collected a bill full of insects in no time at all.
I walk by the south promenade until the end of the stage at the Withernsea Pier towers (also called Withernsea Castle or Sandcastle) and after a walk on the beach I decided to walk back by the road and clifftop path. I see a Wheatear at Intack, but only get poor shots.

Featured bird: Sand Martin
Sand Martins are our smalles hirundines. They are a cosmopolitan species, and the European population winters in sub-Saharan Africa. They start arriving in our shores in mid March, so the breeding season must be on its way. On my way back, I stopped by the sewage works, where the nest holes in a small patch of sandy clay were being visited by a dozen Sand Martins. Sand Martins are very adaptable, and quickly take advantage of exposed sandy cliffs as they appear, including piles of sand or sand faces in quarries, or natural cliff falls. They are very common in the Holderness cliffs. Given the speed of coastal erosion, this small colony is probably not very old. The birds enjoyed the bonanza of small beetles, St Marks flies and other insects that were plentiful today in the warm weather. They behaved very socially, like daring each other to stop to check the nest holes, not wanting to land on their own. They have a typical hirundine agile and playful looking flight and their calls are reminiscent of bats'. After some poor attempts to photograph them in flight, a group of them settled on the cliff, where I took these photos.

Doggerland
As sea level dropped due to the build-up of the ice sheets of the last Ice Age, a previously submarine landscape emerged under the shallow North Sea. This now long-drowned world was called Doggerland by Exeter University archaeologist Prof. Bryony Coles, inspired by the Dogger Banks, which was one of the last land areas to disappear. Evidence for the existence of this land appeared in various forms. First, thousands of bones and ancient artefacts have been dredged or trawled from the sea floor by fishermen: bone or antler fish hooks, worked flints, human and animal bones, and mammoth tusks. An artificial beach formed in Holland as part of a land reclamation program, using offshore sand, became a magnet for beachcombers as it was plentiful in remains. Then, the evidence of past existence of submerged forests and peaty deposits on the coast, with roots and stumps of birch, pine and hazel, uncovered during spring tides. Also, the study of the effects of glaciations and seismic surveys of the North Sea floor and evidence of huge changes in sea level, which was more than 100 under the current one during the last glacial maximum (22,000 years ago). At times, this expansive landscape, from Scotland to southern Norway in the north to Denmark, Germany and Belgium in the south, was covered on permafrost, but as the climate warmed in the Holocene, it also had forests, large valleys with rivers, lakes and hills (the Dogger Banks). A huge valley, the ‘Greater Ouse’ as termed by Bryony Coles, flowed north draining the rivers and estuaries from the Wash, the Humber to the Tweed and the Moray Firth, forming a huge alluvial plain on the east side of Doggerland. Around 15,000 years ago, this became a living landscape rich in wildlife and megafauna, eventually connecting the faunas and human cultures of northern Europe and the British Isles. Before the last Ice Age, Doggerland was sparsely populated by Neandertals in search of big game, and later my modern humans. Doggerland’s coastline was very dynamic, but the sea level remained about -100 m until the beginning of the Holocene, when the melt of the American ice sheets resulted in rapid sea level rising and the land was finally drowned. Most of Doggerland was lost by 8000 years ago. The role of the the Storegga landslide on the continental shelf off Norway in the final stages of Doggerland is unclear. This landslide caused a tsunami which flooded coastal areas around the North Sea ca. 8200 years ago. I like to think that, in a way, like the last turret of a sandcastle washed up by a wave, Holderness is one of the last remnants of Doggerland.

Urban birding at Hull: a walk to East Park

When I first came to Hull, I used to cycle to East Park regularly, but lately I have driven to it. Today, for the first time I walked to East Park. It took an hour to get there, another back, but it was quite an enjoyable walk. The car parks in the park were closed, and all facilities, but it was a warm, cloudy, still day, and there were plenty of users, the wide paths made it easy to keep social distancing. I wanted to have a look for dragonflies to the area by the walk-way, but it was closed, so I had to look from the edge of the lake, and none were seen.
Four terrapins were basking in the central island.

On the grassy areas, several families of Greylags and Canada geese were in evidence. They are still too young to form creches, so the different families were keeping their distance from each other.

 A pair of Mute Swans were resting by the shore, not looking like they were trying to breed.
 Several coots were on nests, and a pair had a single chick.
 Near the bridge, I found a young Grey Wagtail, the second year I find fledglings at the park.

Not far away was one of the parents, with a beakfull of insects, calling.
Two Great Crested Grebes were also by the central island.
 I stopped for a snack, almonds. On hearing the crunch of the plastic bag, no less than nine Grey Squirrels came by. They were very happy to share.
 I had never seen a Great Spotted Woodpecker drinking. It was joined by a Mistle thrush. A bit later, on the same spot, a Sparrowhawk tried to drink, but two Mistle Trushes harassed it mercilessly, chasing it away.
 A murder of crows gathered by the boating lake. They were hoping for scraps by a family feeding the geese.
 On the walk back, a peregrine soared over my head putting a nice end to the day's walk.

Urban birding at Hull: a May walk to the Setting Dyke

 A morning walk to the Setting Dyke area. The female mallard has managed to get 8 of her 10 ducklings to a good size (above). The dyke is looking good, many marginal and floating plants growing, the water transparent. I notice some fish, the photos show that they are sticklebacks, males in breeding colours, actively defending nest sites, and females with a full abdomen, ready to lay.

Urban birding at Hull: a May walk to The Deep

A very warm day, with little wind and sunny, I take a walk to The Deep via Freetown Way, and then take the public right of way by the River Hull by Drypool Bridge. It's near midday and it is relatively quiet on the bird front compared to my previous visit (no Osprey!). Walking around town during lockdown it's an interesting experience. Traffic, and noise is much reduced, and there are some people walking, cycling or running. The lack of traffic has an interesting effect on my perception of the landscape, and features I wouldn't had noticed before are now visible, like vision is somehow expanded. This may have something to do with the notable air clarity and transparency, probably due to reduced pollution levels. Of course it is easy to record birds, I don't carry binoculars, just my camera, but song carries far when background noise is reduced.

A little patch of saltmarsh is growing on the river bank bank opposite the Deep, with plenty of small Sea Aster plants establishing on the mud.

A Linnet sings at The Deep car park. On my way back, just by a green path parallel to the A63, I hear a Lesser Whitethroat singing. At least 3 Holly Blues are about, with an Orange Tip and a Speckled Wood butterfly.
