Wilberforce Wood, Foredyke Green and Noddle Hill

A gloomy day with a light, but cold breeze, I catch a bus to Kignswood. I potter around the car park, where a male Pied Wagtail sings and feeds. I walk towards Midmeredales. The path is very muddy and flooded and at some point by a ditch, the water is too deep for wellies, so I have to turn round and walk along Kesteven Way, popping into the woods by the entrances. A flock of 40+ Siskins feeds on Alders by the temporary pond, while Goldfinches nearby are on the Teasels and Burdocks. It is being an irruption year for Siskins, they are everywhere and I find some in every outing, they favour both Italian Alder, widely planted along avenues in the city, and Common Alder in more seminatural scrub. 

The woodland is waterlogged or flooded. It was planted in the turn of the Millennium, I participated in a planting session around December 2008, where there were few trees.

Foredyke Green Pond, most of the perimeter path is flooded. 

A dog walker tells me of a sighting of a Mink hunting a rabbit before Asda was built and how many nights, as he checks his front garden, a Barn Owl flies by, and turns its head to look at him as if saying good night.

A pair of Mallards were the only birds of note at Foredyke Green Pond.

I walk up the Foredyke Stream. A mixed flock of gulls with some Lesser Black-backed Gulls are in the floods, but no Lapwings today. A Marsh Harried flies over quite low and I lose it quickly. I walk around the pumping station, the area has been flooded, but is now passable. At the top feeders, no evidence of Tree Sparrows or Yellowhammers, but I flush a Kingfisher at the Holderness Drain. I have my lunch by the pond feeders. Great Tits, Blue Tits, Dunnocks, Long Tailed Tits and a Robin keep me company. As I leave, I hear and see some Siskins on the Alders by the pond. They are indeed everywhere!

Last interglacial coast trail. Stage 2: Cottingham to Beverley

It is a very cold overcast day, but I take the bus to the start point of the second stage of the Last Interglacial Trail at Northgate, Cottingham. The first part of the walk follows Park Lane across Cottingham Parks. It is hard to discern any trace of a cliff on the ground, but the fact that ditches run steeply to the east indicates I'm walking near the bottom of the cliff, not on the chalky old cliff, which is too permeable for running water. Here the old sea cliff lays buried by till and other glacial deposits.

After walking on the surfaced road by a series of greenhouses I get to Burn Park Cottages and then Burn Park Farm, with its gnarled walnut trees. A very confiding Kestrel greets me on the ground and then on the farm sign (above). Chaffinches sing from the hedges.

I find the first Dog's Mercury of the year growing by a ditch on the eastern side of Jillywoods, together with the abundant Cuckoo's Pint, remnant plants of the northern woods of Cottingham.

A chalky path by Poplar Farm.

At Poplar Farm, seven Pied Wagtails feed on a flooded field. The paths have been very passable, only one section by a flood more muddy.

A road bridge crosses the A1079. Skylarks sing. The area is known as Beverley Parks, as there was parkland and a hall, White Hall.

Pond at Beverley Parks. There are scattered ponds in this area that are actually springs. I wonder if these springs would have been under the sea of the Ipswichian or exposed on the shoreline.

A lone oak on the last fields before Beverley by Sheperd's Lane. This is a very rapidly developing area, the new houses in the background.

As I arrive to the end of the walk at Beverley Minster, the bells ring midday (a few minutes early, all to be said!), and I make my way to a cafe for lunch before taking the bus back home.

In contrast to today's quiet and relaxing walk, an amble in this area in Ipswichian times must have been terrifying, not least by the presence of Cave Lions and the other large carnivore of the time: Cave Hyenas.

No laughing stock: Cave Hyenas

Hyenas are an abundant and widespread component of the Ipswichian fauna. One of the key sites for British fossil hyenas is a Yorkshire site with outstanding archaeological and historical significance: Kirkdale Cave, near Kirkbymoorside. The cave was excavated in 1821 by Reverend William Buckland, having been alerted to the presence of fossils in the cave. An eccentric character, the first ever lecturer in Geology, and theologian from Oxford University, he approached the excavation and interpretation with sharp logic and innovative experimental approaches for the time. In a fascinating article on the cave, a brilliant example of paleontological analysis, he made a very good case that hyenas used the cave as a den, and the fragmented bones of a range of animals, including hippo, rhino, deer and elephant, amongst others, represented the remains of prey, having been gnawed by the powerful jaws of the hyenas. Buckland even made some experiments with a captive Spotted Hyena from a travelling zoo to test some of his interpretations regarding the fossilised faeces he found (he went on to coin the term ‘coprolites’ to refer to them). After feeding bones to the captive Hyena and examining its faeces he could conclusively determine that the coprolites belonged indeed to Hyenas. Hyenas had dragged hippo remains into their caves or the remains were found as part of their faeces.

From Buckland:

‘It must already appear probable, from the facts above described, particularly from the comminuted state and apparently gnawed condition of the bones, that the cave at Kirkdale was, during a long succession of years, inhabited as a den by hyenas, and that they dragged into its recesses the other animal bodies whose remains are found mixed indiscriminately with their own; and this conjecture is rendered almost certain by the discovery I made, of many small balls of the solid calcareous excrement of an animal that had fed on bone’ 

‘I do not know what more conclusive evidence than this can be added to the facts already enumerated, to show that the hyaenas inhabited this cave, and were the agents by which the teeth and bones of the other animals were there collected’

Another Yorkshire cave with Ipswichian deposits, and likely another hyena den at that time is Victoria Cave, near Settle. A similar fauna with Hyena, Hippo and Straight-tusked Elephants, and crucially, no evidence of humans. The time period where the deposits formed at Victoria Cave was dated by Uranium series to 120,000 years ago, similarly at Kirkdale Cave was dated as 121,000 ± 4000 yr BP, confirming their Ipswichian age. Modern hyenas den in burrows of other animals, that they enlarge, so the fact that they used these caves preserved a treasure trove of fossils of the fauna of the time. More exposed sites on plains and river terraces were subsequently erased by the last ice age.

Hyenas are a highly intelligent, social species with females being dominant to males. They live in clans of related females and unrelated males, and hunt cooperatively. Recent studies on Spotted Hyena indicate that they are more likely to hunt than to scavenge and they frequently lose prey to lions, although they also steal prey sometimes from lions too. Cooperative hunting allows them to be able to tackle large prey. Hyenas can commute long distances between their dens and feeding grounds, round trips of 80 km have been documented. So a trip of the Kirkdale clan to the Wolds wouldn't be out of the question.

Where can I see them?

Cave Hyenas (Crocuta crocuta spelaea) were a subspecies of the Spotted Hyena, which became extinct in Europe c. 29.000 BP. Spotted Hyenas are currently distributed in Sub Saharan Africa. A presumed Spotted Hyena cave painting at Chauvet Cave has been deemed to be a skinny cave bear, although its legs look very hyena-like to me. A clan of Spotted Hyenas can be seen at Yorkshire Wildlife Park. Cave Hyena fossils from Kirkdale can be seen at the Rotunda Museum in Scarborough and the Yorkshire Museum at York.

Alkborough Flats with Hull Nats

We were extremely lucky with our monthly field excursion at the Hull Natural History Society on Sunday: long sunny spells and barely a breeze. We gathered at the newly resurfaced bottom car park, donning wellies in expectation of flooded paths. Soon, we ticked Cetti's Warbler, a very vocal male was on territory at the pond by the sewage treatment plant. A distant cream-topped Marsh Harrier added the second speciality of the site. Some members were lucky enough to hear a booming Bittern near the main hide. We wanted to do the circular walk along the Trent bank, but the flood was impassable even with wellies, so we decided to head towards Tower hide instead.

One of the highlights of the day was a large flock of several hundred Black-tailed Godwits, flushed by a Buzzard.

The flock of Black-tailed Godwits later settled on the flooded fields.

Distant Grey Heron and Little Egret. Later a Great White Heron was also spotted distantly from Tower hide.

Those of us who stayed for coffee and cake at The Paddocks Tea Room were rewarded with wonderful views of a Barn Owl hunting along the floodbank.

A walk up the River Hull in February

A sunny but breezy day, I walk to Oak Road and then up the river Hull until Wawne. There is an uplifting chorus of singing birds, including SOng Thrush, Robin and Wren

 

Song Thrush.

At the lake, I'm pleasantly surprised to find that the lone cob has got a new partner. The pen looks in much better condition than last year's one, which ended up dying after the cygnets hatched. The cob has raised three cygnets to fledgling. Last time I was here, a couple of weeks back, he was encouraging them to practice flying along the lake. A local told me he chased the young off last week.

The resident pair of Mute Swans at Oak Road Lake.

Three Cormorants resting on one of the fishing platforms. It is not possible to walk around the lake if you are not wearing wellies, so this area has far less disturbance than usual.

On the north side of the lake there is a small group of Siskins, feeding low down on the birches.

Three Buzzards are displaying high over Ennerdale. with some mewing.

Usual horse grazing on the river bank.

I check the reservoir. There are Shovelers in the distance. Little Grebes duet their little chortle. The usual assortment of waterfowl are present. It is after I carry on by the river when I come across this cormorant, which emerged from the water having captured an eel. The eel was putting some fight and the cormorant struggled to position it right for swallowing. In the third photo, the cormorant has thrown the eel into the air to catch it by its head, the threads of mucus between the eel and the cormorant are visible. Usually cormorants dive as soon as they see people on the bank, but in this instance it was too busy with the eel to pay me any attention. Once swallowed, it dived immediately. Nice to see there is still an eel population in the River Hull (despite the cormorants!).

Soon after I cross Reigh Carter Way, I can hear the Skylarks singing from the fields. There is a lot of activity, with chasing between individuals.

I'm very pleased to see two Lapwing on the flooded fields, within the Hull city limit.
