Rodley Nature Reserve

Rodley

You drive down through what feels like a factory yard, cross a small swing-bridge over the canal then cross the River Aire via a century-old 38m long Pratt truss steel bridge to reach a low-lying area of lagoons and meadows, enclosed on three sides by a meander of the river, so that being on the reserve feels like being on an island. We’re actually on the inner side of the busy Leeds Ring Road, but I feel as if I’ve got a long way away from all that rush.

As a change from my usual approach, I thought I’d launch straight into watercolour for this sketch – no pen, no pencil – which is based on a panorama that I took from one of the hides on a Wakefield Naturalists’ Society field meeting at the reserve in August this year. No field meetings at all this year, which is probably a first for the Nats since the end of World War II.

Greater Black-backed Gull

reeds

10.30 a.m.: On North Ings, RSPB St Aidan’s, a greater black-backed gull is feeding on the carcass of a brown hare. Two crows and several magpies, dwarfed by the gull, have gathered around it, like vultures at a kill on the savannah, waiting their turn in the pecking order. As the gull tears at the carcass with its large bill, we glimpse the long back legs of the hare and the black and white markings on the tips of the hare’s long ears.

At the field centre, there’s speculation about who was responsible for the kill. One possibility is a peregrine. For a peregrine, St Aidan’s isn’t far from the nest site on the tower of Wakefield Cathedral.

Peregrine Pellets?

A few days ago, we were looking at the remains of what looked like a duck or goose, perhaps even a cygnet. Pellets left by the scattered feathers and bones could have been those of a peregrine.

A short distance, perhaps twenty yards, along the track we saw a sternum, the breastbone of a bird, which we thought looked large enough to be a goose or swan. We can’t be sure that it was part of the same kill.

Pellet about an inch and a quarter long.

There were fox droppings nearby, so the red fox was our number one suspect, but, as far as I know, foxes, unlike birds of prey, crows and herons, don’t produce pellets of indigestible material. In my photograph you can see that the two small feathers appear to have been flattened and nipped off at the quill, rather than plucked, which to me suggests fox.

It’s unlikely that the brown hare that we saw the gull feasting on had been killed by a fox, as it was on a part of the reserve that is surrounded by what is intended to be a fox- and badger-proof fence.

When we walked back past the kill nearly an hour later, the gull had moved and three magpies were picking over the remnants.

Bearded Tits

Bearded tits

A small group of birdwatchers have spotted a party of bearded tits by the path to the Reedbed Hide at RSPB Old Moor Reserve. At first I don’t spot them because I’m looking up amongst the seed-heads of the reeds, but they’re down on the ice at the the foot of the stems.

Soon they’re up feeding on the seeds and their colours harmonise perfectly. There are three males with moustachial stripes and three plainer-looking females, or possibly juveniles. I don’t hear any calls, but there’s a busy road not far away, so perhaps I missed the chirrs and pings that are usually the first sign that they’re around.

The lagoon that the Reedbed Hide overlooks is mainly ice-covered. Coot, dabchick, gadwall, mallard and a couple of female tufted ducks are making the most of the open water alongside the far edge. Shovellers are resting close to the reeds.

Ings hide

There’s an even greater expanse of ice over Wath Ings, alongside the River Dearne, with wildfowl confined to a small pool. On the river embankment, wigeon graze alongside Canada geese. A green woodpecker calls from the woods on the far side of the river.

Lesser Redpoll

The bearded tits were a new bird for me, I’ve looked for them before, but I don’t remember ever seeing them; I certainly haven’t seen them showing as well as they did today in the low winter sunlight. Lesser redpoll is also a new species for me – or at least it is under that name. It doesn’t appear in my older field guides because, when they were published, it was considered a subspecies of the North European common redpoll. It’s now a species in its own right and I like its Latin name, Carduelis cabaret: ‘cabaret’ is the French name for a kind of finch. The word cabaret also refers to a small chamber, so perhaps this was meant to refer to the kind of finch that was often kept as a caged bird at the time the German naturalist Müller gave it its name, in his translation, published in 1776, of  Linnaeus’s Systema Naturae.

Redpolls are happier in the tree-tops, nibbling at birch cones, as the three that we saw were doing today, next to the Visitor Centre at Old Moor, as we made our way out.

Stanley Ferry Flash

The same view of Stanley Ferry Flash, near Wakefield, taken by Richard Brook on Sunday, 9 September, 1973 (above), and on Friday, 24 January, 1986 (below). The colliery spoil heap in the background, from one of the Stanley Collieries, perhaps Stanley Deep Drop, has grown, or at least been reshaped in the intervening years.

Part of the spoil heap area became Stanley Marsh Nature Reserve.

Common Reed, Phragmites, has colonised the area, although some reedmace remains. The rough grasses, greater willowherb and water plantain seem to have been drowned out, so I wonder if the whole site subsided, or whether water levels stayed about the same but the reed out-competed the other plants.

Swan Feeding at Fairburn Ings, 1966

One of the pleasures of archiving Richard Brook’s slides of West Yorkshire wildlife habitats of half a century ago is being reminded of familiar places from my earliest birdwatching expeditions. Already in 1966, Fairburn Ings was establishing a reputation for itself as a nature reserve. At that time, if I remember rightly, it was managed by the West Riding County Council.

As he was trekking around the wilder fringes of the area, there are rarely  figures in Richard’s slides, but he wasn’t quite able to crop this little boy feeding the swans out of the frame.

Richard took the photograph on Tuesday, 2 August 1966.

Ferrybridge Cooling Towers

I can make out just three cooling towers at Ferrybridge Power Station.  There had been eight but there had been a catastrophic collapse of three of them on 1 November in the previous year, due to vibration caused by a westerly gale with winds of 85 mph.

Leventhorpe Lagoon 1973

I’ve been making a start on archiving a collection of colour slides taken by Richard Brook (1943-2017), for many years the Conservation Officer of the Wakefield Naturalists’ Society. He photographed the East Ash Lagoon at Leventhorpe from the lagoon’s northwest corner on Sunday, 2 September, 1973. Pulverised fly ash was pumped from power stations into lagoons and left to settle out.

Richard could see the potential of these lagoons as nature reserves and he documented every one of them – along with subsidence flashes and sand quarries -within five or six miles radius of Wakefield, so his collection of slides form a unique record of post-industrial West Yorkshire.

Dust & Scratch Removal

Before.

I’m gradually learning my way around the slide scanning option of my SilverFast scanning program and also learning easier ways to remove specks of dust and other blemishes from the slides.

In Photoshop CS5, I’ve just discovered the Dust & Scratches filter, which is hidden away in the Photoshop Filter Menu under the heading Noise.

After

It’s a lot quicker than using the Spot Healing Brush to individually remove blemishes, although that has it’s part to play too: Dust & Scratch Filter for the whole sky, Spot Healing Brush for getting into more detailed parts of the image.

Drift Ice

There’s a thin layer of slushy ice on a sheltered section of the canal, in the shade and shelter of the sandstone escarpment of Hartley Bank Woods, but some shards of thicker ice have been blown alongside the concrete canal bank and gathered in shards as they’ve piled up against a clump of grass at the water’s edge.

This is probably reed canary-grass, Phalaris arundinacea, which sometimes gets the nickname ‘canal grass’. I’ve even heard it described as ‘designer phragmites’, an alternative to the common reed, Phragmites australis, where space is at a premium!

Rain soon followed this morning’s snow: there’s faint rainbow near the centre of this photograph.

A cormorant flies up from the marshy field known as the Strands. What open water there is here appears to be entirely ice-covered. The small lagoon by Beeston Bridge at the foot of the Balk is also frozen solid so the resident moorhens have lined up on the river’s embankment to peck amongst the rough grasses there. It’s probably marginally warmer over by the river.

 

 

Call of the Wild

11.45 a.m.: As I clear the snow from our driveway I hear an approaching cachophony: an unfamiliar sound . . .  A little dog? A radio? The hooter of a child’s pedal car?

Soon a skein of eighty grey geese appears, three or four hundred feet above the rooftops. It’s a different sound to the argumentative sounding Canadas that we’re more familiar with; slightly deeper and, I think, a wilder kind of call.

They’re heading in the same direction as the skein we saw at breakfast time the other day: south east; so perhaps towards the Humber or the Old Moor RSPB reserve?

Banded Demoiselle

A pair mute swans on the canal have reared four cygnets; we’re told that they started with five, but rearing four out of five is pretty good going.

As they sit together on the bank preening, they’re all making elegant swan-neck movements, like the warm-up for a ballet rehearsal; the two principle dancers flanking the corps de ballet.

A male banded demoiselle flies alongside the canal. In contrast to other damselflies, this one is so dark that it reminds us of the chimney sweep moths that we saw flying amongst grasses in the Dales a couple of weeks ago. It’s the first that I can remember seeing in the valley.

It’s a while since we saw a gatekeeper; a male comes to rest on a bramble leaf amongst the grasses by the towpath. The diagonal streaks on the forewings of the male are scent glands. Males have a habit of patrolling a small territory , typically on the edge of a woodland ride.

Ringlets are the butterflies that we’re seeing most frequently at the moment, mainly alongside hedgerows, especially where bramble is in blossom but even more popular with them is a patch of creeping thistle which is currently dotted with purple flower-heads.

Herons, Storks and Spoonbills

A little egret wades through the weedy waters of a pool between the river and canal, occasionally stabbing at some prey in the water a foot or two ahead of it. A pigtail of a plume hangs down behind its head. ‘Little’ is an appropriate description: it looks petite compared with plump moorhen standing nearby at the water’s edge.

A juvenile grey heron touches down by the pool and steadily ambles along the bank towards the egret, which continues its progress towards the heron. I’m expecting the larger heron to see off the egret, but there’s no interaction between them.

Next to the pool is a nesting platform fixed on top of a tall pole. It was erected when a pair of wild white storks attempted to nest here in April 2004: the first nesting attempt in Britain for six hundred years. Storks like to nest near human habitation but it probably didn’t help that hundreds of birdwatchers flocked to the spot and stood on the towpath under the pole. The pair deserted.

But the good news is that it’s just been announced by the RSPB that spoonbills have nested at their Fairburn Ings nature reserve. They haven’t nested in Yorkshire since the 1700s. Unlike the storks, they were able to nest in peace as they wisely chose the cover of a stand of trees in one of the quieter corners of the reserve and the RSPB didn’t go public with the news until the three young had successfully fledged.

Buzzard and Sparrowhawk

As we walk down the Balk into the Calder Valley, a buzzard flies across in front of us, far enough down the slope that we’re getting an eye-level view of it. It’s surprising how different those long, broad wings look when seen from this unfamiliar angle.

Later a female sparrowhawk circles over the marshy field known as the Strands. At first, against the sky with nothing to judge its scale by, I’m wondering if it could be some larger bird of prey, but it soon flies right over our heads, so that we’re able to see the barring on its plumage and get a better idea of its size.

Little Egret

egret4.30 p.m.: A little egret flies up from the marsh on the Strands, a field between the river and the canal. It’s a bulkier bird than the black-headed gulls which are also flying over the marsh but its wingspan is about the same; the striking difference is that the egret is completely white: no black wing-tips, no grey back. It’s the first time that I’ve seen a little egret on my home patch in the valley.

Askham Bog

Slender tufted sedge, Carex acuta
Slender tufted sedge, Carex acuta

longhorn moth green veined white11 a.m.: Orange tips and green veined white butterflies are attracted to the flowers of jack-by-the-hedge which grows in swathes along the edge of the swampy woodland at Askham Bog Yorkshire Wildlife Trust reserve, southwest of York.

Its white flowers have also attracted a longhorn moth Adela reaumurella, a metallic green micro moth, less than a centimetre in length. My photograph shows a female; the male’s antennae are twice as long, three times the length of its forewing.

Sedges

Slender tufted sedge, Carex acuta (above), has sharp corners on its triangular stems. In my photograph, the male flower spikes are the dangling ochre tassels while the female spikes, below them in the flower head, have two styles growing from each ovary, like the forked tongue of a serpent.

Askham Bog has the largest colony of gingerbread sedge, Carex elongata, in England. In autumn the floppy tussocks of this sedge and its spikes of seeds turn reddish brown. Is that how it gets its name? Is it the colour of gingerbread? Or did it once have some use as a food or herbal remedy?

The colony is in Far Wood, east of the reserve’s boardwalk so wellies are recommended if you go in search of the sedge.

Water Plants

amphibious bistort

The pink flowers of amphibious bistort, Persicaria amphibium (above), are still in bud. It’s floating leaves are pointed at the tip and blunt at the base.

Despite its name water violet, Hottonia palustris, is a relative of the primrose. In my photograph you can see the stigma of the flower in the yellow centre of the foreground flower. In primroses this is what botanists refer to as ‘pin eyed’. Water violet has finely divided fern-like leaves beneath the surface of the water.

Violets

Dog violets grow alongside the duckboards and a few marsh violets, Viola palustris, which have paler flowers with dark veins. Marsh violet has long creeping rhizomes so when we spotted one, we soon found a few more scattered around nearby amongst the marsh plants.

Royal Fern
