Nest Robber

A COMMOTION before breakfast; six Blackbirds and a Mistle Thrush are gathered in what looks to me like indignant rage around a Magpie on the back lawn which is down at the edge of the pond, attacking a plump nestling, pecking at its head. I know that I should no more wish that Magpies wouldn’t take the chicks from ‘our’ back garden nests than I should wish that Osprey’s shouldn’t swoop on trout or that lions shouldn’t attack zebras but it’s difficult not to feel involved as this turns out to be chick from a Blackbird’s nest in the Ivy behind our herb bed.

We’ve been following the progress of the parents’ nest-building and feeding from the kitchen window, only yards from the nest. They’ve been busy over the past few days shuttling in a supply of worms and insects.

Deciding that it would be too late to rescue this chick anyway, I leave the garden birds to sort it out between themselves.

But, after breakfast, when I go down the garden to open the greenhouse, I discover a second chick. It looks like a miniature oven-ready chicken, naked, plump and bleary-eyed, with a row of plastic-looking quills along its stubby wings. Only it’s parents could love it. It’s got a spot of blood near the base of its bill but is otherwise unscathed. The Magpie must have been disturbed before this chick suffered the fate of its sibling, which the Magpie carried off down to the vegatable beds to finish eating.

I put my head into the Ivy and with some difficulty spot the nest, on a twining branch on the far side of the hedge. With a stick I poke away the remains of a third chick, hanging over the nest from a twig, which the Magpie had evidently killed in its attempt to make off with it.

I retrieve the surviving chick from the lawn and place it so that it’s as comfortable as it can be in the nest. It’s still warm and, I guess, healthy enough.

I’m anxious that the parents will have desserted the nest but by the end of the afternoon they’re back again, so it looks as if they’ve found the youngster. A day later male and female are still taking turns to pop in with food so it looks as if the Magpie hasn’t been back . . . so far.

Wigeon Sketches

I’VE GOT a mental image of the Wigeon but I realise, when I start drawing the real life bird from the Main Hide here at Anglers Lake, that it doesn’t quite fit. For one thing, when I see this drake from in front I can see that its head is more rounded than I imagined. And I’ve over estimated its size; when this drake swims close to on the shore I’m surprised to see that the he is the same size as a Tufted Duck that is loafing by the water’s edge. The size ranges of the two species overlap but in general the Tufted is the smaller species.

Angler's Lake from the Main Hide

It’s only after I’ve been drawing for a while that I realise that this drake has a companion; the female. As I’ve written in my note she ‘easily blends into the background of grey, rippled water and stony banks’. But she does make her presence known when a rival female swims by. It’s the duck rather than the drake who challenges the rival.

Penelope’s Web

The Latin name for the Wigeon is Anas penelope. In Greek mythology penelops  was a sacred bird, a purple-striped duck. Penelope is better known as the wife of Odysseus who stayed faithful to him during his 20 years away, fighting in the Trojan War and on his protracted voyage home. Her determination in dealing with rapacious suitors in her husband’s absence seems to fit with this female Wigeon’s behaviour. One legend has it that Penelope, daughter of Icarius of Sparta, was exposed at birth – the traditional Spartan way of weeding out any weaker offspring – but she was rescued and nurtured by penelops the duck.

But I wonder if the connection between the Wigeon and Penelope actually refers to the web-like pattern of the female. Penelope promised that she would choose one of the suitors as her husband when she had finished weaving a shroud for her father-in-law. Secretly, she unravelled her weaving every night so ‘Penelope’s web’ has become a phrase for any project that is indefinitely delayed. A possible derivation of the name Penelope comes from the Greek for ‘web-face’ or ‘weft-face’.

North Landing

 

IT’S SO WINDY here at North Landing, Flamborough, East Yorkshire, that even the gulls are having difficulty making any progress inland; a gull version of Marcel Marceau’s ‘walking against the wind’ mime. A flock of pigeons is no more successful; they wheel around over the bay and veer off on a less wind-buffeted course.

Flamborough Head marks the border between sea areas Tyne and Humber, pointing out towards Dogger in the centre of the North Sea and German Bight on the far side.

Strong winds tend to bring seabirds in towards this six mile promotory of chalk cliffs, making it a favourite location for ‘seawatching’ but unfortunately today it’s blowing in the wrong direction. If it’s blowing from any direction between north-west and east it can bring gulls and auks, skuas and shearwaters closer to the shore but today it’s blowing from the south-west, tending to keep them out at sea.

You might expect to a lot of white-topped waves in such a strong wind but it seems to have the opposite effect, flattening the crests before they become top heavy. At the foot of the cliffs there’s an effect like beaten brass where gusts bring turbulence down to create temporary patches of smoother sea.

As a change in my watercolour of the cliffs, I started directly with my brush, with no preliminary drawing, painting the shapes of sky, cliff-top and sea separately, as if they were individual pieces of a jigsaw. A contrast to my habitual pen plus wash, which I used in my quick sketch of Howden Minster on our coffee break on the way here this morning.

The Barn Owls of Low Laithes

This Barn Owl was found lying by the side of the M1 near junction 40 earlier this week. A member of the Wakefield Naturalist’s spotted it and brought it to the meeting on Tuesday. Sadly, this if a first; at the meetings of the Wakefield Naturalists’ Society that I’ve attended over the last 40 years, I don’t ever remember anyone bringing in a dead bird but this was apparently a regular feature of the society’s meeting in the Victorian period in the bad old days when one of the axioms of keeping biological records was ‘what’s hit is history, what’s missed is mystery’. Even some of the founding fathers of conservation like Audubon used the gun to collect huge numbers of birds, and not just strictly for reference purposes when illustrating his Birds of America, he apparently enjoyed the sporting aspect of shooting wild birds.

There’s a record of an Otter which was shot on the Calder at Stanley on 3 February, 1869. Rather worryingly there’s a note in the Wakefield Naturalists’ Society Annual Report for 1883 (illustrated here with an engraving by Thomas Bewick, or one of his followers):

 Otter – Lutra vulgaris. Several have been obtained.

The Wakefield Naturalists’ Society was founded in 1851, ten years before the Yorkshire Naturalists’ Union, which celebrates its 150th anniversary with a conference on The Ever-changing Flora and Fauna of Yorkshire at Garforth on 19 March this year. Obviously there had to be a network of naturalists’ societies before a county-wide Union could be formed.

Coming back to the unfortunate Barn Owl; it’s hunting habits, flying low over open, scrubby grassland, in the half-light of evening are sooner or later going to put it on a collision course with motorway traffic. Low Laithes golf course provided a hunting territory for Barn Owls as their numbers began to recover locally in the 1980s. They’re continuing to spread around Anglers Country Park today.

Appropriately the place name Laithes comes from the Viking word for barn. My Walks around Ossett follow circular routes around the town from Mitchell Laithes in the south-east to Low Laithes in the north-west.

When I was checking out the Low Laithes walk for the booklet, I came across a familiar-looking image of a Barn Owl. Flags and signs at Low Laithes golf course are emblazoned with the owl logo I drew for them back in the late 80s or early 90s. It’s even been carved in bas-relief in sandstone by the entrance gates; the first time I remember anything of mine being carved in stone.

Scrubland

The Runtlings, Ossett; The winter hedgerows are busy with birds: Greenfinch, Great Tit, Long-tailed Tit and – probing the leaf-litter beneath trees – a few Redwings. A Kestrel hovers over the rough, grassy mounds on waste-ground around Dewsbury Sewage Works.

In my childhood, rough grassland dotted with thorns was a familiar habitat around old collieries, factories and railway sidings. Much of this ‘brown land’ has now been reclaimed for housing and office parks, and today, when more thought goes into landscape design, areas that would once have been left as derelict have been transformed into community parks with fishing ponds, copses and little meadow areas but, because of my childhood memories of roaming around post-industrial landscapes, I feel a touch of nostalgia for these pockets of unkempt scrubland, the hunting ground of the Kestrel.

Towpath Birds

Each bird has it’s distinctive way of getting across the canal;

The Moorhen has the most amphibious method, combining land, air and water for the short journey. As it sees us approach, it pauses on the towpath, stalks a few tentative steps to the bank, launches itself into the air with limited effect then staggers along the water surface for a few paces – with the out of control momentum of someone jumping onto the platform before the train has stopped – before settling to swim the last yard or so to the seclusion of the bankside vegetation.

The Wren zooms along, wings a-whir, from the undergrowth on the towpath side to the hedge on the far bank.

A small group of Long-tailed Tits take a roller-coaster flightpath from the tops branches at one side to those on the other. Repeated wing-beats interspersed with short rests result in their bouncing flight.

A pair of Mallards swim across with a surreptitious air. The drake might be trying to avoid the attention of rival males. Later we see a duck closely pursued by two drakes flying up river.

Birds at a Glance

chaffinchThese aren’t drawings of the birds’ ‘true’, accurate appearance – it would be easier to study a bird book for an authoritative version of that – but they aren’t drawings of the birds as I saw them either; they’re drawings of the way I remembered the appearance of the bird after I’d looked at it for as long as possible, which wasn’t long enough, through binoculars.

This way of drawing varies from my normal approach where I look and look and look again, building up a drawing from dozens, probably hundreds, of little observations. blackbirdThat’s not an option with most of the birds in our garden. I took mental notes of shape and colour during my one lingering look at each bird and then tried to stick to that, rather than revert to the familiar picture of, say, a Blackbird, that I might already carry in my mind.

I gave myself license not to worry if the final drawing didn’t look all that much like the bird. As I say, I could have referred to a bird book if that had been my aim but these are the colours and the shapes, as accurately and honestly as I could transfer them from memory to paper.

The species I drew are male Chaffinch, Starling, female and male Blackbird, Great Tit and Woodpigeon. I used an ArtPen with brown Noodler’s waterproof ink and Cotman watercolours.

The Hawk and the Squirrel

Harris HawkWatching a Grey Squirrel carrying bedding to its drey the other day, I was thinking what an easy life these suburban squirrels must have, with no natural enemies apart from the occasional Fox, which can’t follow them up into the tree-tops. But the squirrels of Spring Mill Park must be well aware of one powerful predator that has been hawking around the area for the last 14 years; this North American Harris Hawk, Parabuteo unicinctus, one of three which belong to a local falconer.

grey squirrelHe exercises them regularly but confides to me that it’s now getting a bit too much for him. When the bird goes down on prey it’s not like a retriever dog, it won’t bring the prey back to him, so it might end up half a mile away – as the hawk flies – up the slope in one of the pastures between Spring Mill Park and the motorway.

This hawk can easily tackle prey such as Rabbits and Magpies but if you’re hawking for Grey Squirrels – which, for all their cuteness, are often seen as a pest species, here in Britain where they’ve been introduced – the hawk needs to be equipped with special leg-guards as the squirrel, when caught, can swivel around and use its impressive incisors to bite into the back of the hawk’s legs, potentially inflicting permanent damage.

Flying weight is critical for hawking; fly a bird that’s even a few grams over its ideal weight and it will happily soar about all day without bothering to go for prey. This female Harris Hawk, I’m informed, needs to weigh in at precisely 2 pounds, 1 ounce and 3 grams, when it is taken out to hunt.

goshawkThe falconer was once surprised, when he was calling back one of his hawks, by the sudden appearance of a Goshawk which flew down and perched on the fence nearby. It had jesses so he managed to get near it and take it back to his avairy. The ring, which all captive falcons wear, revealed that it had been lost by a falconer who lives at Addingham, 23 miles to the north-west of Spring Mill, so he was able to reunite the bird with its owner.

Sparrows on the Shed

roofing felt x 60

This photograph looks rather like a scree-slope on a Lakeland fell but in fact each of these slate-like fragments is less than a millimetre across, smaller than the commas on this page. It’s a piece of roofing felt taken at 60x magnification through my microscope. The felt is bitumen-coated with a ‘green mineral’ finish, but it looks browner in my photograph. The flaky shapes and the colour make me guess that this is a green variety of Muscovite mica called fuchsite. The flakes (laminæ) of Muscovite are thin and surprisingly flexible, so they’re ideal as a coating on rolls of roofing felt.

There’s another mineral present; the rounded, glassy mineral near the bottom left-hand corner is a worn grain of sand, silica.

Fuchsite is rich in chromium but like other micas, as a form of silicate, it has a chemical composition based on aluminium, silica and oxygen (AlSi3O10). Micas are part of the group of minerals known as Phyllosilicates or sheet silicates, which take their name from phyllon, the Greek for leaf.

sparrows on the shedIt was sparrows pecking on our newly felted shed roof that prompted me to take a closer look at its composition. Why should sparrows feel the need to peck at flakes of mica?

Muscovite is 2-4 on the Mohs scale of hardness, depending whether you’re testing the softer ‘sides’ or the harder face of the flakes. This means that it’s somewhere between a finger-nail and a pocket-knife in hardness, so the sparrows might swallow it as a form of ‘gritting’. The flakes might be used in the bird’s gizzard to help grind down the seeds and grain that form its staple diet. Fuchsite is made of clayey minerals so it might also have medicinal properties that help with digestion, just as we’d take kaolin, a fine white clay that is another form of sheet sillicate.

sparrows on a wallSparrows will also peck at mortar on walls (right), which gives them access to more minerals; silica in the sand and the calcium carbonate in the cement.

When Paul and I put the new roofing felt I predicted that the sparrows would love it: “It’s like putting a new sheet of Tydsan in a budgie’s cage!”

Tydsan is the trade name of sheets of sandpaper, cut to size.

“Our budgies had to make do with newspaper in their cages!” Paul tells me.

Fieldfares in the Crab Apple

redwingredwingsWhen the snow returned yesterday morning almost an inch fell, although it wasn’t as cold as it was after last year’s snowfalls. When I’ve cleared the driveway it’s been powdery but yesterday afternoon it was just starting to turn slushy, so it was heavier and slushily sticky to clear from the paving slabs. Powdery snow leaves the driveway cleaner; slush leaves it damp and filthy.

golden hornetAs the snow fell, Blackbirds, Fieldfares and Redwings came to the Golden Hornet crab apple, the one that we pruned on Monday. The snow-covered little apples, golden until mid-autumn (left) but now frosted and brown, proved a big attraction. We counted eight Redwings and five Fieldfare around midday, although I guess that at times there were more.

redwingfieldfareMy pen and ink drawings from my 1979 Sketchbook of the Natural History of the Country Round Wakefield don’t do justice to these attractive winter thrushes. The Fieldfare’s light grey, chestnut and whitish plumage is striking against a snowy landscape, as is the chestnut red beneath the wings of the Redwing. I often have difficulty picking out the red of the Redwing when I see it in silhouette in bushes or in flight but it was very obvious today, at close quarters seen through the 10 x 50 binoculars that I keep by the studio window.

The shapes of the birds were different today; Blackbird, Redwing and Fieldfare all had a more rounded silhouette as they had their feathers fluffed out against the cold.
