Winter Chills but Nature Thrills…

Winter Chills but Nature Thrills…

I had been wondering if she would be there. I had encountered what looked like the remains of her feasting along the path. The telltale circle of piled feathers that indicated a pigeon devoured, plucked breast up, the carcass taken for final pickings by its captor.

Usually I would attribute such feathery leftovers as the work of a sparrowhawk but today the pile is huge, with a wide radius, as if something far more powerful has torn and plucked the bird. Around me too the landscape has shifted closer to winter when I would most expect to see her again.

And there she is, perched midway up the pylon, busy preening and cleaning herself. Her size and plumage tell me she is an adult female peregrine, returning hopefully to her wintering grounds – my ‘local patch’. Her dark black hood speaks suitably of the skilled executioner she is. Indeed at my very feet another pile of pigeon feathers ruffle in the breeze. She has been busy and now clearly is engaged in a post-postmortem cleanup.

Peregrines must bathe daily to clean off the inevitable blood and guts of their hunting lifestyle. It is a little observed behaviour of the bird, known better for its aerial supremacy and powerful stooping dives on prey. It is behaviour that I have been lucky enough to observe at a local gravel pit. I watched, in that instance, a young peregrine, bedraggle itself at the water’s edge, unusually vulnerable and ruffled. Nothing mobbed it, no crow swooped down to take advantage of the predator’s pause. I wonder if it was just simply because the peregrine was unrecognizable, stripped of its threatening prowess and hidden in its bath-time obscurity.

Such behaviour was written about by that great admirer of the peregrine – JA Baker, who found his local peregrines returning again and again to a quiet spot along his local river in Essex. More recently a peregrine has been filmed washing at the edge of the River Thames in Central London, observed by the many tourists along the embankment.

The peregrine before me today may be a bird that has bred not too far away. Increasingly peregrines are being observed in the breeding season in nearby larger towns such as Watford and Luton, usually perched high on an industrial structure, always with a precipitous view and teetering ledge. Wherever this bird has come from, she commands the airways as she hunts from her pylon peaks – her own corridors of power.

I, for one, welcome the return of the peregrine – I expect the local farmer does too for it is the ultimate bird scarer! The bird never fails to add a thrill to the wider landscape and makes those ugly pylons objects of interest, to be scrutinized carefully lest they conceal a roosting peregrine.

Autumn has its own spring for while leaves fall and plants die back there are new arrivals, like the peregrine, that are as welcome a sight as returning migrants in March. Though they arrive on cold winds to a damp landscape they revitalize it with their busyness and the drama of their flocks. On the dullest day there is never a dull moment and this is nature’s gift to us if we can brace ourselves in the cold months ahead and leave the dull subfusc eye of electric bulbs and ceilinged spaces to get outside in it!

Strange Summer Soundtracks!

 

Twice this year I have found myself listening to birds that do not sound at all like birds! The first occasion was whilst camping in Dorset amidst the wild and beautiful heathland bordering the edge of Poole Harbour…

On a still, warm evening in late spring and early summer you are almost guaranteed to hear the strange song of the Nightjar issuing out from dusk until dawn on the Dorset heathland. I say ‘almost guaranteed’ because on the very, seemingly perfect, night I chose to lead a small group out into the twilit heathland a deafening silence greeted us! We had to wait a long time but did eventually hear a distant male bird’s song, but not before my birding credentials had almost been teased to tatters. Of course, the very next night, the campsite itself played host to several male Nightjars happily calling loudly high above our tents!

The song of the Nightjar is best described as a continuous churring sound, rising and falling in pitch. If you hear it you may be forgiven for attributing it to an amphibian or even to a piece of machinery. The Nightjar’s song contains 1,900 notes per minute and in the warm, stillness of a summer’s evening, seems to fill the air, mixing with the rising heathland scent of heather and pine. It is a magical experience reminiscent of holiday evenings in the South of France listening to cicadas as the light fades and the day cools off. Perhaps this is what J.A. Baker had in mind as he wrote his beautiful descriptive prose of the Nightjar’s song:

Its song is like the sound of a stream of wine spilling from a height into a deep and booming cask. It is an odorous sound, with a bouquet that rises to the quiet sky. In the glare of day it would seem thinner and drier, but dusk mellows it and gives it vintage. If a song could smell, this song would smell of crushed grapes and almonds and dark wood. The sound spills out and none of it is lost.” (J.A.Baker, The Peregrine, 1967)

The bird itself is no less peculiar than its song with a wide, gaping mouth, reinforcing a sense of the amphibian. Indeed, its closely related family of foreign cousins are called ‘Frogmouths’. During the day, it remains perfectly hidden, its brown plumage matching the dry litter of the heathland floor – not revealing itself unless practically stood on.

Like the nighttime jarring of the Nightjar another, much smaller bird, has recently been singing its equally un-bird-like notes much nearer to home – at Heartwood Forest on the edge of St Albans. At this time of year, Heartwood is alive with the buzz of insects, cashing in on the abundant supply of nectar from the wildflowers blooming in the warm sun. Calling grasshoppers and crickets herald the start of lazy summer days while boisterous buzzing bees share petal space with the altogether quieter and more delicate butterflies.

Out walking the dog at Heartwood I paused to take in the scene and listen to the buzz all around me. As I listened I realized that above the stridulations of the grasshoppers a louder, more persistent ‘grasshopper call’ dominated. Almost identical to the song of its insect counterparts this was no insect but a little brown bird aptly named the Grasshopper Warbler.

Like the Nightjar’s song the Grasshopper Warbler’s reeling notes – likened to the sound of a free-wheeling bicycle or a winding fishing rod spool – rise and fall in pitch and volume as the little bird, its whole body vibrating with the sound, turns its head this way and that. The resulting ‘spray’ of notes has a ventriloquistic quality making it very difficult to locate the bird, often perched just above the long grass on a twig or bush.

Once spotted, the little bird is nothing much to look at with its mottled brown plumage and bright pink legs. Like the Nightjar, the Grasshopper Warbler is perfectly camouflaged and designed to remain hidden and, as a result, both birds are heard far more often that they are seen. This visual secrecy seems to amplify their strange un-bird-like songs and, although unlikely to be heard together, add a layer of mystery to the summer landscape wherever they sing.

The Nightjar is sadly now absent as a breeding bird in Hertfordshire but, as I write this, the Heartwood Grasshopper Warbler is still singing his heart out and proving unusually showy. If you do get a chance to hear him, or indeed a Nightjar elsewhere in the country, I’m sure their strange summer soundtracks will captivate you!
