My favourite sentence in JA Baker’s The Peregrine is “The hardest thing of all to see is what is really there”. It comes at the start of chapter two, where Baker turns his attention towards a discussion of what a peregrine is and the data of his observations. The methodology, if you like, behind the book’s slow unhinging from the human world, to that of the falcon’s. It is my favourite sentence not because it encapsulates the bird or the book in its entirety but because it encapsulates the writing. You can read The Peregrine many times and it will change and shift. You will notice new things, new sentences, overlooked details. It is like going birding, repeatedly in the same spot, and seeing different birds every time.
I spent the summer working with The Peregrine exploring the archive of pollution in its writing, within the toxic context of writing about polluted places. As usual at the end of a long project I can’t retreat back into books. Instead on holiday with my partner and her family in Cornwall, at the wet, salt-glazed selvedge of England, we retreated into wildlife and the basic elements. Sea breeze, salt air, granite and heather again. We found three peregrines. A big adult female skimming the fields between Cape Cornwall and St Just. A bulky swarthy juvenile bludgeoned through a rainbow off the Lands End cliffs. The most spectacular was another juvenile, a small tiercel, tussling with a raven: stooping at a bird it couldn’t possibly catch, flashing its talons, carving up the air every side of it. The raven rolled over, raised its claws and barked. The falcon thought again and circled through the air, tucked its wings in and fell to earth like a dead weight.
I never saw if it was a successful stoop. I think it probably wasn’t – it is not the first time I have seen a young peregrine repeatedly circling, hassling and stooping over prey it has no hope of catching, as if it was playing, practicing, sharpening its reactions on the whetstone of actual living prey. At the same time, if I hadn’t seen it, I probably wouldn’t have believed it. Peregrines playing with ravens? Yeah right. Once a birder, always an incorrigible sceptic.
When I first read The Peregrine I regarded it as the ornithological gospel truth. The second time I read The Peregrine I thought it was an extraordinarily written piece of fiction, unavoidably stringy (string: the birding slang for made up, hoax observations). Ever since then, every time I read it, I change my opinion about it. My inkling is that its more contentious observations will eventually be proven true, or at least possible. In the past few years urban peregrines have been recorded hunting woodcock after dark, which Baker mentions. I recently came across a short paper about a peregrine hovering – again behaviour mentioned by Baker that I had in the past regarded as being impossible. These behaviours might be really there, but the hardest thing to see. Baker is, in the terms of Immanuel Kant, an “enlightened” observer – committed to the truth of his own impressions, observations and thought, without relying on received wisdom – or myth.
Yet the question of authenticity and Baker never goes away, though I dearly wish it would. Nothing is gained or taken away by pronouncing on the veracity of a text with a rubber stamp of truthful authenticity or fiction. That is as bad as people who would reduce the text to being about one thing, confidently pronouncing on the meaning of The Peregrine as if it was a fixed, easily pigeonholed story.
Having spent the summer exploring it as a depiction of its time and place, I still think it’s a pre-eminent example of a portrayal of a landscape poisoned by “the filthy, insidious pollen of farm chemicals” (15), a place where for the falcons “foul poison burned within them like a burrowing fuse. Their life was a lonely death, and would not be renewed” (118). Derek Ratcliffe, the naturalist who discovered the eggshell-thinning effect of DDT, wrote in his monograph The Peregrine Falcon, that had the decline of the peregrine in the 1950s and early 60s continued unabated, “extinction of the Peregrine in Britain could have occurred by 1967” — the year when The Peregrine was first published. It is important not to forget this, or forget about the persistence of chemicals in the environment. Due to DDT’s chemical stability it remains present in the environment to the point where in 2002 still “No living organism may be considered DDT-free”.
Baker’s writing persists due to its potency. In its synthesis of science and poetry it is, I think, unparalleled – a pre-eminent example of how to write about nature. Six years ago when I first read of his aim to follow the peregrines of Essex “till my predatory human shape no longer darkens in terror the shaken kaleidoscope of colour that stains the deep fovea of his brilliant eye” (41). I thought, for six years, that deep fovea was just a poetic expression of the materials of vision, one with a nice tang of Romantic mystery about it. It wasn’t until a week ago, reading Tim Birkhead’s excellent Bird Sense that I discovered falcons have two foveae. The fovea is the part of the retina where the visual image is sharpest. Where a bird has two, one works for close up and one does distant vision. In Birkhead’s words, “the deep fovea… acts like a convex lens in a telephoto lens, effectively increasing the length of the eye and magnifying the image to provide very high resolution”.
The hardest thing of all to see… Baker attracts light. Writers Robert Macfarlane, Mark Cocker and the academic David Farrier have all discussed Baker’s prose in terms of light – as luminous, or flaring – as well as his use of light. Where we have light, vision follows. Macfarlane also describes Baker as having “an obsession (ocular, oracular) with the eyeball”, adding that “One of the many exhilarations of reading The Peregrine is that we acquire some version of the vision of a peregrine” (154). The more I learn about peregrines the more I realize the extent to which Baker’s writing embodies them. Further and deeper than just the aerial perspective Macfarlane talks about. Baker’s writing is like the magnified, high-resolution vision of the peregrine’s own deep fovea.
