“The winters must be very difficult in Shetland,” people often say to me. I think they imagine a Shetland winter as an ingrowing or hibernatory season. But my stomping grounds – mapped by quests and curiosities – are more likely to be domestic in the summertime: nest scrapes lined with milky chips of quartz, the intricate flora of bog and moor, pea plants in the garden.
A summer beach is bonny, but douce in comparison to the ravishing and slightly manic Shetland spring, the extreme highs and lows of the tides. As many birds are leaving as arriving. No more Northern Lights, or night skies in which Sirius is a disco ball of hot colour. Come summer, I’ll be foraging for puffballs, chanterelles and ceps, but winter is the time for rich pickings on the shore; the spring tides of March and April being the last chance to harvest bivalves until autumn.
In his poem “Collecting Pipi”, Glenn Colquhoun taps the apparently atavistic brain state of the forager: “They leave suckingly/and clatter/at the bottom/of the bucket./Quietly/the sea feels/with a tongue/round the holes/in her still-hidden/gums.”
Foraging – and I’m sure there are parallels with skip diving and hitting the sales – seems to engineer changes in brain activity and our perception of our place in the world. As a non-scientist, I would still dearly love to understand what’s happening; so, in the spirit of opportunism, please consider this a call for recommended reading about the neuroscience of human foraging. In the meantime, I’ll see what I can do with prose.
Consider a walk to the cockle beds in the lowest tides of March or April. The mud is littered with plundered white shells. Storm-waves have fossicked the bivalves from their shallow roosts and black-backed gulls and other opportunists have raided the survivors on the shore. One live cockle is half-buried in the mud under a mop of seaweed. Hardly a feed, so you return it regretfully to the shallows. It’s fine to be away from the desk: it’s more of a thought than a feeling. You scan the shore and horizon for otters, seals, birds.
Come along a second walk, now. Same low tide, a grund ebb, a greemster o’ an ebb. But we’re going further. That half-hidden cockle is the first of many and a perfect heart-shape, a stained valentine, like a crash-landed space shuttle. The cram of a live cockle in your hand is greed itself, leaking a little as it sooks its lingerie of translucent tissues back into its shell, folding them over frilled siphons and a glimpsed golden yolk. The bladderwrack is saying something in its click-and-trickle language.
As you stalk the mudflats, filling your bag, modest fountains spurt in your peripheral vision. What is that? A doubled pipe is poking out of the mud, scrunching up into a brown, muppet-like face. Clams are the hearts of the muddy shore; sucking in and discharging brine through aortic-looking tubes. Tapped with your finger, the thick siphon winces into the mud.
The ten-metre-wide bay is like a mouth that you probe as if with your tongue, lifting swaths of seaweed, shifting rocks. The more food you find – salty, muddy, muscly, plosive, protein-rich, heavy, free – the more you shrink. As you work the shallows, a pterodactyl-like heron lifts with world-weary wingbeats. Unnoticed, a furry wreath uncoils from its nest of bladderwrack and pours into the water, pelt melting to mercury. Your heart beats faster; you’re beginning to see.
The rocks are shellacked in sea lettuce, a single cell thick. In deeper water are sweet, salty, crunchy kelps, patterned with lacy bryozoans. The yellow feet of whelks smooch over blades of kelp like animate marshmallows. You find mussels in a groin of rock and tear at them. Hidden spines jab you back.
You will quit only when the tide chases you out. Otherwise, you would gather more than you can eat. At the cockle beds you are a hungry ghost, like those souls in Buddhist mythology who are perpetually unsatisfied, because their eyes are literally bigger than their stomachs. As a forager, to be hungry is to become small, but not necessarily to be diminished.
