Why the Best Farmland Birdwatching Starts Before Dawn

Farmland birds are early risers, and so must you be. A lapwing's call carries across a misty field at first light, skylarks begin their ascent in the half-dark, and yellowhammers start their thin, wheezy song from the hedgerow before the sun clears the ridge. On a late April walk, being in position twenty minutes before sunrise can be the difference between seeing a dozen species and seeing three. The birds are feeding hard after a cold night, and a well-set pair of binoculars turns that activity into something you can watch properly, from a respectful distance.

Setting Up Your Binoculars in the Dark

Do the fiddly work before you leave the house, or at least before there is light to see by. Dioptre adjustment is the step most people skip, and it costs them sharp views all morning.

• Close your right eye and look through the left barrel at something distant and textured. Turn the central focus wheel until it is crisp.
• Now close your left eye and look through the right barrel. Turn the dioptre ring, usually found under the right eyecup, until that side is equally sharp. Leave the central wheel alone while you do this.
• Open both eyes. The view should now be sharp for both, and you can use the central wheel alone from here on.
• Set the interpupillary distance so you see a single circle rather than two overlapping ones. Do this by feel in the dark; you will know when it clicks.

If you wear glasses and your binoculars have twist-down eyecups, twist them down now; if not, twist them up. Getting this wrong is the commonest reason for a dim, tunnelled view.

Reading the Field Margin

Field margins are both the larder and the motorway of farmland: a strip of rough grass, weeds and hedging between the crop and the fence line, where insects, seeds and cover all meet. Point your glass there first.

Walk the headland slowly, stopping every few paces. Scan along the margin rather than across it, letting your eyes follow the line of the hedge. Look for movement at the base of the tussocks, then lift your binoculars and refocus. Birds in margins are often half-hidden, and a dark shape that resolves into a yellowhammer's streaky head is worth the patience. Wet corners and winter stubbles hold the best concentrations early in the year; once crops are tall, the margins become the main show.

Three Birds to Know Well

Lapwing, skylark and yellowhammer are the classic trio of British farmland, and each needs a slightly different approach.

• Lapwing. Look for broad, rounded wings and a slow, floppy flight. On the ground, the green-backed sheen and wispy crest show well in good light. They favour damp pasture and stubble, and the plaintive pee-wit call gives them away. In spring, watch for the tumbling display flight.
• Skylark. The song is the giveaway: a continuous, ascending torrent from a bird that has climbed until it is a speck. Follow the sound, get the bird in your glass, and resist the urge to move closer. On the ground the streaked brown plumage is subtle, and the bird will crouch and run rather than flush.
• Yellowhammer. A hedgerow bird, often on the topmost twig of a hawthorn or a fence wire. The male's yellow head and breast are unmistakable, and the song — often rendered as "a little bit of bread and no cheese" — is delivered from the same perch day after day.

Give each bird time. A lapwing will feed for minutes at a stretch if you stay still, and a skylark will drop back to the ground and carry on as if you were never there.

Fieldcraft That Keeps Birds Feeding

The aim is to watch feeding birds, not to move them on. A few habits make a large difference.

• Stay on footpaths and field edges. Do not cut across a crop or walk into the middle of a field to get closer.
• Use hedges, gateposts and trees as cover, approaching along the line of a hedge rather than across open ground.
• Move slowly and stop often. Birds react to sudden movement far more than to a still human shape.
• Keep your distance. If a bird stops feeding, looks at you and calls, you are too close. Back off and let it settle.
• Keep dogs on a lead and close to you, and leave gates as you find them.
• In spring, avoid repeated visits to the same nesting area. Disturbance at the nest is the real cost of getting too near.

Binoculars help here as much as they help your eyes. From forty metres, a yellowhammer is perfectly visible and quite undisturbed.

Getting the Most From Every Walk

Keep a note of what you see and where. Over a season you will build a picture of which margins matter and which fields are worth a second look. Clean your lenses with a soft cloth before you set out, check the dioptre setting has not been knocked, and keep the strap around your neck rather than in a pocket.

The rewards of an early start are cumulative. A field margin you walk past every week becomes, over a year, a place you know: the tussock where the yellowhammers perch, the wet corner the lapwings favour, the patch of sky where the first skylark climbs. Set your binoculars up properly, stay quiet and keep your distance, and the birds will tell you the rest.
