Understanding heathland bird calls in spring

Spring on the heath: a changing soundscape

As the first warm days arrive, British heathlands wake up. The air fills with calls that are easy to miss if you don’t know what you’re hearing. Skylarks, curlews and stonechats are among the first to announce the season. Learning their voices helps you enjoy a walk more deeply — and it helps you avoid disturbing the birds that are busy nesting.

Skylark: the song that falls from the sky

The skylark is the soundtrack of open country. From February to July, males rise almost vertically, then hover and sing a continuous, tumbling torrent of notes. The song can last several minutes. It is often described as a stream of trills, slurred whistles and little imitations. You may hear it before you see the bird, so stop and look up. The skylark itself is a small, streaky brown bird with a modest crest. It is easy to overlook on the ground, where it blends with dry grass.

Skylarks nest on the ground, often in short grass or a shallow scrape. If you hear a song above you, you are probably standing near a territory. That is a good moment to stay on the path. Walking through tussocky grass can crush eggs or cause a parent to leave the nest. If a skylark flushes from underfoot and gives a sharp “tick” or “prrit” call, you have come too close. Move away quietly and give it space.

Curlew: the bubbling cry of the uplands

The curlew’s call is one of the most evocative sounds in the British countryside. Its name comes from the haunting “cur-lee” whistle, which rises and falls. In spring, listen for the display song: a bubbling, rippling series of notes delivered as the male flies in a wide arc over moorland and heath. The curlew is a large wader with a long, down-curved bill and long legs. It is red-listed in the UK, and its numbers have fallen sharply.

Curlews nest on the ground in open heath, rough pasture and moorland. They are sensitive to disturbance. If you hear a repeated, urgent “wicka-wicka” or a sharp “whaup”, you are likely near a nest or chicks. Keep dogs on a short lead. Do not follow the bird to try to see the nest. A few minutes of your time can mean the difference between a successful brood and a failed one.

Stonechat: the ticking sentinel

Stonechats are the sentinels of the heath. Their call is a distinctive “chack-chack”, like two pebbles tapped together, often followed by a thin whistle. You will usually see the bird before you hear it: a small, round-bodied chat perched on the top of gorse, bracken or a fence post. The male has a black head, a white collar and an orange-red breast. The female is browner but shares the same upright posture and flicking wings.

When a stonechat gives its alarm call — a scolding, rasping “tschek” — it is telling you that you are too close. Nests are hidden in low scrub or among heather. The best response is to back away the way you came. Stonechats often nest in loose colonies, so if one is alarmed, others nearby may be too.

Other heathland voices worth knowing

Spring on the heath is a chorus, not a solo. A few more calls will help you read the landscape:

• Nightjar: a mechanical, churring song at dusk from May onwards. It sounds like a distant engine idling. Listen for a sudden “koo-ick” in flight.
• Woodlark: a soft, fluting “lu-lu-lu” that rises and falls. It often sings in a slow, circling song flight.
• Dartford warbler: a scratchy, hurried warble, often given from the top of gorse. It is a heathland speciality in southern England.
• Meadow pipit: a parachuting song flight with a repeated “pipit-pipit” as it descends.

Each of these birds nests on or near the ground. Knowing their calls helps you keep a respectful distance.

How to listen without disturbing nesting birds

You can enjoy heathland birds and still put their welfare first. A few practical habits make a real difference:

• Stay on marked paths. Ground-nesting birds rely on camouflage, not flight. A footstep in the wrong place can be fatal for eggs or chicks.
• Keep dogs close. Use a short lead in spring and summer, especially on open heath and moorland. Even a friendly dog can flush a curlew or skylark.
• Listen from a distance. If you can hear alarm calls, you are too close. Retreat quietly and watch from further back.
• Avoid drones and playback. Recorded calls can draw birds away from nests. Drones cause stress and can be illegal near sensitive wildlife.
• Take only pictures. Do not move vegetation or linger near a nest. If you find a nest by accident, leave immediately and tell no one the exact spot.

Spring is a fragile, busy time on the heath. By learning the calls of skylarks, curlews and stonechats, you become a better listener — and a quieter guest. The reward is a landscape that keeps singing.
