Nightjars, the elusive nocturnal birds once nicknamed “goatsuckers” in English folklore, have been recorded in their highest-ever territory count in the Special Protection Area that includes parts of the South Downs National Park. An ecological survey found 109 nightjar territories in the area, up from 78 the previous year. The increase follows years of heathland restoration work aimed at improving breeding habitat for nightjars and other species.
Record Territory Count Signals a Turning Point
The 109 territories represent the highest number ever recorded in the Special Protection Area that includes parts of the national park. That figure marks a roughly 40 percent increase over the 78 territories logged the year before, a pace of recovery that has surprised even the teams managing the habitat.
Conservationists have described the birds’ return as a remarkable comeback. Nightjars are secretive, ground-nesting birds that rely on open heathland for breeding between May and August. Their cryptic plumage makes them almost invisible during the day, and they are most often detected by the distinctive churring call males produce at dusk. That call is now being heard across stretches of the South Downs where it had been absent for years, consistent with reports of nightjars returning to restored heathland habitat.
How Heathland Restoration Created the Right Conditions
The population surge did not happen by accident. It traces directly to the Heathlands Reunited project, a multi-partner effort coordinated by the South Downs National Park Authority to restore and reconnect fragmented patches of heathland across the park. Heathland, once widespread in southern England, shrank dramatically over the twentieth century as agriculture, forestry planting and development consumed it. The fragments that survived were often too small and too isolated to support breeding populations of specialist birds like the nightjar.
Heathlands Reunited tackled that problem by clearing encroaching scrub, reintroducing livestock grazing and using controlled burns to reset vegetation cycles. These techniques mimic the natural disturbances that historically kept heathland open and rich in the insects nightjars depend on for food. The project also worked to link isolated heathland patches into larger, continuous blocks, giving birds more room to establish territories without competing for the same narrow strip of suitable ground.
The South Downs National Park Authority has documented these habitat management approaches in guidance on supporting heathland birds, noting that nightjar breeding and nesting timing in the South Downs aligns closely with the period when restored heathland is at its most productive for invertebrates. By timing interventions such as cutting and burning to avoid the May-to-August nesting window, conservation teams reduced disturbance to breeding pairs while still maintaining the open conditions the birds need.
Alongside direct habitat work, the project has relied on careful monitoring. Surveyors listen for churring males at dusk and dawn, mapping territories over repeated visits. These methods underpin the latest count and allow staff to see which management techniques are associated with the strongest responses. Over time, that feedback loop has helped refine how and where limited resources are deployed on the ground.
Why Nightjars Matter Beyond the Numbers
Nightjars are not just charismatic oddities with a gothic nickname. They function as an indicator species for heathland health. Where nightjars thrive, the broader ecosystem of heathland invertebrates, reptiles and ground-nesting birds tends to be in better shape. The South Downs National Park Authority has recognised the nightjar as a characteristic heathland bird in the South Downs, meaning its presence or absence signals the condition of the habitat itself.
That is why the increase in churring nightjars matters beyond the headline number. Official updates from the park authority have reported broader gains in heathland bird populations alongside the nightjar recovery, describing the trend as a big win for nature as restored heathlands bounce back. If the same habitat work that benefits nightjars also supports other declining species, the case for scaling up heathland reconnection grows stronger.
The birds also have cultural importance. Their eerie calls and crepuscular habits fed centuries of folklore, including the myth that they drank milk from goats. Today, that mystique helps draw visitors to evening walks and guided events, giving rangers a chance to explain why lowland heath is one of the UK’s rarest habitats and how everyday choices about recreation can affect wildlife.
The Limits of the Good News
Coverage of the nightjar recovery has leaned heavily on the positive framing, and there is reason for optimism. But it is also fair to ask how durable this rebound really is. The 109-territory count comes from a single survey period, and population numbers for ground-nesting birds can swing sharply from year to year based on weather, predation pressure and disturbance from recreation. A cold, wet May can suppress insect availability and reduce breeding success even on perfectly managed heathland.
There is also a question of scale. The Heathlands Reunited project operates within the boundaries of the national park and its immediate surroundings. England’s total heathland footprint remains a fraction of its historical extent, and nightjars outside the South Downs face many of the same pressures that originally drove the species into decline. The record count in one protected area does not, on its own, reverse a national trend.
What the South Downs results do demonstrate is that targeted, sustained habitat work can produce measurable gains within a relatively short timeframe. The jump from 78 to 109 territories suggests that once heathland reaches a certain quality threshold, nightjar populations can respond quickly. That speed of response matters for conservation planners deciding where to invest limited funds, especially when budgets are tight and competing land uses are intense.
What Comes Next for the South Downs
The next phase of work in the South Downs is focused on consolidating recent gains and reducing pressures that could erode them. The park authority’s programme for ongoing heathland care emphasises long-term management rather than one-off restoration, recognising that without continuous grazing, cutting and control of invasive species, heathland will quickly revert to scrub and woodland.
Managing recreation will be central to that effort. Many of the most productive nightjar territories lie close to popular paths and car parks. Dogs running off-lead can disturb ground nests, while increased visitor numbers raise the risk of wildfires. Rangers are working with local communities and user groups to promote simple behaviour changes, such as sticking to main tracks during the breeding season and keeping dogs close on sensitive areas.
Technology is also playing a role. The park’s interactive online maps allow visitors to see where key habitats and access routes overlap, helping them plan walks that enjoy heathland scenery without putting pressure on the most sensitive sites. For land managers, the same mapping tools make it easier to coordinate work across multiple ownerships and to identify gaps in the heathland network where future restoration could have the greatest benefit.
Looking ahead, conservationists in the South Downs see the nightjar story as both a validation and a warning. It validates the idea that landscape-scale projects can reverse declines for specialist species when they are properly funded, carefully monitored and sustained over many years. At the same time, it warns against complacency: the gains remain vulnerable to climate shocks, budget cuts and land-use changes beyond the park boundary.
For now, though, the soundscape of a summer dusk in the South Downs has been transformed. Where silence once marked depleted heath, the mechanical trill of nightjars now carries across the heather. The challenge for the next decade will be to ensure that this resurgence is not a brief spike in the data but the foundation of a stable, thriving population that can weather the pressures still to come.
