Surveying the incredible Nightjar on one of our heathland reserves

At 8.30 pm on a sultry Thursday evening in the dying days of June around 30 SWT staff and volunteers gathered on Barossa Common in Camberley to take part in a vital ritual – the annual Nightjar survey.  Over recent decades these incredible, perfectly-camouflaged birds have faced steep population declines due to habitat loss and the drop in insect numbers, but there are promising signs that across sites managed by SWT and other responsible landowners, populations are rebuilding. It’s vital that we monitor the fortunes of this sensitive species closely.

Breaking into small parties, the citizen scientists wander the pathways around carefully-prescribed areas of the site, noting the precise locations and timings of any Nightjar calls or sightings (male Nightjars make a mechanical ‘churr’ and undertake short display flights to proclaim their territories and attract females). At the end of the evening, Conservation Manager Adam Bolton has enough data to form a decent estimate of the size of the population, using the precision nature of the records taken to minimise the risk of double counting.  By 11pm, the final tally suggests that we have identified some 40 breeding territories; a healthy population of Nightjars still calls Barossa home.

Even seasoned conservationists can’t fail to be moved by the beauty of prime heathland habitat as the sun sets over the heather, bracken and woodland edges. For those who have not before seen the boomerang-like display flights or heard the extra-terrestrial-sounding territorial churring of these nocturnal African migrants, the experience won’t be quickly forgotten.

Joining events like these is an amazing way to connect with nature and assist in this essential monitoring work. And it’s your support that makes these surveys – and the ongoing maintenance of the lowland heathland habitats that these captivating creatures depend on - possible. Let’s make sure the magic of Nightjars is here to stay.
