Nightjar Caprimulgus europaeus and Woodlark Lullula arborea– recovering species in Britain?

Abstract: The Nightjar Caprimulgus europaeus and Woodlark Lullula arborea are identified as species of conservation concern at both a UK and a European level on account of historical declines in their population sizes and ranges. The UK populations of both species have increased significantly in recent decades and this paper reviews the extent, nature and causes of these population changes, based on evidence from national surveys and autecological studies. It also considers the future prospects of both species in the fa… Show more

“…Wright (2006) found similar clutch sizes and breeding success within Breckland for heathland and plantations (clear fell and restocks). If this was representative of the population, the limiting factors may have been more closely related to habitat composition, such as the age structure of forest stocks, where higher territory densities of Woodlarks occur in plantation 'coupes' of 2-4 ha and mainly a tree age of less than 10 years (Langston, Wotton et al 2007). Both are likely to change over time, while milder winters may have helped to create less favourable conditions for Woodlarks, within the field-layer by creating more ground cover and less bare ground.…”

“…This allowed us to compare a heavily used area containing amenities and 28.3 km of walking and cycling tracks (North) with a relatively undeveloped area containing no amenities and only 3.3 km of walking and cycling tracks (South). Based on FC GIS data, there were comparable amounts of heathland and clear-fell habitat in similarly sized patches between the North and South (see Results), which we considered to meet the criteria for typical breeding habitat for Nightjars (as described for the UK by Ravenscroft 1989, Liley and Clarke 2003, Langston et al 2007b). …”

“…Between 1972 and 1992, its breeding range decreased by more than 50% (Stattersfield andCapper 2000, Gregory et al 2002). The historic causes of decline are considered to be loss of breeding habitat, primarily through a combination of loss of heathland and changes in availability of open-ground habitat within forest plantations, together with potential factors operating on overwintering grounds and migration stopover locations (Langston et al 2007b). Recent evidence suggests that some UK Nightjar populations increased by at least 36% between 1992 and 2004 (Conway et al 2007).…”

“…For example, Woodlark occurrence could have been affected by changes in food supply; in particular caterpillars, beetles and spiders, which form an important component of the diet of Woodlarks during the breeding season (Langston et al 2007). Improved weather conditions during winter might have affected demographic components such as survival.…”

“…Improved weather conditions during winter might have affected demographic components such as survival. Climate changes may have affected Woodlarks, but the nature of these effects is considered equivocal in Britain (Langston et al 2007).…”
