“…In the months that follow, i.e. May and June, grass vegetation is higher, so food is not as easily accessible and detectable for Meadow Pipits (Butler & Gillings 2004, Douglas et al 2008, Vandenberghe et al 2009, and foraging mobility is restricted (Devereux et al 2006, Douglas et al 2008. We suspect that lowland meadows, which are mowed once or twice per year, provide low vegetation; in lowland and upland pastures, low vegetation is also achieved by grazing.…”

“…Recent work by Devereux et al (2006) demonstrated that under experimental conditions, the density of Ryegrass Lolium perenne cultivars had no detectable effect on the foraging and vigilance behaviour of Starlings Sturnus vulgaris. In our more complex grassland system, the availability of food to Meadow Pipits may be a function of not only vegetation height and density, but also plant diversity and structural complexity.…”

“…It is generally accepted that one of the major consequences of these changes, is a reduction in food abundance for wild species that feed on ground dwelling arthropods. However, predators may also be affected if the changes limit access to prey, even if prey remain abundant (Devereux et al. 2006).…”

“…It has been stated that some ground foraging bats avoid areas with dense ground vegetation (Arlettaz 1996). However, there are no studies that directly evaluate how ground clutter affects access to prey by bats, and few studies for other groups of predators of ground dwelling arthropods (but see Devereux et al. 2006).…”
