The Lapwing Vanellus vanellus has traditionally been regarded as a monogamous, single brooded species, defending a single territory. Recent studies involving individually recognizable Lapwings have begun to challenge the ubiquity of these statements,

Capsule Game cover crops in a pastoral region of southwest Scotland supported passerines at more than twice the density found in similar crops in an arable region. Aims To investigate the use of seed-rich habitats (game cover crops) by farmland passe

Grassland conservation headlands were established on intensively managed grassland fields on four farms in Scotland. Vegetation composition and structure, invertebrate activity density (as measured by pitfall trapping), ground beetle assemblage struc

We investigated the potential for released captive-reared grey partridges Perdix perdix to restock regions from which the species has disappeared. Birds were released at two sites in Scotland (not concurrently) from 1997 to 2003 and monitored via spr

We counted songbirds in crops planted on shooting estates specifically for game management purposes on farmland in Britain and elsewhere in Europe. Winter game crops provide cover and feed areas for pheasants Phasianus colchicus and red-legged partri

Some introduced species succeed spectacularly, becoming far more abundant in their introduced than in their native range. ‘Increased niche opportunities’ and ‘release from enemy regulation’ are two hypotheses that have been advanced to explai

The niche hypothesis predicts that some introduced species establish and spread successfully because their new environment provides expanded niche opportunities compared with their native environments. By investigating nestling survival, growth and b

Counts of songbirds during the breeding season on 21 farms across eastern Scotland, UK, showed that up to 80 times as many birds were recorded from game crops as nearby conventional crops. At the same time, butterflies and bumble-bees were, respectiv

Winter mortality, resulting from reduced food supply during a period of agricultural intensification, is thought to have driven population declines for some farmland bird species. Planting of game crops has increased over this period in order to prov
