Our objectives were to measure

Although urban and industrial-scale agricultural development has caused the BIBO 3304 or global population decline of many animals, a suite of adaptable, generalist species have taken advantage of these novel habitats to become relatively abundant (Bird et al., 1996, Gompper, 2002 and Bonier et al., 2007). At the apex of those food chains are predators which have successfully adapted to human-altered landscapes, often by being nearly invisible to humans (Bird et al., 1996 and Gompper, 2002). For instance, the densest populations of some bird-eating birds of prey occur in urban environments, where they consume large numbers of abundant, often introduced, bird species (Bird et al., 1996, Boal and Mannan, 1998 and Rutz, 2008).
